You know the feeling. You’ve woken up feeling strangely worse after what should have been a full night’s sleep. Well, something like this can help. The company is positioning it as the final piece of its “Sleep, by Design” platform. It sits alongside Sleep Assist for falling asleep and Deep Sleep Boost for supporting slow-wave sleep.

A smarter way to wake up

The idea here is simple. But the technology behind it is more interesting than the typical smartwatch-style smart alarm. Rather than estimating sleep stages from movement or heart rate, Muse is using EEG data directly from the headband.

That matters because the whole point of a smart alarm is timing. If you are being woken at the wrong point in your sleep cycle the grogginess can linger well into the morning. Muse says Smart Wakeup continuously monitors brain activity during your chosen wake window and starts a gradual audio alarm the moment it detects lighter sleep. If that moment does not arrive, it still wakes you at the latest set time.

That direct EEG approach is one of the things that stood out to me in my hands-on review of the Muse S Athena. The device’s brain visualisation tools and signal quality were already among its strongest points. So this feels like a natural extension of what the hardware is already good at.

The data behind it

Muse says the feature was developed using an internal study based on around 6,200 nights of sleep data. Some 1300 users in total were looked at, with each session paired to morning mood ratings.

The most interesting takeaway is that sleep duration still matters far more than anything else. In other words, this is not being presented as a fix for poor sleep habits. But for nights where users already got seven or more hours with good sleep efficiency, waking during lighter sleep was linked with noticeably better morning mood.

That feels believable. Anyone who tracks sleep regularly will know that seven hours can feel very different depending on when the alarm hits. Some mornings you wake naturally a few minutes before it goes off and feel clear-headed. Other mornings the same alarm time feels brutal.

Muse’s point is that the timing of your sleep stages shifts from night to night. Travel, stress, schedule changes and even minor routine differences can move REM and lighter sleep periods around, which means a fixed 7am alarm does not always hit the same sleep stage.

What comes next

The company is already talking about where this platform goes next in 2026, and this is where it gets especially interesting. Planned additions include waking once a recovery target has been met, a mode designed to wake users during REM for dream recall, and guided audio layered into the transition from sleep to wakefulness.

Some of that does stray into more speculative territory, but Smart Wakeup itself feels grounded and genuinely useful. Based on my experience with the Muse S Athena, this is exactly the kind of feature that makes sense for the platform. It builds on the headset’s clinical-style EEG strengths rather than trying to imitate what smartwatches are already doing.

What makes Smartbuds different

Most sleep wearables just sit back and watch. Smartbuds actually do something. They’ve got six dry-contact EEG sensors that track your brainwaves in real time, then play gentle sounds to help keep you in deep sleep. It’s all done with a feedback loop that kicks in when your brain starts drifting out of that restorative zone.

Inside, you’ve got two high-res EEG channels sampling at 1000 Hz. That’s the kind of quality you’d normally see in lab gear. The sensors are placed around the ear canal and outer ear, using a special Tecticoat layer to keep readings stable without any messy gels.

Instead of guessing sleep stages based on movement or heart rate, Smartbuds go straight to the source. You get brainwave data, not ballpark estimates.

Comfort and audio matter too

The earbuds weigh around 5 grams each and come with three sizes of tips and wings. Conductive silicone ensures both comfort and signal fidelity. Battery life hits nine hours on a single charge, and the case holds four extra charges via USB-C.

You can stream your own music, podcasts or use NextSense’s own soundscapes. Audio quality uses 6mm drivers with a standard 20Hz to 20kHz frequency response, and users in the beta rated them highly. The company says – among those with prior earbud experience, 69 percent said the sound quality was better than what they were used to.

They’re not just for sleep either. Since the EEG sensors can pick up alertness and neural patterns during the day, there’s future potential for cognitive tracking during waking hours. The tech is already being explored with academic partners.

Backed by research and tested in real-world use

NextSense ran a controlled test over 106 nights and found Smartbuds increased slow-wave activity. Around half the participants said their sleep was better or much better, and the improvements extended into morning recovery scores.

The company says it has gathered over 1,000 nights of in-ear EEG data so far, making this one of the largest consumer-facing datasets of its kind. Clinical collaborations are ongoing, with published results expected later in the year.

Jonathan Berent, founder and CEO, says the whole idea stemmed from a moment of frustration with heart health tech. After getting an atrial fibrillation alert from a smartwatch, he realised there was still no simple way to get meaningful brain data at home. That gap led to his decision to leave Alphabet’s X division and create NextSense.

Pricing, app support and availability

Smartbuds cost $249 during the early launch window, with full retail set at $399. They come with three months of the Fit Kit subscription, which sends fresh ear tips and wings each month to preserve EEG signal quality. After that, it renews at $14.99 per month but can be paused or cancelled at any time.

The earbuds currently work only with iPhones running iOS 17 or later. There’s no mention yet of Android support. Syncing is event-driven and continuous, using Bluetooth 5.3 with LE Audio and standard streaming protocols.

Deep Sleep Boost works with your brain

This isn’t about calming bedtime stories or generic white noise. Deep Sleep Boost detects slow-wave sleep with EEG in real time and delivers pink-noise pulses that are phase-timed to the user’s actual brain oscillations. These pulses are designed to gently reinforce slow-wave activity, the part of sleep most tightly linked to physical recovery, memory consolidation and long-term brain health.

In my review of the Athena headband I found it feels familiar to earlier Muse models but packs noticeably more detail under the hood, with upgraded EEG sensors and the addition of fNIRS for tracking both brain activity and how hard your brain is working during sessions. The sleep tracking was accurate and detailed, with clear visualisations of brainwaves and solid overall performance night after night.

What’s new here is not just sound during sleep, but smart, adaptive stimulation based on the exact timing of brainwaves. That level of precision is what Muse believes sets it apart from traditional sound-based sleep tools.

The science behind it isn’t new, but now it’s usable

Closed-loop audio stimulation has been around in research for years. Trials have shown that when delivered correctly, these cues can boost slow-wave activity by as much as 50 percent and improve memory retention overnight by around 20 percent. One Alzheimer’s study saw a 60 percent increase in time spent in deep sleep using similar stimulation protocols.

Muse has essentially translated this into a real-world feature for nightly use. According to the company, their AI models were trained on large-scale EEG datasets and refined using years of longitudinal brain data from Muse users. The goal was to bring clinical insight into a consumer setting, without the clunky lab gear.

The system is also modular. Muse users can combine Deep Sleep Boost with other features like Sleep Assist, which plays EEG-guided sounds to help users fall asleep faster, or pair it with Sleep Sounds like “Ocean Stillness.” Everything runs inside the same mobile app, with an option to preview results the next day.

It’s designed to help with depth, not just duration

Many people sleep long enough but still wake up groggy. Muse is aiming at the quality side of the equation. Deep sleep tends to decline with age, stress, or irregular routines, and boosting it without drugs or wearables that just guess at your sleep stage is a tough problem. That’s where Muse’s EEG tracking and adaptive timing come in.

The feature only kicks in once you’ve actually reached deep sleep. A visual in the app shows a confirmation: “Will be active when you reach deep sleep.” It also tracks how many times it triggered during the night and displays that next to your sleep staging and slow-wave intensity score the following morning.

The system supports customization too. Protocol 7 is the current preset, but the app offers advanced settings for intensity and timing. Muse recommends using wired headphones for the most accurate audio timing, though the experience still works wirelessly.

Included for free with Athena

Deep Sleep Boost is already live and free for anyone using a Muse S Athena, whether you’re on Android or iPhone. It’s part of Muse’s bigger Sleep by Design toolkit, which also includes features like the upcoming Smart Alarm and the Enso AI coach. The idea is to go beyond just tracking sleep and actually help improve it using real brain data.

The whole thing is designed to live next to your bed and do just one job well.

Built for tired hands and sleepy eyes

Dreamie is a low, rounded device about the size of a small lamp base. It features an ambient screen, along with a top-mounted control knob that doubles as a directional light joystick. This physical interface is central to the experience. You can point the light softly at a wall or angle it down onto a book without needing to cycle through settings. Tactile volume sliders and a dimming touch strip complete the controls.

Essential reading: Best fitness trackers and health gadgets

There’s no app to download or account to make. Dreamie is fully self-contained. That’s intentional. It’s designed for users who want sleep tools without a screen pulling them back into notifications or swipes.

It’s earned a Platinum Calm Tech certification, which reflects how little it demands from you. If you’re half-awake, groggy or just not in the mood to fiddle with menus, Dreamie’s layout makes it easy to use anyway.

A sunrise alarm that doesn’t blast you awake

Dreamie includes a 120-LED lighting array tuned to 2700 K by default. It supports full spectrum colour output but emphasises warm tones and flicker-free operation. You can dim it all the way down or let it fade out completely. When used as a sunrise alarm, the light ramps up gradually, alongside sound, to ease you into the day.

This isn’t a decorative light show. It’s a tool for sleep rhythm support. You can set different wake times for weekdays, weekends or ad hoc events without needing to reprogram anything in an app. One swipe starts a whole routine.

It remembers your preferred volume for masking sounds at night and uses a separate level for morning alarms. That split alone helps avoid the common issue of falling asleep to a thunderstorm track and waking up to a blast.

You will also find a built-in library of noise types like brown, pink and green noise. Along with environmental soundscapes, guided sleep tracks and a podcast player. All of it is updated over Wi-Fi, with no need for a phone or login. Bluetooth pairing is available if you want to listen privately through headphones.

To round everything off, the gadget tracks sleep through contactless sensors embedded in the body. These monitor movement, temperature, humidity and light. Morning summaries are available on-device and focus on environmental factors and basic rest patterns.

Price and where it fits

The device stores all data locally and encrypts it on the device. There’s no cloud sync, and nothing leaves your bedroom. You never even enter a name or email. If you want the device to be purely a lamp and sound player, that’s entirely possible.

The Dreamie currently retails at $279 during a holiday window, with a standard MSRP of $349.

If you want to wake up without a jolt, fall asleep without a phone in reach, and keep your data where it belongs, this circular bedside assistant makes a compelling case. It’s not trying to track every metric. It’s trying to give sleep its own dedicated space. And that’s something most bedrooms don’t really have anymore.

Why this lamp doesn’t need to touch you

Unlike smartwatches or rings, Sleepal’s system doesn’t rely on physical contact. You can leave your wearable charging or skip it entirely. The lamp sits by your bed and picks up on your body’s subtle signals throughout the night. That includes heart rate, respiratory rate, body movement and sleep stage transitions. It also tracks snoring, which can be useful for identifying interruptions in breathing or disturbances you may not be aware of.

The tech powering it uses millimeter-wave radar or ultra-wideband sensors to detect micromovements, even under heavy blankets. This approach avoids common accuracy issues in app-based microphone solutions that rely on where the phone is placed, or how much battery it has left.

Privacy is a key part of the pitch. According to the website, data processing happens locally, not in the cloud. That makes it less vulnerable to leaks and avoids sending raw biometric data over the internet.

The AI engine and app experience

Sleepal isn’t just tracking your breathing and movement. Behind the scenes, it’s running your data through a bunch of AI models that were trained on thousands of proper sleep studies. That gives it a decent shot at figuring out whether you’re in REM, deep or light sleep without needing anything strapped to your body.

The app then pulls all of that into a simple sleep score and breaks down your night in graphs and trends. There’s also an assistant built in that nudges you with suggestions, like dimming the lights earlier or shifting your bedtime based on how things have been going.

Beyond tracking, it functions as a lamp

The really nifty things about this is that it doubles as a room light with circadian-friendly controls. Expect sunrise simulations in the morning and warm lighting in the evening. There’s also a full-colour touchscreen dial with smooth dimming for manual control. Early images show a modern, cylindrical form that fits neatly on a nightstand.

Internally, it packs a surprising number of sensors. Acoustic analysis detects snoring and ambient noise. Thermal sensors help with body pose awareness. Radar-based modules pick up heart rhythm, breathing patterns and even presence sensing. It also monitors the room itself. This includes keeping tabs on temperature, humidity and light exposure to better understand how your environment affects sleep quality.

Designed to simplify the routine

This sounds a bit like some products we have reviewed in the last few years. One of these is SleepScore S+. Like Sleepal Ai Lamp, it uses radio waves to pick up on your breathing and body movement from a distance. It works a bit like echolocation, sensing what’s happening without touching you or the bed.

One of the biggest appeals to this kind of tech is convenience. The Sleepal lamp begins monitoring the moment you lie down, with nothing to wear, charge or sync. For people sensitive to wristbands or rings, it’s a way to get detailedsleep insights without a smartwatch or any other fitness gear.

The product is still in its pre-launch phase, with a Kickstarter campaign planned. You can sign up on the official site to reserve a launch discount. For those in Las Vegas, the device will be demoed at CES 2026 – where it has picked up a Honoree award in the Accessibility & Longevity, Smart Home and Digital Health categories.

The post CES 2026: Sleepal AI Lamp rethinks sleep tracking from the nightstand appeared first on Gadgets & Wearables.

Apple Watch sleep tracking has a data problem

The Apple Watch already tracks sleep, but its staging data is limited. It uses heart rate and wrist motion to divide sleep into light, deep, and REM stages. The data gets synced to the iPhone’s Health app, where users can view overnight breakdowns. While useful for spotting sleep trends or encouraging better habits, the accuracy isn’t strong enough to be used in clinical settings or in formal research.

Studies show the Apple Watch does well at detecting whether you’re asleep or awake. But when it comes to identifying specific stages like deep or REM sleep, it becomes less reliable. For example, in one peer-reviewed analysis, the Apple Watch had high accuracy for light sleep but only around 50 to 60 percent accuracy for deep sleep. That might explain why some users report waking up after eight hours of sleep only to see their watch claim they had just a few minutes of deep sleep.

Part of the issue is that wearables like the Apple Watch are making guesses based on proxies, not direct brainwave activity like EEG. So while it can spot when you’re still and your heart rate slows, it has a harder time distinguishing which phase of sleep you’re actually in.

What BIDSleep adds to the mix

This is where BIDSleep becomes interesting. Developed by Professor Joyita Dutta’s team at UMass Amherst, the app runs on the Apple Watch and collects high-resolution heart rate data during sleep. That data is processed by an AI model trained to classify sleep stages. The model reached 71 percent accuracy in benchmark testing, which is higher than many wrist-based methods and closer to the gold standard used in sleep labs.

Essential reading: Top fitness trackers and health gadgets

The standout claim is that BIDSleep does a better job identifying deep sleep. That matters because deep sleep is when the brain consolidates memory, clears waste, and resets itself for the next day. It’s also one of the hardest stages for consumer wearables to get right. So improving this one metric could have outsized benefits for understanding long-term health.

Why this matters for research and users

Sleep labs typically involve a single night of testing with full EEG setups, which doesn’t always reflect a person’s regular sleep. By using a standard Apple Watch paired with a smart algorithm, researchers can collect data over many nights, in real-world conditions, without asking people to sleep with wires on their heads. That shift in how data is gathered could help uncover long-term patterns linked to neurodegenerative disease, mental health, or cardiovascular risk.

It also levels the playing field. Most universities and clinics don’t have access to large-scale sleep labs. But they do have access to students or patients already wearing Apple Watches. With BIDSleep, the watch becomes more than a lifestyle tool. It becomes a gateway for science.

This approach also raises interesting questions. If consumer hardware paired with better software can meet research standards, do we still need dedicated sleep devices for all studies? Could regulatory bodies one day accept this type of data for medical screening or diagnosis? And what role will Apple play, given that most of this is happening outside its own sleep tracking framework?

The Apple Watch still isn’t a lab-grade sleep tool on its own. But paired with research-driven apps like BIDSleep, it edges much closer. It shows that the limitations of wearable sleep tracking may have more to do with software than hardware. And for researchers, it opens up a low-cost way to study sleep at scale, over time, in real conditions.

The post UMass app aims to make Apple Watch sleep data clinical-grade appeared first on Gadgets & Wearables.

What this means is that – you don’t need to wear an Apple Watch to get Apple’s version of how well you slept.

Works with Garmin, Amazfit and more

People running the watchOS 26 beta have started seeing the new Sleep Score in the Health app. The Release Candidate landed yesterday, and the full version is expected to roll out on September 15. Once that happens, it should be available to everyone.

This includes people who track sleep using third-party devices. As long as your wearable pushes sleep stages and duration into Apple Health, the score appears. It doesn’t matter if you have an Apple Watch, Garmin, Withings or another brand’s wearable.

Essential reading: Top fitness trackers and health gadgets

There’s nothing to turn on. No pairing tricks. Just make sure your device of choice is syncing sleep properly. If you’ve been doing that for a while, Apple’s already applying the new score to your past sleep too. You might open the Health app and see it’s gone back and filled in last week’s data.

Apple has its own take on sleep quality

Apple has introduced Sleep Score as a new metric for its watch. If your sleep data comes from Garmin, Withings or Amazfit instead of an Apple’ Watch’s device, you might notice some differences. Apple analyses the raw data it receives and calculates its own score. Its algorithm handles the entire process.

The app looks at how long you slept, how often you woke up, how regular your bedtime is and then gives you a rating. You’ll see one of five categories: Excellent, High, OK, Low or Very Low. It’s Apple’s version of how restorative your sleep was.

This might not match what your Garmin or Amazfit watch says. That’s expected. Every brand has its own way of judging sleep. What you’re getting here is Apple’s opinion based on your shared data. It’s simple, clear and easy to check in the morning.

Here is an example a Redditor posted. It compares sleep score generated by the Amazfit Helio Band and Apple Health. Same data, two different scores.

This changes things a bit

It’s rare for Apple to roll out a health feature that works this smoothly with third-party hardware. You can now wear a Garmin or Amazfit to bed and still get a native Apple Health sleep score in the morning, no Apple Watch needed. That’s useful.

If this is the direction the company is heading, Health might slowly become more open. Less tied to Apple Watch. And that’s a win for people who prefer other wearables but still want to keep their data in one place.

The post You’ll get Apple’s Sleep Score even with a Garmin or Amazfit appeared first on Gadgets & Wearables.

The launch doesn’t bring surprises. The device had already leaked in full a week ago, and everything from the design to the feature list was known in advance.

A sleep band with familiar data

Let’s make it clear from the outset – if you were hoping this would add new insights to Garmin’s health tracking ecosystem, it does not. The Index Sleep Monitor captures the same metrics Garmin watches already provide at night including sleep stages, sleep score, HRV status, breathing rate, skin temperature, resting heart rate and Pulse Ox. It also includes the usual integration into the Garmin Connect app, syncing alongside daytime data from your watch to build a full 24-hour profile.

But unlike a watch, the Index Sleep Monitor is worn on the upper arm. That is the pitch. A more comfortable option for overnight wear, especially for those who dislike sleeping with a device strapped to their wrist.

A comfort play rather than a data upgrade

So the core benefit here is not what it tracks, but where and how. The band is lightweight, breathable and machine washable. Garmin makes a point of emphasizing comfort throughout its marketing. It also throws in a smart wake alarm that vibrates on your arm instead of buzzing on your wrist, which may appeal to lighter sleepers.

Essential reading: Top fitness trackers and health gadgets

The bigger question is whether the sensor position will result in better quality sleep data. Garmin does not claim any such advantage. But for those who find wrist-based readings inconsistent or uncomfortable, this could be worth exploring. It might also appeal to users who want sleep tracking but do not want to invest in a full smartwatch.

What Garmin left out

At 170 dollars, the Index Sleep Monitor sits in a strange place. It is more expensive than many entry-level wearables that track both day and night. And unlike Whoop, it only covers sleep. That limits its appeal, especially for users looking for continuous recovery metrics or athletic insights.

There is also a hardware angle Garmin completely missed. The band fits on the upper arm, which would have made it ideal as something that could double up as a heart rate monitor for workouts. Something like the Polar Verity Sense, for example. Garmin currently does not offer anything like that, relying entirely on chest straps for serious heart rate tracking. A dual-purpose sleep and workout band could have made this a much more versatile product.

Instead, what we have is a sleep-only companion for people who want recovery data but do not like sleeping with a watch. If that sounds like you, this could be worth a look. Check it out on Garmin’s website.

The post Garmin Index Sleep Monitor is official, but feels like a missed opportunity appeared first on Gadgets & Wearables.

Hardware keeps things simple

Reportedly, the unit is made to wrap around the upper arm with a Velcro strap, while the optical sensor tucks into a small pocket within the band. It looks to be the familiar Elevate setup from their watches, just removed from a traditional casing.

There are no metallic parts on the underside, so ECG is off the table. The whole thing is screenless. Just a single LED sits near the sensor to give you a sense of battery life. You won’t find physical controls either. Charging is done via Garmin’s usual proprietary cable, and the battery should last about a week if you’re logging a full night’s sleep each night.

That’s about it, at least in terms of what we know from the leak.

From a usability standpoint, this is clearly not something Garmin expects you to fiddle with. It seems almost entirely passive. If you want to use it as an alarm, you’ll feel a vibration instead of hearing a sound. You can tap the band to snooze or stop it, but that’s the extent of interaction mentioned so far.

It tracks a lot but… doesn’t your watch already?

Garmin watches already give you things like Sleep Score, Sleep Stages, SpO₂, Respiration Rate, and even Body Battery. So if this device is just doing the same stuff, why release it? That’s where things get fuzzy.

It’s possible this band pulls more accurate data from the upper arm compared to the wrist, especially during deep sleep. Or maybe it’s just a comfort option for people who don’t like wearing watches in bed.

Essential reading: Top fitness trackers and health gadgets

Right now, it slots into Garmin’s Index range alongside the Index S2 smart scale and Index BPM blood pressure monitor. So it could also be about building out a more medical-style ecosystem, rather than just offering another tracking option.

This feels incomplete

If this really is just a passive sleep band with nothing new under the hood, then I’m not sure who it’s for. But I doubt that’s the whole story. Garmin usually doesn’t release single-purpose devices without a bit of extra thought. My guess is that there’s more going on with metrics or recovery analysis that hasn’t surfaced yet.

The obvious comparison is with Whoop, but even that feels slightly off. Whoop is a 24/7 system, while this seems like a nighttime-only companion. If it’s truly limited to sleep, then the only people I see picking it up are those who want to leave their main watch off at night. Which is fine, but niche.

The estimated price of €170 isn’t outrageous, but also not low enough to make it an impulse buy.

The post Garmin Index Sleep Monitor might be real but seems oddly limited appeared first on Gadgets & Wearables.

The team over at 9to5Google got their hands on the latest Fitbit app file Google tossed onto the Play Store. When they cracked it open, they found bits of code suggesting features that might see the light of day at some stage. The plan seems to be about giving you a sleep setup tailored just for you.

How it’s supposed to work

Here’s the gist of it.

You’d share a few tidbits about your day—like how wiped out or peppy you feel at different points—and Fitbit Labs would crunch that alongside your sleep and activity data. From there, it’d spit out a bedtime and wake-up time that’s meant to fit you like a glove. It’s really just a way to figure out what your body’s asking for sleep-wise. You’d get little check-ins—morning, midday, evening—where you’d say how you’re holding up.

Once they’ve got your input, the app would let you know how much sleep you actually need and even tally up any “sleep debt” you’ve racked up in the previous few days. They’d break it down for you, too, so you’re not just staring at numbers wondering what went wrong.

Whoop has had a version of this for years. More recently, Garmin came on-board with its own sleep need suggestions. As someone who wears both of these devices on a daily bases, I can vouch about their usefulness. Most people don’t get enough sleep as it is, so anything that nudges them in the right direction is useful.

Tweaking your routine

If this all pans out, Fitbit wouldn’t just leave you with a suggestion and call it a day. After settling on your ideal sleep times, it’d prompt you to tweak your alarms to match. It’s all a gentle push to get your routine in line with what the data’s saying. They do suggest sticking with it for at least five days—wearing your Fitbit, of course—to let the numbers settle into something reliable.

Essential reading: Top fitness trackers and health gadgets

For now, this is all still in the “coming soon” phase. The strings of code are there in version 4.37, but you won’t see it live in the app just yet. If you’re curious, you can poke around in the Fitbit Labs section—top-right corner, under the account menu—to see if it’s popped up. For those not in the know, Fitbit Labs is a testing ground where Fitbit rolls out experimental features for users to try out before they go mainstream.
