Pongbot PACE S PRO: One minute review

The Pongbot PACE S PRO has genuinely changed how I approach solo practice. It’s a major step up from my old Slinger Bag.

The PACE S PRO is built for serious training. It goes well beyond basic ball feeding, combining mechanical speed with player tracking and smart drill logic. It’s ideal if you want structured, high-volume hitting with full control over difficulty. The pace, spin, and variation keep sessions productive.

This isn’t for someone looking to casually hit a few balls after work. It’s for players or coaches who want structure, repetition and challenge on demand.

The hardware holds up well. Spin changes are quick, movement is fluid, and ball delivery stays consistent even at higher speeds. Battery life supports long sessions without fuss, and the app makes switching drills or settings straightforward. The included sensors add extra functionality – as the machine knows in real time exactly where you are on the court.

Build quality has been good during the one month of testing, though parts like the hopper and wheels do feel a bit fragile. That said, I’ve had no problems so far.

This isn’t a device you learn once and forget. You’ll keep finding new ways to use it. The presets are solid, but the real value comes when you start building and experimenting with your own drills. If you already train with data or track your sessions in detail, this machine can slot into that routine and raise the intensity.

It’s not a small purchase, but if you’re serious about your tennis training, it justifies the cost. Especially if you can pick it up on a discount. For those that want something dead simple, there are cheaper options out there. But if you’re willing to dig in, the value really shows.

All of these features, especially with the AI modes and sensor integration, are unmatched in this price range. It won’t replace a coach, but it can sharpen your sessions in ways most machines can’t. I wouldn’t go back to a basic ball launcher after this.

Pongbot PACE S PRO review: Design and how it holds up

• Sturdy and quiet during use, with good on-court stability
• Easy to roll around, though less convenient on stairs or in tight spaces
• Minimal on-device controls, with functions handled through smartphone app or remote

The PACE S PRO feels like something built for people who actually train. It’s not trying to be stylish or compact. Visually, it’s low-profile but sturdy, giving off the impression of a system that’s meant to be forgotten once it’s working. Having said that, I’ve had players from nearby courts come over mid-session to ask what it is and watch it in action.

The hopper is fixed into the top half of the unit and loads easily, but removing it takes more effort than I expected. It fits tightly, which helps keep it in place, but I’ve caught myself worrying about breaking it.

The machine weighs around 19 kilos, so it’s not exactly something you’d call lightweight. That said, it’s lighter than a lot of the other ball machines on the market. Compared to the Slinger Bag, which I used for a few years, this one takes up noticeably less space. It’s about half the height, so it’s easier to store.

There are wheels and a telescopic handle, so moving the PACE S PRO across flat ground is pretty straightforward. Stairs are more of a hassle because of the slightly awkward weight distribution. Getting it in and out of a car on your own takes a bit of juggling. I haven’t had any issues with the wheels, even on a few 20-minute walks to the court. But I’ve seen some users mention that the rubber on the wheels might wear down faster on rough or uneven surfaces.

Once the machine is in place, it stays put. The wide base and locking mechanism hold it steady even when firing at high speeds or with heavy spin. That makes a big difference when running more intense drills. I never had to stop and reposition it mid-session.

What I particularly like is how quiet it is during use. You can barely hear the motor running and that’s a good thing. I for one, do not want to disturb players on nearby courts with a loud piece of gear. This one is practically silent.

There’s a sound alert before each ball is launched, probably a safety feature, but that can be turned off in the app. I prefer it off. One thing I noticed is that the internal wheels keep spinning even when it’s in standby. You can stop that by switching it into Eco mode, which is easy enough to do in the settings.

On the unit itself, you can find a small control interface. The LED indicators in front are clear and easy to read, and the whole system powers on without any weird delays or boot-up issues. I usually have it ready in a couple of minutes.

Nearly all interaction with the machine happens through the app or remote, which works well. The Bluetooth connection has been totally reliable, and I can adjust drills or settings straight from my phone without needing to touch the machine once it’s powered on. The only real job is loading on the balls to the hopper.

The system also comes with a player-tracking sensor you can wear, plus two net sensors for positional feedback. But you can train just fine without using any of them. They do allow, however, for some more advanced drills. More about that later.

The design doesn’t try to stand out, but once you’ve used it, it feels solid and well put together. Everything is laid out logically, and build quality has been good so far. Still, parts like the hopper and wheels may show wear over time, so that’s something I’ll be keeping an eye on. I’ve been using it for about a month – and so far I’ve had no issues.

Technical specs

• Fast, consistent feed with up to 80 mph speed and 60 RPS spin
• Smooth motorised angle and sweep adjustments
• 8 hours of battery life on a single charge

As far as the hardware, the PACE S PRO runs on a dual‑wheel drive system that feeds balls through direct contact with the wheels. It’s capable of delivering a wide range of shots, including topspin, backspin and flat balls.

Spin intensity can be adjusted across 21 levels, with a maximum of 60 revolutions per second, which covers everything from slow looping topspin to heavier drives. The response time when switching spin types is short, so drills can simulate real rally conditions without delay or mechanical lag.

Speed can be set anywhere up to around 75–80 miles per hour. That’s more than enough to replicate real match pace. Ball frequency is adjustable from 1.5 to 12 seconds, depending on the type of session you’re after. The ball feed has been consistent in my use, and the delivery feels smooth even when pushing the higher settings.

Elevation and horizontal movement are fully motorized. You can shift the launch angle from 10 to 50 degrees for anything from low skimming shots to high lobs. Side‑to‑side movement spans roughly 50 degrees across the court, which enough to simulate both singles and doubles coverage. Transitions are fluid, and the machine keeps its aim stable between sequences.

The outer shell is reinforced plastic with internal framing that supports the motor assemblies and protects the tracking hardware. Vents are cut into the side panels for cooling. There are no exposed belts, cables or high-friction parts prone to failure. In use I did not notice any overheating or noise from cooling fans, which suggests the PACE S PRO handles heat well.

I’ve also found the ball feed reliable. After a month of use, there was only one session where there was a ball jam. And this was easily rectified by opening the side door. Problem solved in a few seconds.

As mentioned, the machine supports player tracking. It does this through a 100 Hz motion‑sensing system, which can detect position. The feature is there if you want to add reactive drills or recovery‑based training.

Battery life

Everything runs off a removable battery stored beneath the motor housing. It’s got enough capacity for multiple sessions without needing a recharge. I’ve done a couple of long workouts back to back and never had to worry about it running out. The company says you get over eight hours on a full charge, and that seems accurate. After a two-hour session, I usually drop just one of the four battery bars, so the estimate checks out.

Charging is straightforward. You just plug it in and let it do its thing. Since the battery is removable, it’s easy to handle and doesn’t get in the way. I’ve never felt limited by battery life, even when running high-speed or heavy-spin drills.

One nice touch is that you can charge the sensors directly from the machine via USB. That is handy if you’ve forgotten to refuel them at home. 

Pongbot PACE S PRO review: How to use

• App setup is quick with presets and deep custom options for advanced drills
• Smart features like AI Recovery add match-like realism
• Building long custom drills takes time, but the control over each shot is impressive

Initial setup is quick. The smartphone app pairs to the machine without fuss, and it walks you through the basics the first time you connect. Even if you’re not especially tech-savvy, you’ll be fine after a bit of poking around.

Once it’s charged, you wheel it onto the court, position the hopper and dump in the tennis balls, power it on, and control everything from your phone or the included remote. There an on-unit LED indicator lets you know when Bluetooth is active.

The app is the main control hub. You can pick from a large set of preloaded drills or start building your own. The preset drills are handy for quick sessions, and probably enough for the majority of average tennis players out there.

You can choose varying levels of difficulty, hand preference, combo interval, sequential/random sequence and more. That gives some room to tweak without going into full custom mode.

Custom drills are where this machine really stands out. You can tweak every single ball in the sequence -speed, spin, depth, placement.

It does take time to build a drill from scratch, especially if you’re setting up a 30 or 40-ball sequence. The app supports up to 45 shots per drill, and you can combine different shot types in any order. Once created, drills can be saved to your library and edited later.

You can also download drills shared by other players, and some of them are actually great. It’s a simple way to keep things fresh. The drill-sharing feature is built into the app, and you can favorite or copy any public drill into your own library.

The thing to note is that there’s a bit of a learning curve. Not because it’s hard, but because there are so many options. Especially with drills.

It took me a few sessions to figure out which features and drills were actually useful and which ones I could ignore. But once you get used to it, the basics feel straightforward. You can also simplify things by adjusting court positioning and feed delay globally, which helps match the machine’s output to your timing.

Some of the smarter modes (referred to as Smart Pace in the app), such as Recovery Trigger, are where the PACE S PRO really stands out. These are features that make the machine feel less like a ball launcher and more like a training partner.

Recovery Trigger, for example, is especially useful for footwork drills. It tracks when you’ve moved back to the centre back-end of the court and only then fires the next ball. That changes the rhythm entirely. Instead of feeding on a fixed timer, the machine reacts to your recovery, simulating real match flow. And if you’re not fully fit, you can slow the tempo down to keep the session under control.

To get this working properly, you’ll need to clip the third sensor onto yourself and set up the two net sensors that come with the system. Once everything is paired, which usually takes only a few seconds, the tracking is surprisingly accurate.

There can be a bit of a lag now and then, but overall the experience adds a strong element of realism to solo practice. It forces you to reset quickly, stay balanced and not cut corners between shots. That alone gives these drills more value than anything you’d get from a fixed feed interval.

Ramp up the difficulty level to challenge yourself even more. The thing about this is – instead of a predictable rhythm, you get a more varied pace that mimics what happens in an actual rally. It’s sometimes quicker, sometimes slower, depending on the previous ball. The whole thing keeps you alert and removes the tendency to fall into a drill pattern. It’s like training with a partner who never misses!

Together, these modes make the training feel alive. If you want sessions that prepare you for how points actually play out, these features are the ones to lean on.

Muse S Athena review: One minute review

Muse S Athena is the most advanced version of the company’s headband to date. It brings more sensors, smarter software, and a shift toward personalised cognitive insights. I’ve practically followed this product line from the start—reviewing the Muse 2 back in 2019, when real-time EEG feedback at home still felt experimental. A couple of years later I tested the Muse S, which added sleep tracking and a softer design for overnight use. Athena feels like a natural evolution of that journey.

Back then, there were two things I felt were missing. One was the ability to track cognitive performance over time, the other was real-time access to raw brainwave data. Athena delivers both.

On the surface, not much has changed. The design is familiar, comfortable, and still sleep-friendly. But under the hood, Athena is a different animal. The addition of fNIRS gives it the ability to track mental effort, not just brain states, offering a new way to measure cognitive endurance. The company upgraded the EEG and heart rate sensors, and the device now delivers more stable, more detailed biofeedback.

Daytime meditation still shines, and the new Strength session adds a sense of challenge and progress. Sleep tracking remains a strong feature, and tools like the Go-to-Sleep Journeys and Digital Sleep Pill make it easier to drift off and stay asleep. Add in brainwave visualisation, cognitive performance scores, and solid battery life, and you’ve got a headband that’s doing more than just guiding meditation.

If you’re serious about mental fitness, this is the version to get. It’s more advanced than anything else out there, both in terms of hardware and the depth of insights it delivers.

Those ready to dive in can pick up the Muse S Athena for $474.99 from the choosemuse.com website. To save 15%, use code “gadgetsandwearables” at check-out. Also, there’s a 30-day money back guarantee if it doesn’t live up to your expectations. The Gen 2 Muse S no longer appears on the site, so it’s likely being phased out. Muse 2 is still around and can be purchased for $249.99.

Muse S Athena review: Design & hardware

• Breathable stretch fabric offers a secure and comfortable fit, day or night
• Redesigned sensor pod with low-profile button and hidden LED indicators
• Includes, for the first time, fNIRS sensors
• Enhanced internal electronics deliver faster, more accurate feedback

Look & feel

At first glance, Muse S Athena looks almost identical to Muse S. The soft, fabric headband design is still here. That familiar, wraparound style remains unchanged, and if you’ve used Muse S before, Athena will feel instantly familiar.

There are a few subtle changes worth pointing out. The pod that holds the sensors has a slightly different shape, though it still snaps into the middle of the band using strong magnets. The enclosure has also been tweaked a bit.

Another tweak are to do with the multi-coloured LED lights, which are now located on the front of the pod. You’ll notice the indicators stay hidden when inactive and light up to show battery status and other basics when active. A single physical button at the bottom of the pod powers the device on or off. The main lights will turn off during sleep, but there are a two tiny LED lights on the underside that helps you confirm whether the device is running.

The strap system is still there and there was no need to change that as it works well. Clip at the back, elastic section for adjustability, soft fabric all the way around. For me it is pretty easy to get a good fit, and the strap stays in place—something that matters if you plan to use the device to track sleep through the night. With Muse devices, signal quality is import and it largely depends on proper contact with the skin.

For care, you can hand-wash the fabric band using mild, unscented detergent. Wipe the pod with a dry cloth only—avoid any chemicals or moisture. So make sure to remove the pod if you are planning any spring cleaning.

All in all, the design doesn’t stray too far from Muse S. And that’s probably a good thing. That device was already well-designed, and Athena keeps that same comfortable feel.

Under the hood

Athena takes everything Muse S did and builds on it. It keeps the same headband format and core idea of helping you train your mind and sleep better, but pushes the tech inside forward in a few important ways. This makes it feel more grown up.

The biggest new addition is a sensor called fNIRS. It tracks how oxygen flows through the front part of your brain using near-infrared light. That might sound a bit sci-fi, but the idea is simple.

EEG shows what your brain is doing and how efficiently it processes tasks through changes in brainwave activity. fNIRS, on the other hand, shows how hard your brain is working, i.e how much energy it is using. Whether you’re trying to stay focused or mentally winding down, Athena can now measure the effort behind those states, not just the end result.

With fNIRS, the idea is that with regular practice, you can train your brain to work harder and recover more quickly. A bit like lifting weights and cooling down after a workout.

The company says they’ve also improved EEG performance. The signal is now sharper and more detailed thanks to higher resolution readings and upgraded internal referencing. If you’ve used Muse before, you’ll probably notice faster signal lock and fewer hiccups during sessions.

Heart rate tracking got an upgrade too. The PPG sensor now uses three wavelengths: infrared, near-infrared, and red. This helps with more accurate heart and sleep data. On top of that, Athena uses silver-thread sensors that should hold up better over time and deliver a cleaner signal. 

Finally, they’ve also updated the wireless chip. Bluetooth LE 5.3 is faster and more stable than the older version.

As far as battery life – it is unchanged from before. You can expect around 10 hours between charges which, depending on use, is enough to get you through a few days of meditation. This sort of battery life is also good for a single night of tracking sleep. So if you intend to use the device for that purpose – you will need to charge every day.

Muse S Athena vs Muse S: the differences

Here’s a summary of the improvements Muse S Athena brings over its predecessors.

Muse S Athena review: How to use for daytime meditation

• Easy app-based setup with multiple meditation modes
• Strength session trains focus like a mental workout
• Cognitive scores offer insight into sharpness and recovery

Muse S Athena can be used for daytime meditation in much the same way as earlier models. The setup process is straightforward. Download the Muse app for iOS or Android, pair the device, and you’re good to go. Everything is controlled through the app, which is cleanly designed and easy to navigate. The default “Meditate” tab takes you straight into the available sessions.

I found the pairing process to be quick and easy. Also, I had no problems switching between my iPhone and iPad, as at times I preferred to view the results on a larger display

You’ll find the familiar options still there: Mind Meditation, Heart Meditation, Body Meditation, Breath Meditation, and Timer. Each one uses different sensors depending on the focus—whether that’s your brain, heart, breath, or stillness. They let you choose the session length and soundscape, and in some cases, you’ll get guided instructions.

The classic Mind Meditation is still my favourite. You calm your mind and the app reflects that with fewer environmental sounds. The calmer you are, the quieter it gets. Bird sounds let you know when you’re on track. You can earn badges and track progress over time. It still feels strange and a bit magical to control something with your mind alone.

The upside is that the acoustic feedback makes it really easy to catch when my mind starts to wander, and it helps snap me back to the breath pretty fast. The downside is that sometimes the sounds can be distracting on their own, pulling my attention outward when I’m trying to go inward. That said, the biofeedback does its job. It works.

Plus, if you find you would like silence while meditating – there is an option for that as well. Choose external audio sessions – without actually listening to external audio. What I like to do is, in this setting, I opt to hear the birds. They are never distracting and allow me to know when I am in deep focus.

There’s something for everyone when it comes to the types of meditations available. In fact, the variety can feel a bit overwhelming at first. It takes a few days to explore the options and figure out which ones suit you best. It’s definitely a learning experience.

And if that is not enough – you can opt for the Premium Subscription. It unlocks 500+ sessions, allows for sync with external apps and spits out some more advanced data. The good news? You don’t really need it as there’s plenty on offer without it.

What I also like are the simple explanations and tips that are sprinkled throughout the app. There really is a lot to take in and this helps to keep the learning curve manageable.

But what’s really new in Athena is how it pushes all of this further.

A new kind of feedback

As mentioned earlier – Muse S Athena introduces a new kind of feedback experience through its fNIRS sensors. These track oxygenated blood flow in your prefrontal cortex, giving you a read on how much mental effort you’re actually exerting. Alongside the standard EEG feedback, this opens the door to a new type of training: cognitive endurance.

One example is a new session type called Strength. In it, you’re asked to generate as much mental effort as possible by concentrating on the horizon in the image. Your focus propels an owl forward. The harder you push mentally, the quicker it flies.

It’s an interesting shift. Instead of just calming the mind, you’re now training it to perform—similar to how physical workouts build muscle. Your brain, like any other part of your body, needs oxygen to function. The harder you think, the more oxygen your prefrontal cortex demands. Athena measures this in real time and uses that data to assess your cognitive endurance.

It’s definitely an interesting addition. In practice, I found it works well. Having said that, I did have one session where I could not get the owl to move no matter how hard I focused. I am still not sure if that was to do with me or incorrect headband positioning.

Real-time brainwave visualisation is now part of the package

Last year, the company added a new brainwave visualization feature to its app. Which means can now see your brain activity during and after sessions, broken down into gamma, beta, alpha, theta, and delta waves. Each of these relates to a different mental state, so it gives you a clearer picture of what your brain is doing while you are meditating.

You get detailed reports after each session with this type of data, and there’s a mode where you can watch your brainwaves in real time. With Muse S Athena you can even view a livestream of your brain blood oxygenation.

All of this is definitely interesting to look at, but I haven’t found much practical use for the data yet. Maybe with more time, it’ll become more useful.

Cognitive Performance and Brain Recharge score

Worth a special mention are the Cognitive Performance and Brain Recharge scores, available exclusively on Muse S Athena. You’ll find them in the post-session reports, and they’re designed to give you a quick snapshot of how your brain is functioning that day.

Cognitive Performance uses something called alpha peak frequency, which links to focus, processing speed, and overall mental sharpness. A higher score generally means you’re more alert and better prepared for mentally demanding tasks. The system sets a baseline after a few sessions and tracks future scores against it. So this is a score that you can aim to increase over time.

Brain Recharge, on the other hand, is based on alpha power. It gives you a sense of how well-rested or mentally recovered you are—basically, your brain’s version of recovery status after a workout.

These scores are still pretty new, but I’m already finding them useful. They also signal a shift in direction: Muse is starting to move beyond just meditation and into the space of cognitive fitness. Which makes the device more useful.

On the flip side, it seems you will need a premium subscription to access these metrics. I do wish the company reconsiders and includes them as part of the free subscription – as they are very useful.

Muse S Athena review: How to use to enhance sleep

• Tracks brainwaves, heart rate, breath, and movement for accurate sleep stage detection
• Go-to-Sleep Journeys use real-time biofeedback to ease you into sleep
• Digital Sleep Pill restarts audio if you wake up, helping you drift back off

Muse S Athena isn’t just for meditation, it also tracks your sleep. You can wear it overnight or for naps, and the data it captures goes beyond what you’d get from a typical smartwatch. While I wouldn’t personally use it every night, it’s great for checking in on your sleep quality from time to time. That’s actually what InteraXon recommends.

The advantage here is that Athena S tracks brainwaves directly using EEG, along with heart rate, breathing, movement and brain oxygenation. This combination gives it an edge in identifying sleep stages accurately. The app presents everything in a clean, easy-to-read format, along with a Sleep Score after each session. It’s useful if you want more insight than what you’d get from a wrist-based device.

You’ll also find a feature called Go-to-Sleep Journeys. These are responsive audio experiences designed to help ease you into sleep. They use real-time biofeedback—your brain activity, heart rate, breath, and movement—to adjust the soundscapes and voice guidance. Think of it like a smart bedtime story that knows when you’re drifting off. You can set how long it plays, and the app fades out automatically once you’re asleep.

Comfort is better than earlier models, though it still takes a bit of adjusting to get the fit just right for overnight use. If you tend to toss and turn, the pod can shift slightly, which might end a session early. But once it’s in place, it generally stays put. For anyone curious about their sleep patterns—or dealing with sleep issues—it’s a solid tool to have on hand.

Out of curiosity, I compared sleep stats from the Muse S Athena with those from the Garmin Forerunner 955 on my wrist. The results were actually quite close. In the example above, Muse recorded a total time in bed of 8 hours and 22 minutes—just 6 minutes more than Garmin.

What really caught my attention was how closely the REM and deep sleep figures matched up, with only a few minutes difference between them. I did not expect that. The larger difference came in the light sleep and awake time categories. Muse seemed more sensitive here and did a much better job pinpointing when I was actually awake versus just in light sleep. I listen to podcasts at night and tend to have a low heart rate, which can throw off wrist-based trackers. But Muse handled this much better and felt more accurate in detecting true sleep.

Digital Sleep Pill uses smart fade technology

The Digital Sleep Pill is still here. It builds on the Go-to-Sleep Journeys with a more intelligent system that uses smart fade technology. The idea is that it not only fades out sound once you fall asleep, but it can also detect if you’ve woken up during the night. When that happens, it gently fades the audio back in—whether that’s a sleep story, ambient soundscape, or guided meditation, depending on your settings.

You can customise how long the fade lasts, the volume, and other small details. In practice, it’s a strange but interesting experience. If you’re a light sleeper or taking a nap, the audio can feel like it’s blending with your dreams. Sometimes it’s hard to tell whether you’re awake or still drifting. It’s the kind of feature that could be genuinely useful for people who struggle with falling—or staying—asleep.

A final word on safety

Safety deserves a quick mention. It’s good to be cautious with any tech that involves sensors on the head.

Muse S Athena uses passive sensors—EEG and fNIRS. That means it’s not sending any electrical current into your brain. EEG just reads the tiny voltages naturally produced by your brain’s activity. fNIRS uses low-intensity infrared light, which is non-ionizing, to measure blood oxygenation in your prefrontal cortex. Neither of these technologies is inherently dangerous. They’re also used in clinical and research settings with tight safety regulations.

So there’s no obvious reason to expect harm. Still, it’s worth being mindful of any physical discomfort, avoiding overuse, and taking breaks if you notice skin irritation or sensitivity.

Those ready to dive in can pick up the Muse S Athena for $474.99 from the choosemuse.com website. To save 15%, use code “gadgetsandwearables” at check-out.

The post Muse S Athena review: Tracking brain states, sleep and now effort appeared first on Gadgets & Wearables.

After living with the RingConn Gen 2 for four months, I’ve got a lot to say about this tiny tech companion. My previous review of the Gen 1 was just the beginning, and this latest version has brought meaningful improvements. From its refined design to a recent complete smartphone app overhaul.

The smart ring market, while still niche, has been steadily developing. Gone are the days when Oura had no competition. RingConn’s latest offering aims to build upon its predecessor’s foundation, promising improvements in health tracking capabilities, battery life, and design. As wearable tech becomes increasingly integrated into our daily lives, it’s worth examining whether these finger-worn devices can provide meaningful competition to more established wrist-based options.

In this review, I’ll explore the RingConn Gen 2 and what it brings extra over its predecessor. Still no subscription which is great, but this device does cost a little more than Gen 1. So let’s not waste any time – let’s slip this ring on and find out if it is deserving of your finger-space.

You can view RingConn Gen 2 on RingConn’s website. Code RC09 will give you a 10% discount until September 30th.

RingConn Gen 2 Smart Ring review: Design, hardware

Look & feel

Unboxing the RingConn Gen 2 reveals a device that has undergone a nice transformation in the look and feel department. While its predecessor focused on functionality, this new iteration strikes an impressive balance between form and function.

The premium packaging remains, but the ring itself now exudes a more refined aesthetic. Available in an expanded range of color options and boasting a sleek, glossy finish, the RingConn Gen 2 caters to a broader spectrum of personal styles, firmly establishing itself as a unisex device.

A notable improvement lies in its dimensions. Weighing a mere 2-3 grams, with a thickness of 2mm and width of around 6mm, the RingConn Gen 2 is a more lightweight device. While these reductions might seem minor on paper, on the finger they translate to a significantly more comfortable and discreet wearing experience.

Despite the exterior changes, the inner dimensions remain consistent with the first generation. This means users can rely on the same sizing kit. In my case I have a size 11 for both the Gen 1 and Gen 2. And they fit the same. As before, you’ll receive a complimentary sizing kit with nine options (ring sizes 6-14) before the actual ring is shipped.

The RingConn Gen 2 retains the user-friendly aspects of its predecessor, such as the ability to wear it on any finger of either hand. This flexibility is particularly useful if you find the size slightly off, as you can simply switch to a different finger. Also, for exercise you might want to opt for a tighter fit to ensure better capturing of heart rate while you are moving. What I do is I wear the ring on the index finger of my non-dominant hand, but when I exercise I move it to the index finger of my dominant hand.

One minor quibble that persists is the lack of a clear visual indicator for correct orientation. The company maintains its tactile positioning method. While this works, a more obvious marker would be welcome for quick, at-a-glance positioning checks. In an ideal world, the green and red lights need to be on the palm side of your hand. But I rarely checked this and found that the ring still worked perfectly well.

The enhanced water resistance, now up to 100 meters (328 feet), adds an extra layer of durability and peace of mind for active users. Whether you’re washing dishes, swimming, or engaging in water sports, the RingConn Gen 2 is built to withstand it all.

Durability has also seen an upgrade. The glossy finish not only enhances the ring’s aesthetic appeal but also proves more resistant to scratches. This addresses one of the few criticisms of the original model, where some users reported visible wear over time. However, for those seeking extra protection, the company still offers optional ring protectors as an add-on accessory.

A final word of note, the device does not incorporate a vibration motor. In fact, there are hardly any rings that offer this type of functionality due to size constraints.

Under the Hood

Below the surface, the RingConn Gen 2 builds upon its predecessor’s solid foundation. At its core, the device retains the infrared, red, and green sensors, but now features an enhanced PPG sensor for more accurate heart rate monitoring. The accelerometer is a more sophisticated 3D version, promising improved motion tracking.

These enhancements, coupled with the upgraded temperature sensor, enable the RingConn Gen 2 to introduce Sleep Apnea tracking – a valuable feature for users concerned about sleep-related breathing disorders.

So its an iterative upgrade as far as internal components. No new sensors, just improvements in existing ones.

Connectivity remains via BLE 5.2, maintaining the efficient Bluetooth connection of the original model. No Wi-Fi support. The EMF-Safe technology and airplane mode are still present, catering to users who prioritize minimizing electromagnetic exposure.

The week-long on-board storage capacity is still there. I tend to sync the device to the phone every day, but you do have a 7 day window before you start losing data.

More than 10 days between charges!

For me, one of the most impressive upgrades in the RingConn Gen 2 is its significantly extended battery life. It is truly impressive.

While the original model offered a respectable 7 days of use on a single charge, the new version pushes this to an outstanding 10-12 days of continuous operation, depending on settings. This enhancement in battery longevity is attributed to advanced optimizations, including a more efficient MCU chip and improved algorithms, which have reportedly reduced power usage by an impressive 259%.

In real-world testing, the difference is substantial. The RingConn Gen 2 loses approximately 10% of its battery charge per day, making it the ring with one of the longest-lasting batteries in the market. This extended life translates to a more convenient user experience, reducing the frequency of required charges and allowing for more consistent, uninterrupted tracking.

Having said that, I did notice battery life of my Gen 1 device deteriorated somewhat after about a year of use. Unfortunately, this is a common issue with smart rings. In the four months that I’ve been testing the Gen 2 device, its capacity remained unchanged.

The charging case, which proved convenient in the first generation, becomes even more valuable with the Gen 2 model. When combined with the ring’s improved battery life, users can now enjoy more than 150 days of use between case charges. Which makes RingConn Gen 2 an excellent choice for frequent travelers or those who prefer minimal device maintenance.

Technical specs: RingConn Gen 2 vs Oura Ring

Now, let’s examine how RingConn Gen 2’s technical specifications compare to a well known name in this space – the Oura Ring. As we’ll see, RingConn Gen 2 has made nice strides, in some areas surpassing its more renowned competitor.

Both rings are crafted from similar materials and share comparable dimensions. However, RingConn Gen 2 has managed to reduce its weight and size, now weighing 2-3 grams compared to Oura’s 4-6 grams. This makes RingConn potentially more comfortable for long-term wear.

In terms of battery life, RingConn Gen 2 has taken a significant lead. While both companies previously advertised similar battery life, RingConn Gen 2 now boasts an impressive 10-12 days of use on a single charge, compared to Oura’s claimed 4-7 days. Moreover, RingConn Gen 2’s portable charging case extends its usability to over 150 days between case charges, a feature Oura doesn’t offer.

RingConn Gen 2 has also improved its water resistance, now matching Oura with protection up to 100 meters. This eliminates the previous advantage Oura held in this area.

Functionally, RingConn Gen 2 maintains its edge with 24/7 tracking of heart rate variability and blood oxygen, features Oura only offers during sleep. RingConn Gen 2 has also added Sleep Apnea tracking, further differentiating itself from Oura.

The cost difference between the two should also be mentioned. While RingConn Gen 2’s price remains competitive, there is no monthly subscription. For Oura, in addition to the purchase coast there’s the on-going addition of its $6 monthly subscription fee. Let’s hope RingConn retains the non-subscription model as I feel this is a big selling point.

RingConn Gen 2 Smart Ring review: Features

Having been such a fan of the first gen device, I was looking forward to testing out its successor. The changes in functionality are not enormous, but there is an important addition.

The journey of RingConn from a crowdfunding success to a established player in the wearable tech market is nothing short of remarkable. Their Kickstarter campaign for the Gen 2 model has raised over $4 million, making it most crowdfunded smart ring ever. To remind, the company raised around $1.2 million in its campaign for the original device.

What sets RingConn apart is not just their great product, but their commitment to continuous improvement. There are no false promises, a common issue with crowded campaigns. There really are some horror stories out there with companies over-promising both in terms of features and delivery dates. No such issues here.

What’s more, RingConn has consistently demonstrated responsiveness to user feedback, regularly releasing software and firmware updates. And they now have a established track-record with the first gen device. Their active presence on social media platforms, particularly their Facebook group, provides a direct line of communication with users.

Using the ring

The setup process for the device remains straightforward. After downloading the app and pairing the ring, you’re ready to go.

The Gen 2 builds upon the strong foundation of its predecessor, focusing on recovery statistics and sleep analysis. However, it now offers slightly better accuracy thanks to upgraded sensors. The device tracks heart rate, heart rate variability, sleep patterns (including nap duration, sleep stages, and efficiency), skin temperature while you sleep, SpO2 and stress levels throughout the day.

The companion app has undergone significant refinements since the original launch. The most recent update, that landed a few weeks ago, represents a complete UI overhaul, plus AI features are sprinkled throught. The refreshed app introduces a five-tab structure that combines detailed metrics with personalized guidance.

The Trends section maintains RingConn’s strength in detailed statistical analysis. Here you can find comprehensive health metrics for users who prefer sifting through in-depth data. Group stuff into weekly, monthly or annual views – as per your liking. Overall, I would say the interface is intuitive, much more so than with the previous version of the app.

The Vital Sign Abnormalities feature is worth a special mention. It works in the background, and if the algorithms spot something in your data that is amiss – the app will warn you. This can be useful as an early alert, for example, if you’ve caught a fever or another illness. Or are simply too fatigued.

While the wealth of data provided can sometimes feel overwhelming, the addition of “scores” for various metrics helps to quickly gauge your daily performance. The app still presents a multitude of charts for each data point, which might be excessive for some users. However, the company has made strides in making the interface more user-friendly, striking a better balance between comprehensive data and accessibility.

I do like the new AI features and think they are a nice addition. There is a Plan section that leverages artificial intelligence to create customised health recommendations based on historical data. Along with this you can find a chatbot features allowing you to query your health data. This, however, still appears to be work in progress – and is currently limited to a set of predetermined questions.

Integration with Apple Health and Google Fit remains, ensuring your RingConn data can be part of a broader health tracking ecosystem.

Sleep Apnea tracking

A standout feature of the Gen 2 model is the introduction of Sleep Apnea tracking, leveraging the improved sensors to provide potentially life-saving insights. This is an extra over the first generation model which doesn’t have the feature.

Sleep Apnea tracking works in the background. There is nothing really for you to do except switch on the comprehensive assessment option. And ensure your ring has more than 30% battery life and sync data once a day. The device offers a three-night average assessment alongside the single-night option.

When you wake up in the morning, tap the sleep apnea section to allow the data to sync. I found I did not have any issues, which was good to know. But it is something that I plan on using from time to time, just to make sure.

Accuracy of activity metrics

The step counting accuracy of the RingConn Gen 2 remains impressive. When compared to both manual counting and data from other reliable devices, the ring’s step count was consistently within a 3-4% margin of error.

However, the device still faces challenges in accurately tracking heart rate during exercise. In my testing, I noticed a significant shift in the heart rate data compared to the first generation device.

While the original RingConn tended to underestimate heart rate during physical activity, the Gen 2 model consistently overestimates both average and maximum heart rates. I conducted several test runs, comparing the RingConn Gen 2 data with a reliable chest strap heart rate monitor, and found that the ring consistently reported higher values.

It’s worth noting that measuring heart rate from the finger during intense physical activity remains a challenge for most smart rings on the market. The constant movement and reduced blood flow to the fingers during exercise can interfere with the optical sensors’ ability to accurately detect heart rate.

Despite the exercise issue, the RingConn Gen 2 still provides valuable insights for general activity tracking and recovery metrics. Its strengths lie in sleep tracking, resting heart rate monitoring, and overall daily activity assessment. For those primarily interested in these aspects of health tracking, the RingConn Gen 2 remains one of the best options in the smart ring market.

Accuracy of recovery stats

Over the past year my wearable tech combination is a Whoop on my upper arm, a Garmin Forerunner 955 on my wrist and a RingConn on my finger. Now I’ve swapped that with RingConn Gen 2.

Below is a table that illustrates the correlation between Garmin/Whoop, Garmin/RingConn, and RingConn/Whoop with respect to nightly resting heart rate and heart rate variability. This is for a three week period.

Similarly to what I found with the first gen ring, the second generation is much closer in its results to Whoop than it is to Garmin. The Garmin, while similar in resting heart rate, significantly differs in heart rate variability.

In terms of sleep length, not much difference between the three devices. While there are day to day discrepancies, they tend to even out in the medium term.

As far as absolute values, Whoop and RingConn pegged me at between 51 and 52 bpm for my resting heart rate. Garmin was a few beats per minute lower.

For average value of heart rate variability during this three week period, RingConn was somewhere in between the Whoop and Garmin. It clocked me at 37 ms, compared to 33ms on Whoop and 46ms on Garmin. This difference is likely attributable to variations in the methodologies employed to calculate this metric.

RingConn Gen 2 Smart Ring review: The bottom line

The RingConn Gen 2 represents a nice upgrade over the original. Instead of reinventing the wheel, the company opted to make a good device even better, by slapping on some iterative improvements.

The ones I noticed most are the sleaker more lightweight design, along with awesome 10+ day long battery life. Beyond that you get more accurate sensors and the addition of Sleep Apnea monitoring.

While the device still struggles with heart rate accuracy during intense exercise, its strengths in sleep tracking, recovery metrics, and daily activity monitoring are undeniable. The absence of a subscription model and competitive pricing further add to its appeal.

For those new to smart rings the RingConn Gen 2 offers excellent value. It might even be worth an upgrade for those with the original device. Its combination of features, battery life, and user-friendly app make it a worthy alternative to more expensive competitors. As the Gen 1 version has largely the same features, that one might also be a good option as it is likely to see a fall in price in the coming months.

You can view RingConn Gen 2 on RingConn’s website. Code RC09 will give you a 10% discount until September 30th.

The post RingConn Gen 2 Smart Ring review: Four months of wear, here’s the verdict appeared first on Gadgets & Wearables.

There are various devices out there that promise to help manage stress and anxiety. Among these, Pulsetto stands out as a vagus nerve stimulator designed to biohack your parasympathetic nervous system, offering an intriguing approach to achieving calm and balance in our increasingly hectic lives.

This compact, wearable gadget claims to deliver significant benefits with just a few minutes of daily use. By stimulating the vagus nerve, Pulsetto aims to activate the body’s natural “rest and digest” response, potentially reducing stress, lowering anxiety, and promoting better sleep. 

In the past, this would not have been the type of device I would review, as I typically stick to more straightforward wearable gadgets such as smartwatches and fitness trackers. I have tried yoga and meditation to manage stress occasionally, but never quite stuck with either practice.

Pulsetto piqued my interest because well-known entrepreneur and venture capitalist Bryan Johnson uses it. He has made himself a guinea pig for pioneering longevity research. Amongst other things, Johnson recommends vagus nerve stimulation for lowering stress, improving mood, enhancing digestion, and reducing body inflammation. What also had me excited were Reddit posts from users claiming large increases in heart rate variability by using Pulsetto.

Pulsetto review: What does it do?

Put simply, Pulsetto is a vagus nerve stimulator that aims to activate the body’s natural relaxation response. For those not in the know, the vagus nerve is the longest cranial nerve in the body. It consists of a vast network of nerve fibers connecting the brain to various organs including the heart, lungs, and digestive tract. The vagus nerve plays a crucial role in regulating the parasympathetic nervous system, often referred to as the “rest and digest” system.

Vagus nerve stimulation (VNS) has been studied for decades, with FDA-approved devices being used to treat epilepsy and depression since the 1990s. Pulsetto brings this technology into a more accessible and budget-friendly format, leveraging similar principles to clinical VNS treatments. The device works by sending gentle, non-invasive electrical pulses to stimulate the vagus nerve for just a few minutes each day.

Stimulating the vagus nerve has been shown to have a range of potential benefits. These include reducing stress and anxiety, improving sleep quality, enhancing digestive function, regulating heart rate, and potentially alleviating symptoms of certain medical conditions. Studies generally show that vagus nerve stimulation is safe, with potential side effects being temporary and including hoarseness, coughing, and shortness of breath.

Traditional methods of achieving vagus nerve stimulation include mindfulness meditation, deep breathing exercises, and yoga. However, these can be challenging to maintain consistently.

Pulsetto offers a potentially more convenient alternative for daily use, making it an attractive tool for biohackers and those seeking to improve their overall well-being. The device is FCC certified, ensuring its safety for well-being use. It employs ultra-low radiofrequency energy (ULRE) via Bluetooth, designed to safely interact with the body.

By influencing various body functions through daily stimulation, Pulsetto aims to provide a natural way to manage stress and promote health. There are alternative form factors such as ear devices you can buy for this sort of thing. But neck versions are said to be more effective.

Pulsetto review: Design

With the science lesson out of the way, let’s move on to the review. Out of the box Pulsetto loosely resembles a pair of oversized headphones. But the device is not meant to be worn like headphones. Instead it goes around your neck.

The whole thing is compact and lightweight, measuring just a few inches in length and weighing only a few ounces. It has a sleek, minimalist design is reminiscent of modern tech accessories, featuring a smooth, finish that feels comfortable in the hand.

The main body of the Pulsetto houses the electrical components and battery, with two round metal electrodes protruding from each end. These electrodes are designed to make contact with the skin on your neck, where they deliver the gentle electrical pulses to stimulate the vagus nerve.

The device features a single button for operation, keeping the user interface simple and intuitive. A small LED indicator provides visual feedback on the device’s status.

Pulsetto comes with a charging cable and a compact carrying case, making it easy to transport and use on-the-go. The charger is a standard USB-C cable which I prefer to proprietary ones. I you lose it, just use any other standard USB-C cable. With regular daily use, you should be able to get about a week between charges. When the indicator turns blinking green, you need to recharge. The app will also notify you.

All things considered, Pulsetto is a well designed gadget. I would say, it’s even discreet enough to be used in public without drawing attention to yourself. Its ergonomic shape and small size allow for comfortable handling and positioning during use. And battery life is pretty decent.

Pulsetto: How to use

Using the Pulsetto vagus nerve stimulator has become an integral part of my daily routine, particularly in the evening. You are meant to start by applying an electrode gel to both sides of your neck. The gel is included in the box.

While this step can be a bit messy, I’ve found it’s essential for optimal performance. I usually just use a small dab on each side and wipe it off after use. So it’s not a big deal. I don’t think you can use Pulsetto without the gel as the sensation would be uncomfortable.

Next, you are meant to place the device around your neck where the vagus nerve is accessible – while you are in a sitting position. Adjust the size so that it fits snuggly. Make sure Pulsetto is switched on and pair it with the accompanying app on your smartphone.

Once connected, you need to choose a program. There are various options available, including stress reduction, anxiety relief, burnout and sleep improvement. Some premium programs are also available with a subscription. But you have all the basics even without that.

The connection to the smartphone is pretty seamless. In the nearly month of use, I only encountered a problem once. Restarting the phone resolved it.

Once the program starts you will feel a gentle tingling sensation on your neck. It is actually difficult to describe – a bit like a low level current of electricity against your skin.

I’ve used intensities up to level 8, but I’ve noticed that the sensation can vary from day to day. What is a 5 one day may feel different the next day. So I always adjust as needed. Anything above 8, I feel, would be too much. What I like is that you can increase or decrease the intensity while you are in the middle of a programme.

Most sessions last between 4 to 10 minutes, making it easy to fit into even the busiest schedule. It certainly takes less time than a meditation or yoga session!

And you should follow the instructions the app spits out. For example, if you’ve done a sleep program, you need to allow a certain amount of time to pass before you can use the device again. It is a safety precaution. You should not use Pulsetto too often, too long or too close together.

There’s also the option to switch on soundscapes during a programme. The Pulsetto smartphone app has a variety that can be found in the sound library. I was perfectly fine without them as the sessions are fairly short.

You are meant to use it regularly for best results

For best results you should find time to use the device twice daily. I did some days, but was not religious about it.

For me, Pulsetto is most useful when used before bedtime. It helps me fall asleep faster and stay asleep throughout the night. The effect is actually quite noticeable. I know myself and the sleep quality improvement is not random. It is clear and consistent. Not only that, but my Garmin watch started telling me I had good sleep sessions – a rarity in my world. So I had empirical data demonstrating the device actually works.

I believe it calms down my nervous system and racing mind. After using the device, you feel a sense of calm and relaxation, similar to the effects of intense exercise combined with meditation.

Having said that, I haven’t personally observed changes in my heart rate variability as reported by my Whoop and Garmin watch. Perhaps if I use it more consistently, the effect on HRV will come.

As mentioned, there are Reddit posts on users experiencing large spikes in HRV after using the device. So the effectiveness of Pulsetto does vary among users. The company says results can take anywhere up to a month to show. Those with severe symptoms or elderly individuals with significant imbalances may notice benefits sooner. Healthier individuals might take longer to experience the effects. For me, the improvement in sleep occurred after first use.

What I was careful not to do, though, is use the device before driving. It does make you feel a bit groggy and very chilled. The same is the case for exercise. I tended to avoid using it before heading out for runs. If you are in a calm and meditative state – it is unlikely you are going to go faster and longer.

Breathing exercises

Beyond this, the app also helps you relax with breathing exercises. There’s a few different ones to choose from such as Unwind Your Thoughts, Stress Dissolve and Panic Deflector. Think of this as a guided meditation or breathing session.

Choose the duration and you will be guided when and how to inhale, exhale and for how long to hold your breath. It’s a nice add-on to the primary functionality. The app also allows you to combine this with vagus nerve stimulation – so you can do both at the same time.

Pulsetto review: The Verdict

Pulsetto offers an intriguing and effective approach to managing stress and improving sleep quality through vagus nerve stimulation. While it may not be a magic solution for everyone, my personal experience with the device has been positive, particularly in terms of enhanced sleep quality and overall stress reduction.

The device boasts a compact, lightweight design with a sleek, minimalist aesthetic that’s user-friendly and easy to operate. The app interface is straightforward, though applying the electrode gel can be seen as a slight negative. Pulsetto offers various programs for different needs, including stress reduction and anxiety relief, with short 4-10 minute sessions that are very easy to incorporate into daily routines.

In terms of effectiveness, I had immediate improvements in sleep quality. While I didn’t observe the changes in HRV that some users have reported, the positive impact on sleep and stress levels was clear and consistent. It’s worth noting that results may vary among users, and it may take up to a month to experience full benefits.

Pulsetto isn’t a replacement for traditional stress-management techniques like meditation or yoga, but it offers a quick, convenient alternative for those struggling to maintain consistent practice. Its effectiveness, combined with its ease of use, makes it a worthy consideration for anyone looking to improve their stress management and overall well-being.

Frontier X2 review: Design & hardware

At first glance, the Frontier X2 appears identical to its predecessor. The core unit, which houses the device’s electronics, maintains the same (73 x 24 x 13 mm) dimensions and weight (25 grams), ensuring a comfortable and familiar feel. Elastic chest straps, one blue and one black, are also included, allowing you to swap them out as needed.

A closer inspection reveals a subtle change: the physical button on the core unit, previously red, now sports a vibrant blue hue. This minor alteration serves as a visual cue to differentiate the second-generation device, while maintaining a consistent design language. Beyond that I didn’t spot anything different in the looks department.

The sleek packaging also contains a Micro USB charging cable and a quick start guide. Next to them you’ll find a one-year warranty and 14-day risk-free trial, giving you a bit of time to test out the device.

If you’ve ever worn a heart rate chest strap, Frontier X2 is no different. Attaching the core unit to the strap is a simple process: position the unit onto the pins in the strap and press firmly until it clicks into place. The adjustable strap mechanism allows you to easily achieve a comfortable fit just below the centre of your ribcage. The strap holds everything firmly in place, even during vigorous activity. 

The Frontier X2 core unit may not have the most modern design, but don’t let this fool you. There is some very advanced tech inside. Plus everything feels very robust, like it could easily survive a few accidental drops.

As far as water-resistance, the device is good for submersion up to 1.5 meters. So yes, you can even use it when swimming.

A simple interface with a questionable screen

The device’s operation is streamlined with a single physical button located on the underside. This button powers everything on/off, starts/stops activity tracking, and logs event markers. Additionally, a strip of LEDs on the opposite end provides status updates through different colors, indicating pairing status, power on/off, and more. The overall control scheme is intuitive and user-friendly.

One big difference between Frontier X2 and standard chest straps is the addition of a small screen on the core unit. Like on the first generation, the screen is primarily used to display battery life, mode status, and a post-workout summary of your activity. 

Not this might seem like a strange addition, and it is. I personally can’t see the point. Don’t get me wrong – this is more of an observation than a negative.

The screen’s positioning across the front of your chest makes it extremely difficult to read during exercise. Plus the strap will likely be sitting below a shirt or other garment. Even if you were looking at yourself in the mirror, it would not be easy to make out what the screen is displaying. If Frontier releases a third generation device, it may be an idea to do away with the screen altogether – as this may improve further the already excellent battery life.

Enhanced connectivity

The Frontier X2 offers a few different connectivity options for tracking your workouts:

1. Smartphone app: The method involves pairing the Frontier X2 with the accompanying iOS or Android app. This allows you to start, stop, and monitor your workouts directly from your smartphone. The device utilises Bluetooth for communication. You can also get a live feed of your ECG, as a separate function.
2. Standalone mode: Alternatively, you can use the Frontier X2 independently during your exercise session and sync the data to your smartphone afterward. This option is ideal for those who prefer to minimize distractions during their workouts. Or when its not practical to carry your phone with you.
3. External heart rate monitor: This one is my favourite. The Frontier X2 can also function as an external heart rate monitor, transmitting your heart rate data to compatible third-party devices, including Garmin, Polar, Wahoo, Zwift, and Peloton products. In parallel, it also captures all the same data as in standalone mode and saves it to the on-board memory.

Notably, the Frontier X2 can connect to multiple devices simultaneously, supporting up to two third-party devices in addition to the smartphone app. Although most users may not require this level of connectivity, it’s a valuable option for those who utilize multiple fitness trackers or platforms.

It’s important to note that the device, like its predecessor, does not support ANT+ connectivity. But it now has Bluetooth 5.0. Which is an improvement over the original as it allows for 3 times the speed and greater range. There are also faster updates for heart rate on connected devices.

Battery that won’t miss a beat

Battery life is excellent. On a single charge there is enough juice for continuously recording for up to 24 hours. So a bit of an improvement over the first generation. If you exercise every day for one hour with the chest strap, you’d only need to charge it once every two weeks. A full charge can be achieved in just 45 minutes.

During my testing, I found that topping up the device every 4-5 days for about 20-30 minutes was more than sufficient to keep it at 100%. Charging is done via a standard Micro USB cable, which is convenient for replacing if lost or damaged. This familiar charging method adds to the overall user-friendliness of the Frontier X2, ensuring you can easily keep it powered up and ready for your next workout.

Frontier X2 review: Functionality

Setup & use

Setting up the Frontier X2 is a breeze. Simply download the Fourth Frontier app and create an account. Then pair your device. Your login credentials will also grant you access to the web dashboard, which offers a more comprehensive view of your data. For your initial workout, try tracking it directly through the app.

Attach the strap to your chest, turn it on, and the screen will display the time, a summary of your last workout, and battery and memory levels. Remember to dampen the sensors on the strap and your skin before each workout to ensure accurate data collection from the start. It is not absolutely necessary, but it does help. This practice is actually beneficial for most heart rate chest straps.

The smartphone app is very easy to use. Along the bottom are a few tabs. One is Home, which takes you to a screen with an overview of your stats, recommendations and selected forum posts. Next to that there is a tab that takes you to a feed of your workouts, a small plus sign which you need to click on in order to start manually activity tracking, a Community tab and a Settings tab.

Activity tracking – customising heart health alerts

Using your phone as a display is not very practical for certain types of exercise – such as running. But it can be a good option for those cycling, rowing and engaging in other types of activities. For runners, I suggest they use another option. Simply start and end the session by double-pressing the button on the device itself. As mentioned, everything will be stored on the onboard memory and you can leave your phone behind. Then simply sync Frontier X2 with your smartphone later on.

Those that want to initiate a workout via the app can do so via the small plus sign. After choosing your activity type (from the long list that includes run, cycle, walk, strength, etc.), you can customize alerts for Cardiac Strain and Breathing Rate by setting upper and lower limits. Or leave the default values. Exceeding these thresholds during your workout triggers a double buzz notification. 

Fourth Frontier emphasizes breathing rate, considering it equally important as heart rate during exercise, a claim open to debate. But the undeniable value of heart information is where Cardiac Strain enters the picture.

This proprietary metric, medically known as ST depression, measures oxygen deprivation in heart muscles. Consistently high values can damage heart cells and should be avoided, as they may lead to fibrosis or arrhythmias over time. Frontier X’s real-time buzz alerts warn users when they cross into this unhealthy territory.

Additionally, the Cardiac Rhythm feature uses ECG data to detect deviations, displaying a post-exercise pie chart of time spent in Blue (Normal Sinus Rhythm), Yellow (Other Rhythm), or Gray (Not Interpretable) zones. More detail is available in 20-second interval charts, flagging any suspicious changes.

This is the type of data that you will not get from any other heart rate chest strap. At least not in this easy to understand fashion.

There’s also an optional Share link. Click on that and you’ll get a link you can send to someone that will allow them to keep an eye on your stats in real time.

Once you’ve saved your preferences, click start and allow a few seconds for the first readings to appear.

For running or walking, the Frontier X2 smartphone app displays metrics such as Effort, Strain, Heart Rate, HRV, Training Load, Cadence, Distance, and Pace. The other sports are slightly tweaked versions of the same. I don’t think there’s much of a difference.

I put the Frontier X2 head-to-head with a Polar OH1 chest strap and the results were pretty impressive. The heart rate stats matched perfectly, so I’m confident that the Frontier X2 is the real deal when it comes to heart rate accuracy.

A useful feature is that a single press of the device’s physical button allows you to mark significant events during your workout. This could be anything from a sudden strain or difficulty breathing to simply starting a new lap. So that a feature to be aware of as it might be useful to you.

Post-workout stats

After your workout, give Frontier X2 a few moments to sync its treasure trove of data to your smartphone app. Then get ready to dive into a world of stats and graphs that go way beyond what you’d see with a typical heart rate monitor.

Training Load

To start off you get a weekly Training Load based on the time spent in different Breathing Rate zones. Its like a points system and you can view a chart of your progress. Fourth Frontier claims this method of calculating training load is more precise than using heart rate or power zones, citing research to back it up. For example, Breathing Rate is not effected by factors such as caffeine, lack of sleep, temperature, humidity and stress. All of these can cause distortions with heart rate based training.

Heart health and more

Click on the History tab for a list of all your individual workouts. Tap on any workout to get more detailed metrics. This is where it gets more exciting.

Sure, you’ll get the usual stuff like heart rate and calories burned, but it’s the unique metrics like ECG trace, Cardiac Strain, Cardiac Rhythm, and Body Shock that really set Frontier X2 apart. These are the type of insights you won’t find on “traditional” heart rate chest straps.

Things such as Cardiac Strain and Cardiac Rhythm give you an assessment of your heart health during exercise. For me, there were only a few irregularities that were flagged up – nothing to worry about.

The ECG trace, on the other hand, presents your activity in 20-second segments. Zoom in to pinpoint any flagged irregularities in your heart rhythm, or to examine the markers you set during your workout, which appear as vertical black lines on the graph.

Body Shock, in particular, deserves a shoutout. It measures the impact of each foot strike and letting you know if your form is putting undue stress on your knees or other joints. You’ll see how this impact changes throughout your workout, so you can catch any deterioration in your technique before it leads to injury.

The app itself is a data lover’s dream, with detailed charts and tables. You can even compare different workouts side-by-side to track your progress over time. And if you triggered any alerts during your workout, they’ll be waiting for you in the app, along with a plain-English summary of your overall performance and personalised recommendations for your next session.

Using the website dashboard

If you’re a data geek, the Frontier X2’s website dashboard is your playground. It takes everything great about the smartphone app and supercharges it, giving you a bigger, bolder view of your fitness journey. With its larger screen, you can dive deep into the wealth of stats and zoom in on details.

IBut the dashboard doesn’t stop there. It also throws in the Health Trends section, a feature that tracks your progress over time and uncovers hidden patterns you might have missed on the smaller screen.

Initially, the Health Trends section might seem a bit bare, but stick with it. After a couple of weeks of training, it’ll start to paint a picture of your fitness trajectory. Having said that, I do feel its more of a nice to have than a must have as it didn’t really help me with any groundbreaking realisations. But I am keeping an eye on it.

Using Frontier X2 with a 3rd party device

Pairing the Frontier X2 with a third-party device via Bluetooth, like my Garmin Forerunner 955, is another option. It works just like any other heart rate chest strap. But remember, data flows one way: from the Frontier X2 to your Garmin, not the other way around.

Since my original review was published Fourth Frontier have introduced functionality which allows users to connect their Garmin account directly with the Frontier X2 smartphone app. This is useful as it allows for syncing of GPS maps of your exercise from your Garmin account to the Frontier app and web dashboard.

Turning on the Frontier X2 doesn’t automatically start tracking, though. You’ll need to double-click the physical button to kick things off. So, with my Garmin, I switch on the Frontier X2 and wait for the connection to Garmin confirmation, get a GPS signal on the watch, and then double-click the Frontier X2 to start heart rate tracking. After a few seconds, I’ll start seeing the data on my Garmin, and then I start the workout. It might seem like a few extra steps, but it quickly becomes routine.

Beyond that there is nothing to do. When you finish your workout, you’ll need to end the activity both on your Garmin watch and on the chest strap (another double-click). Garmin has the heart rate data saved, while Frontier X2 has heart rate and all the other tracking data in its memory. So you can sync that afterwards to the Fourth Frontier smartphone app for detailed insights.

Apple Watch users get a special treat: a dedicated Frontier X2 app for choosing activities and controlling the device, plus real-time display of multiple Frontier X2 metrics right on the watch. It’s a feature I’m hoping to see on Garmin and other platforms soon.

Continuous 24 hour ECG recording

Beyond tracking workouts, you can also use Frontier X2 as an ECG recorder. The special mode is triggered from the smartphone app. It is where the device crosses into purely a health wearable.

Current ECG devices, primarily watches and handheld units, are not ideal for exercise as they require the user to be stationary and provide lower quality data due to recording from the finger or wrist instead of the chest. Additionally, they typically only capture short ECG segments, unlike the Frontier X2, which allows for longer continuous recordings.

Frontier X2 is a single lead ECG. But it more closely resembles the output from the V5 lead of a medical 12-lead ECG measurement. The ECG signal is sampled at 125Hz intervals which equates to once every 8 milliseconds, which is quite good. That’s particularly important considering this is the metric that is used to evaluate your heart health.

When you finish the recording, you can tap into a detailed evaluation of the readings.

There is no way for me to confirm the actual accuracy of ECG recordings. But I do have a few devices in my arsenal that can capture ECG – and the waveforms look very similar.

“In studies comparing the Frontier X2 to a Holter Device and 12 Lead ECG, the Frontier X2 picked up all abnormal heart rhythm changes (arrhythmias) found by Holter and 12-Lead ECG, and adequately measured heart rate and QTc changes.” states Fourth Frontier on its website.

For those that want to share their recording with a doctor or a loved on, Frontier X2 comes with an option to send remote readings. You’ll get a link which you email to the other person – once they click on it they’ll be able to follow your ECG in real-time. By the way, you get this same option when starting a workout via the smartphone app.

Frontier X2 review: Pros & Cons

Frontier X2 has a lot going for it. But it also has a few cons. Let’s list them.

Pros:

• In-depth data: The Frontier X2 dives deep into physiological metrics, offering far more than a standard heart rate monitor. ECG, Cardiac Strain, Cardiac Rhythm, and Body Shock are just a few of the unique insights you’ll gain. They add a whole new element to your activity tracking.
• Versatile use: Whether you’re using it independently, with the smartphone app, or paired with a third-party device like a Garmin watch, the Frontier X2 adapts to your preferences.
• Accurate tracking: Heart rate data is comparable to trusted brands like Polar, ensuring reliable tracking for your workouts.
• Workout insights: Body Shock analysis helps you identify potential injury risks in your form, while post-workout summaries and personalized recommendations guide your training.
• Real-time alerts: The device buzzes to warn you of excessive strain or unusual heart rhythms, allowing you to adjust your workout intensity as needed. You might be suffering from heart rate issues that you might not be aware of. The idea of this wearable is to warn you if this is, indeed, the case. It also warns if your breathing rate goes up to much during exercise, as this can be damaging to your lungs.
• Long battery life: A single charge lasts up to 24 hours of continuous recording, ensuring you won’t run out of juice during extended activities.
• User-friendly app and dashboard: Both platforms offer easy navigation and in-depth analysis, with the web dashboard providing even more powerful tools for data exploration.
• 24-hour ECG monitoring: Unlike other ECG devices, the Frontier X2 allows for continuous recording, giving you a comprehensive view of your heart health throughout the day.

Cons:

• Price: The Frontier X2 is a premium device with a price tag to match – particularly if you compare it to a standard chest strap. This makes it a significant investment for most users.
• Screen usability: The screen on the core unit is difficult to read during exercise and may not be necessary for all users.
• Learning curve: While generally user-friendly, the device’s advanced features and data may require some time to fully understand and utilize effectively.
• Limited third-party integration: Although the Frontier X2 can connect to multiple devices, some features, like real-time display of metrics, are only available on Apple Watch.
• No ANT+ connectivity: The device relies solely on Bluetooth for communication, which may be a drawback for users who prefer ANT+ compatible devices.

While the Frontier X2 delivers on its promises, I’m holding out hope that Fourth Frontier will release an armband version in the future, offering a more convenient alternative to the chest strap. And does away from the display – I feel there’s no need for it.

To help you understand how the Frontier X2 stacks up against other heart rate monitors and ECG devices, check out this handy comparison chart created by Fourth Frontier. It clearly outlines the key differences between each type of device,giving you a clear picture of what the Frontier X2 brings to the table.

Frontier X2 review: The bottom line, is it worth it?

Frontier X2 isn’t for everyone. Its premium price might be a dealbreaker for casual users or those interested only in basic heart rate tracking. However, if you’re serious about understanding your body, training smarter, and potentially identifying underlying health issues, the Frontier X2 is a worthy investment. Its wealth of data, unique insights, and real-time alerts provide a level of detail that few other wearables can match.

While older individuals may find particular value in its features, the device’s appeal isn’t limited by age. Anyone curious about their heart’s performance during workouts can benefit from the detailed data and real-time feedback it provides. This includes athletes seeking to optimize their training, individuals recovering from cardiac events or injuries, or simply those who want a more comprehensive understanding of their overall health.

Frontier X2 Use code FFGNW25 at checkout for a 30% discount

You’ll get answers to questions such as: Am I overexerting my heart and lungs? Can I push harder? The thing even tracks the impact on your joints with each foot-strike, potentially preventing injuries. For those who push their limits during workouts, the reassurance of staying within safe zones is invaluable.

Then there’s the live ECG function. It adds another dimension, valuable for those recovering from heart issues or simply curious about their heart health. 

Ultimately, it boils down to what you’re after.

If heart rate tracking is all you need, a regular chest strap will do the job just fine, and at a fraction of the cost. But if you’re curious about other aspects of your health during exercise, the Frontier X2 goes above and beyond a simple heart rate monitor. It’s not a medical device, but it packs a punch when it comes to information and insights.

Price, where to buy

Frontier X2 can be purchased on the company’s website. Use code FFGNW25 at checkout for a 30% discount.

If the Frontier X2’s price tag gives you pause, the original Frontier X is a worthy alternative. The difference in features between the two is not big. It boils down to 3x faster wireless data sync on X2, along with faster updates for heart rate on connected devices, 30 hours vs 24 hours data storage memory and improvements in battery life.

Essential reading: Top fitness trackers and health gadgets

The wireless, portable system uses lights and sensors with pre-programmed exercises to help you increase agility, reaction time and more. You essentially get a Flash Reflex Training system designed to supercharge your workouts.

I’ve been using it for the past few weeks. Here’s what I made of it.

BlazePod review: Design

BlazePod has its origins in a Kickstarter campaign that launched back in 2018. The project was successful having raised just over $160,000. The nearly 700 backers have received their product now and the gizmo has been made available to all on the manufacturer’s website.

In the box, BlazePod gets you get a total of six pods, straps, suction cups and plastic holders. There’s also a charging base and a nice little carrying bag.

Each unit is exactly the same. It’s circular with a diameter between 9 and 10 cm, and has a smash-proof exterior that is touch sensitive. The pods have very bright and powerful RGB LEDs on the top that can shine in one of 8 colours.

Everything looks and feels really quality made and very sturdy. Which is a good thing as you are meant to tap the pods in a variety of ways, including with your hands, feet, heavy wall balls, boxing gloves and more.

There are no on/off buttons and absolutely no moving parts. Instead you are meant to download the app and then connect via Bluetooth (BLE) with the pods. Just make sure the gear is no further than 40 meter away from your phone as that is the pod range. I found the Bluetooth connection works very well. The pods respond instantly and once connected stayed connected. Usually the link is instantaneous.

You don’t need to establish a connection with all of the pods. That’s not the idea. There are various exercises so you have the option of using as many as you like. The company says the maximum number of pods that you are able to simultaneously connect to depends on the mobile device itself. Most of the phones they tested could connect to 12 Pods. The theoretical maximum is 24 at a time.

All of this is very portable and lightweight as BlazePods stack neatly on top of each other. They don’t take up too much space particularly if you put them in the carrying bag that comes in the box. And that’s important because there are home workouts as well as those that can be done outside – the pods are water-resistant.

In fact, the company has used this design to come up with a unique way of charging. Stack the pods into a pile and place them on top of the charging unit. Make sure the charging pins are aligned when you do this. The lights on each individual pod will light-up in red or green depending whether the rechargeable li-ion battery is full or not.

On a single charge a pod is good for up to 12 hours of operation. So this is not something you will need to refuel very often. Nevertheless, BlazePod suggests you pop them on the charger about once a week to ensure optimal performance.

The pods come with some extra gear that includes straps and suction cups. These can be used, optionally, to add a bit more variety.

Attach the specialty plastic harness to the pods and that will allow you to add on the straps or suction cups. With that you can attach the pods to practically any surface. An idea might be to secure them to poles, fences, doors, mirrors, and pretty much anything else. Or as I preferred, simply use them without the straps and suction cups.

The design is UV protected so is safe to use in the sun and has a water-resistance rating of IP65. This basically means the BlazePods are splash-proof so can survive a rain shower, but don’t dunk them in the water.

All in all, everything looks and feels very smart, quality made. A bit Appelesque.

BlazePod review: Setup

Setting up the system for first use is not too difficult. Gather up the pods, stack them on top of each other and plug the charging unit into a USB port. Because this is the first time you are doing this, make sure to leave them on the charger for at least 2 hours. The pods start of by blinking in red but transition to green as they fuel up.

Once that’s done, download and open the iOs or Android app. Register your basic details and you’re all set to go. All of this went smoothly for me and I have not encountered any bugs.

There’s a section in the Blazepod app that has a list of available exercises. You can choose exercises right away although I found that it does take an hour or two to fully download all the accompanying images. After that you’re all set to go.

The concept is very simple yet extremely adaptable. It’s something called a Flash Reflex Training system that offers unique ways to work out. There are hundreds of exercises in the smartphone app to choose from.

To make selecting them easier, the exercises are grouped into several categories. For example you have Light Logic which offers the following choice: All at once, Focus, Home base, Random and Sequence. Some of these require you to use equipment, others do not.

There are other filters, too. You can sort exercises by Type (Agility, Anaerobic threshold, Balance Ball control, etc), Accessories (no accessories, balance board, basketball, basketball hoop, battle rope, boss ball, etc), by number of players and more. Once you find a few activities to your liking a good thing to do is to star them. That way they’ll be in your favourites list for quick access.

All of this allows for quite a variety in the types of workouts you can do. If all this sounds a bit complicated, don’t worry because it isn’t. Choosing an activity takes all of about a few seconds, and creating a new one from scratch just a few minutes. Yes, you can create one as well which means there’s an endless list of possibilities suitable for beginners or professional athletes.

Open up an activity and you’ll get more details that includes a description and picture showing how the pods should be arranged. This is also when you need to connect the required number of pods via Bluetooth to the app.

Click on the pods sign in the right-hand corner and select a pod. It will light up confirming that a connection has been established. Keep doing this until you have added the number of pods needed to do the activity. Then simply arrange them on the floor, wall, etc. – as indicated by the description.

The pods are designed to flawlessly integrate into exercises, pushing you to work on your reaction time and reflexes, as well as agility, speed, balance, and stamina. Users can run through different training modules and measure their performance down to the millisecond.

Custom activities

If you can’t find what you are looking for among the predefined activities, then the custom activities function is the place to go. It allows you to control the Pods’ capabilities to suit your own need, and build an activity according to your specific requirements.

You can design and save up to 10 different exercises using the multiple light logics (color options). I found this particularly handy during the COVID-19 lockdown as it allowed me to come up with several new ones that don’t take up much space and can be done in a small enclosed space.

Each custom activity has a set of controllable features that you’ll need to choose from. This includes defining the number of working stations and cycles, the number of pods to be used, the number of players, how to extinguish a light, light delay time and activity duration.

Combine these to your liking and save it. The possibilities are only limited by your imagination!

BlazePod review: How to use

Start up an activity by choosing either “now” or “on hit”. I preferred the second option as it gives you time to assume the necessary position. The exercise will start. When each pod lights up, it prompts you to move. The pods communicate with each other in real time and the smartphone app via Bluetooth.

Each activity is time limited but when you’re done you can choose to repeat the cycle. That way you can keep going until you’re worn out. Or switch to a different activity.

I’ve made a little video taking you through a few simple workouts. These require no other special equipment and can be done wherever there’s enough space.

Once you’re done the results will be saved in the app. They can be accessed by clicking the Analytics tab. This will show you a timeline displaying all the exercises that you have done so you can monitor progress.

Once again you get lots of filters. These allow for sorting by date, type of activity and player. Click on any activity and it will open up showing you how well you’ve done. You’ll get info on the number of hits and reaction time down to the millisecond!

My one gripe here is the lack of a leaderboard. While you can sort and filter activities there’s no ranking of your achievements. Which would have appealed to someone like me as I do enjoy to compete. I’m not sure how this could be done but perhaps implementing something like a points system that incorporates the number of hits and reaction might be an idea.

Having said that, I have found the concept really enjoyable. To me, one of the most appealing features of the product is that it has a modular design. It works with as many pods as you like, depending on which exercises you choose. You can train alone, with a friend or as a group – anywhere.

And it can tire you out pretty quickly. Plus because of the endless variety of activities, the boredom element does not set in.

BlazePod review: Bottom line

A great idea is an excellent starting point, but of equal importance is execution. And BlazePod does not disappoint on either count.

The concept is very simple yet extremely adaptable offering an infinite number of ways to exercise. Choose from the long list of activities or create one of your own. The modular design means you can use as many pods as you want.

What’s more you can utilise the various attachments to secure the pods to mirrors, doors and more. Or simply use them without any extra gear like I preferred to do.

BlazePod Gadgets & Wearables may get a commission

The pods are small in size so can easily be popped into a bag or rucksack. Plus they look great. The one thing on my wishlist are leaderboards in the app, as extra incentive.

I really enjoyed my time with BlazePod. The best part about the product is that it makes exercise fun!

There are different kits for different needs. The standard kit should suffice for most people. You can check all of them out on Blazepod’s website.
