The trademark application was submitted on October 16, 2026, under number 019436943. It is currently under examination by the European Union Intellectual Property Office.

The filing covers software for collecting and analysing biometric data, physiological signals and exercise parameters. It also includes exercise coaching, training instructions and applications related to fitness and wellbeing. Which is pretty broad.

What could Momentum Score actually measure?

Your guess is as good as ours at this stage. Momentum Score could be about keeping active day after day, tracking whether your fitness is improving, or simply showing how well you’re sticking to your exercise routine.

It might also have more to do with everyday movement than serious training. With Polar now selling the screenless Loop, a score that encourages people to move more, sit less and build better habits wouldn’t be a huge surprise.

Then again, perhaps Polar is thinking of something broader. Momentum Score could combine sleep, activity and recovery data to give you an idea of whether things are generally heading in the right direction. Or it might be a motivational feature that rewards consistency rather than pushing people to exercise harder.

There are quite a few directions Polar could take this. The problem is that the trademark gives us absolutely nothing about how the score would work or what it would actually measure. So, for now, we’re left guessing.

Another piece of Polar’s software plans

Polar has several other developments in the pipeline.

We previously discovered references to the Polar H12 inside the Polar Flow app. Subsequent app discoveries revealed additional connectivity details for the upcoming chest strap, including support for broadcasting heart rate to four Bluetooth devices simultaneously.

Polar also filed a European trademark for the H12 name on October 12, just four days before Momentum Score. That doesn’t mean the two are connected, and there’s currently no evidence suggesting the new metric would be exclusive to the sensor.

Adding another score would only make sense if it told users something they weren’t already getting from existing metrics. Whether Polar has found a useful new angle remains to be seen.

Oura announced on October 23 that it has filed a new complaint against Ultrahuman in the US District Court for the Eastern District of Texas. The company is seeking monetary damages and a permanent injunction that could stop Ultrahuman from selling the Ring Pro in the US.

The Ring Pro redesign did not end the patent fight

Ultrahuman’s new ring was built against a pretty awkward backdrop. Oura won an earlier case at the US International Trade Commission, leading to an import and sales ban on the Ring Air and forcing Ultrahuman to come up with a different design.

The Ring Pro was the answer. When Ultrahuman made it official in February, the company introduced redesigned internals, longer battery life and a new charging case, although the US was missing from the initial launch.

That redesign initially appeared to work. US Customs and Border Protection cleared the Ring Pro in March, allowing Ultrahuman to return to the market with a model that authorities considered outside the scope of the earlier exclusion order. We covered that development when the Ring Pro started moving towards its US return.

The important detail is that the Customs decision only addressed the patent involved in that earlier dispute. Oura’s latest complaint relies on two different patents, giving it another route to challenge the Ring Pro even after the redesign received clearance.

One is US design patent D804,471, which covers the ornamental design of a wearable computing device. The other is US patent 12,769,363, a newly issued utility patent describing a wearable ring with a curved battery, circuit board, charging magnets and optical, temperature and movement sensors. 

That second patent was issued on October 20, just two days before Oura filed its complaint. The timing makes it an unusually fresh addition to the dispute, although the issue of a patent does not by itself prove that Ultrahuman has infringed it.

Oura wants the Ring Pro off the US market

The complaint also names SVTronics, the Texas company that allegedly manufactures the Ring Pro at its facility in Plano. Oura claims Ultrahuman and SVTronics infringe its patents through the manufacture, importation and sale of the ring.

Ultrahuman is not backing away. CEO Mohit Kumar told TechCrunch that the company would defend its position and stressed that there is currently no court order affecting the Ring Pro. 

Oura has already shown that it is willing to use licensing agreements as well as court action. RingConn reached a multi-year deal with Oura that allowed it to continue selling its rings, while Ultrahuman has so far chosen to keep fighting.

For buyers, nothing changes today. The Ring Pro remains on sale, and there is no current court order preventing Ultrahuman from selling it. The longer-term picture is less settled.

Ultrahuman has sent us the following statement.

“We wanted to share some context directly regarding the patent complaint recently filed by Oura in the United States.

Ultrahuman remains confident in Ring PRO, the innovation behind it, and our continued growth in the smart ring category.

Ring PRO represents a substantially redesigned generation of our technology. Importantly, that redesign has already been through independent review in the United States: following an earlier patent proceeding, U.S. Customs and Border Protection determined that Ring PRO did not infringe the Oura patent considered in that proceeding.

Oura has now filed a new lawsuit asserting two different patents, one of which was issued on October 20, 2026, just two days before the lawsuit was filed. These newly asserted claims have not been adjudicated by a court.

The filing itself does not restrict the manufacture, distribution or sale of Ring PRO, and no injunction has been entered against Ring PRO as a result of this lawsuit. There is no change to our current retail plans or operations.

We respect legitimate intellectual property and are proud of the substantial investment Ultrahuman has made in its own engineering, science, product architecture and intellectual property. We will address Oura’s newly asserted claims through the appropriate legal process and will defend our position vigorously.

Competition and intellectual-property disputes are a natural part of building an important new technology category. They do not change our ambition or our pace.

For our partners, the message is simple: we remain focused on growing the category, supporting our retail network and continuing to bring differentiated Ultrahuman products and technology to customers around the world. Thank you for your continued partnership and confidence in Ultrahuman.”

The Galaxy Fit 4 looks very familiar

There really isn’t much visual detective work required here. The Galaxy Fit 4 keeps the same stretched rectangular display, rounded corners, single physical button on the side and conventional silicone strap that Samsung used on its predecessor.

The rear looks familiar as well, with the optical sensor sitting in the middle and the charging contacts alongside it. We already had a good idea Samsung was sticking with this design from our earlier Galaxy Fit 4 FCC investigation, but these renders give us a much better look at the finished device.

That earlier regulatory filing identified the tracker as model SM-R391 and repeatedly referred to it as “FIT4”. Samsung was already testing REV2.0 hardware back in July, so this isn’t something that appears to be sitting at the very early prototype stage.

The leaked renders don’t tell us whether Samsung has changed the display size, materials or overall dimensions. Visually, though, this looks much more like a tidy update to the Fit 3 than a redesign.

That’s not necessarily a bad thing. The Galaxy Fit 3 already has a large 1.6-inch AMOLED display and an aluminium body, so Samsung doesn’t have an obvious design problem that desperately needs fixing.

Most of the interesting stuff is still hidden

We actually know more about the Fit 4’s internals from regulatory documents than we do from today’s renders. Bluetooth 5.4 is confirmed, up from Bluetooth 5.3 on the Fit 3, and Samsung has already been testing production components including the battery and several charging bases.

What remains unclear is far more important for anyone deciding whether this is worth upgrading to. The battery capacity, detailed health sensor changes or whether the Fit 4 will finally get its own GPS all currently remain unknown.

For now, the biggest new information is simply that we can finally see the Galaxy Fit 4 properly. And unless Samsung has some much more interesting changes hidden inside, anyone expecting a dramatic visual upgrade from the Fit 3 probably isn’t going to get one.

The idea comes from a US patent application published on October 22, 2026, titled “Core Body Temperature”. It sounds a bit strange at first, but there is some clever thinking behind it. And no – it doesn’t involve wearing the charger all day.

Your charger plays a central role

Measuring temperature at your wrist is easy enough, many wearables do that. But figuring out what is happening deeper inside your body is much harder.

Skin temperature changes with the room, your clothing, sweat and all sorts of other things. So WHOOP is looking at how heat moves through the skin and the wearable, rather than relying on a skin temperature reading alone.

WHOOP’s patent describes a system using multiple temperature sensors. One would measure temperature near the skin, while another would sit inside the removable PowerPack. Additional sensors could measure temperatures at other points in the device.

During charging, the PowerPack would provide a controlled amount of heat. By measuring how temperatures change, WHOOP could build a better picture of the thermal properties of the wearable and the body underneath it.

That’s the real trick here. The charger isn’t somehow measuring the temperature inside your body directly; it’s helping WHOOP work out how to interpret the temperatures its sensors can actually measure. The system would then combine skin temperature, estimated heat flow and the calibrated thermal model to estimate core body temperature.

You wouldn’t need to keep the charger attached

Most people only put the PowerPack on when the battery needs topping up. And the filing does account for that. It specifically describes gathering useful temperature information during ordinary charging, without asking the wearer to do anything special.

The PowerPack could be used for calibration, with the resulting parameters stored to support later core-temperature estimates. In other words, charging could double as an opportunity for WHOOP to learn more about the heat passing through the device.

Our takeaway

WHOOP currently reports skin temperature, usually in the context of overnight trends and your personal baseline. A reliable core-temperature estimate could add another piece of information about the body’s daily temperature rhythm.

Other wearables are already experimenting with this. I recently tested the Speediance Strap Pro, which also estimates core body temperature, although it uses a different combination of heat-flow sensing, skin temperature and modelling.

The obvious use is exercise, particularly during longer sessions and training in hot conditions. Core temperature could give WHOOP another way to understand physiological strain beyond heart rate, HRV and the other signals it already uses.

There are possible uses outside exercise as well. Core temperature changes throughout the day and is linked with circadian rhythms, so it could potentially add another layer to sleep and recovery tracking.

Garmin has changed its mind

When CIRQA first arrived, Garmin was pretty clear about what it wanted the $199.99 tracker to be. You got health monitoring, activity tracking, recovery metrics and a vibration motor for alarms, but none of the usual smartwatch distractions.

In fact, when we covered Garmin’s explanation of CIRQA’s design choices, the company had confirmed that phone calls and notifications would not trigger vibrations. It wasn’t a hardware limitation, either, since the vibration motor was already there.

Now Garmin has reversed that decision. The official firmware 4.20 changelog specifically mentions support for vibration alerts from smart notifications and incoming calls.

There’s a slightly amusing detail here. Garmin’s own CIRQA support FAQ still says the band cannot vibrate for phone calls, text messages or other smartphone notifications. Clearly, someone hasn’t got around to updating that page.

Of course, CIRQA still doesn’t have a display. So you won’t be reading messages or checking who’s calling directly on your wrist. The band simply gives you a physical nudge when something arrives, leaving you to check your phone for the details.

A few workout improvements too

There’s more to version 4.20 than notifications. Garmin has added automatic Run/Walk detection for Trail Run activities.

Indoor workouts get some attention as well. Users can now calibrate recorded distance for treadmill running, indoor rowing and indoor cycling before saving an activity, while the Live Activity screen in Garmin Connect can show heart rate before recording begins.

Version 4.20 follows the substantial 3.20 update released in September, which introduced additional button controls and several Bluetooth-related changes.

The post Garmin CIRQA now vibrates for incoming calls and messages appeared first on Gadgets & Wearables.

That’s finally changing. The company has introduced a new Personal API, which means regular users can access their own data without going through the usual approval process. If you’ve ever wanted to build your own fitness dashboard, dig deeper into your training numbers or get AI to analyse your workouts, this could come in handy.

Your Garmin data, without the usual hoops

With Garmin’s new developer programme, you can now get your own API key straight from Garmin Connect. That means direct access to your workout files, health stats and other information your watch collects, without having to apply as a business developer.

So what could you actually do with it? Well, you could put together your own dashboard to see how sleep affects your training, look at heart rate trends over time or even use AI to make sense of your fitness history. There’s plenty of room to experiment.

The catch is that you’ll need to know your way around a bit of coding. Garmin isn’t adding any new tools to the Connect app itself. It’s simply making it easier for people to build their own.

We’ve previously covered ways to export and analyse Garmin data. This takes things a step further because you no longer have to rely on manual downloads or unofficial workarounds to get at your information.

But some workout metrics are still missing

Here’s the slightly odd part. Just as Garmin is making personal data easier to access, some third-party training platforms are receiving less information through their existing connections.

Runalyze, for example, recently reported that Garmin’s automatically delivered FIT files no longer include certain metrics. These include VO2 max estimates, recovery time, performance condition and some other Garmin-specific information.

The data hasn’t disappeared from Garmin Connect itself. Download the original FIT file manually and those metrics are still there. Garmin says it has been removing undocumented fields from files delivered to third parties, which explains the difference.

Runalyze has already introduced a workaround that lets users merge manually exported FIT files into existing activities. It works, but having to download and upload individual workouts isn’t particularly convenient.

There’s also the wider issue of how Garmin data moves between different services. We recently covered the shutdown of Intervals Pro, an AI coaching tool that closed amid uncertainty over restrictions on passing Garmin-sourced information between platforms.

The new Personal API doesn’t automatically resolve those commercial integration issues. Garmin has also reopened its business developer programme, with separate access options for smaller companies and larger platforms.

The practical implications for Garmin owners

For most Garmin owners, nothing really changes. Your watch will keep syncing as usual, and you won’t suddenly see a bunch of new features popping up in Garmin Connect. This is more about what you can do with your data outside the app.

And there’s plenty you could do with it. Garmin watches collect a huge amount of information, but Garmin Connect doesn’t always give you the best ways to explore it. Having more options is definitely a good thing.

The question is how much of that data Garmin will actually let people access. Opening things up is a step in the right direction, but the recent changes to FIT files suggest there are still some limits to what you can get your hands on.

For now, HONOR is accepting reservations for the Watch Fit 6 in China, but it hasn’t confirmed pricing or a date for wider availability. There’s also no indication yet that the full set of health features would be offered outside China.

A familiar design with a few practical touches

There’s a squarish case, raised edges, a rotating crown and an orange colour option with a sporty strap. HONOR also offers blue, green and two black finishes, so the overall look isn’t quite as dependent on Apple’s colour palette as the launch images might suggest.

Despite the chunky appearance, HONOR quotes a weight of just 31.8 grams for the watch body. The display measures 1.97 inches, uses AMOLED technology and has a 410 x 502 resolution, 60Hz refresh rate and advertised peak brightness of 3,000 nits. On paper, those are pretty decent specs.

HONOR says the watch has passed more than ten MIL-STD-810H durability tests. There’s also 5 ATM water resistance.

The 620mAh battery is another promising detail. HONOR describes battery life as long-lasting, but has not published a clear number of days for typical use, so there’s no point guessing how often you’ll need the charger.

Heart monitoring is the bigger story

The more unusual part of the Watch Fit 6 sits behind the case. HONOR says its optical sensor can support alerts for possible atrial fibrillation and premature heartbeats, with the pulse-wave alert software holding Class II medical device registration in China.

HONOR is also including sudden cardiac death risk screening. The system uses a measure known as heart rate deceleration capacity, or DC, which reflects aspects of how the autonomic nervous system regulates heart rate. It produces risk categories and reports, rather than detecting that a cardiac arrest is about to happen, so it’s worth keeping the claim in perspective.

This isn’t HONOR’s first attempt at this kind of monitoring. We covered similar cardiac risk screening on the HONOR Watch GS 5 earlier this year, while the more recent Watch 6 Pro goes further with an emergency response system for suspected cardiac arrest.

The rest of the health package includes overnight HRV trends, sleep apnoea risk screening, heart rate, blood oxygen and stress tracking. There’s also a daily energy estimate based on workout intensity, sleep and heart-rate information.

More than another long list of sports modes

HONOR has put some extra effort into gym tracking. The Watch Fit 6 can log exercises, reps and weights, and even show which muscles you’ve worked. That’s a step up from simply recording your heart rate during a gym session.

Runners get training plans and running-form analysis, while badminton and football have their own detailed tracking features. There are over 100 sports modes in total, so there’s plenty to play with.

You also get Bluetooth calling, NFC, downloadable apps and HONOR’s YOYO voice assistant with DeepSeek integration. Just bear in mind that these are features of the Chinese version, so international availability may differ.

How it would work

A US patent application published on October 15 shows how it could work. Instead of having to press your finger against a scanner, the ring would read your fingerprint as you put it on. So, in theory, something you’d be doing anyway could also double as a security check.

When you first set it up, the ring would take several scans and piece them together to get a complete picture of your fingerprint. After that, it wouldn’t need to do quite as much work. A single scan could be enough to check that it’s you wearing the ring.

Samsung has also thought about how to make this comfortable. The patent mentions tiny magnets and springs that would let the button move slightly as your finger passes over it. That way, the scanner can stay in contact with your skin without digging into your finger.

And because battery life is always a concern with something this small, the scanner wouldn’t need to stay switched on all the time. The button could wake it up when you put the ring on, so it’s only using power when needed.

There’s one other neat trick. The same button could tell when you’ve taken the ring off. Once your finger is no longer pressing against it, the button moves back into place, and the ring can let your phone or another connected device know it’s been removed.

A smart ring that could replace your fingerprint login

So what would you actually be able to do with a fingerprint-scanning ring? Samsung mentions a few possibilities, including unlocking your phone, logging into accounts and approving payments. Basically, the ring could become another way of proving that you are who you say you are.

For example, you could put the ring on in the morning, have it recognise your fingerprint and then use it to unlock your phone throughout the day. That would give smart rings a useful job beyond counting steps and tracking sleep.

There is one obvious catch, though. If the scanner only reads your fingerprint when you slide the ring on, would you have to take it off and put it back on every time you wanted to unlock something? That would get annoying pretty quickly, especially when your phone already has a fingerprint scanner.

Samsung may have a way around that. Because the ring can also tell when you’ve taken it off, it could potentially keep you authenticated for as long as you’re wearing it. Once you remove the ring, that trusted status could disappear.

Of course, getting all of this to work in a real product is another matter. There’s already very little room inside a smart ring, and Samsung would have to squeeze in the scanner and moving parts without making the ring uncomfortable.

As for whether we’ll actually see this in the Galaxy Ring 2, that’s anyone’s guess. Samsung hasn’t confirmed anything, and plenty of patented ideas never make it into products you can buy.

We do know that another Galaxy Ring is on the way. Earlier this year, Samsung’s head of digital health, Dr Hon Pak, confirmed that a successor is in development, although it may not arrive until 2027.

The Band 4 sits at the very bottom of Xiaomi’s fitness tracker range. It’s aimed at people who want the basics, without spending much money or worrying about charging their wearable every few days. There’s nothing particularly ambitious here, but at this price there doesn’t really need to be.

A familiar screen with a slightly nicer finish

At first glance, you’d be hard-pressed to tell the Redmi Band 4 apart from the Band 3. The screen is exactly the same, a 1.47-inch TFT LCD with a 172 x 320 resolution, 60Hz refresh rate and 450 nits of brightness. So nothing new to report there.

Xiaomi has made a few tweaks to the design, though. There’s now a metallic-looking frame around the edges and slightly curved 2.5D glass over the screen. The strap also has a new textured finish, along with an updated fastening that’s supposed to keep the band more securely on your wrist.

You can get it in black or silver. It’s also put on a tiny bit of weight, going from 16.5 grams to 18 grams without the strap. Not that you’re likely to notice an extra 1.5 grams on your wrist.

Battery life looks better on paper

Xiaomi says the Redmi Band 4 can keep going for up to 21 days on a single charge. That sounds pretty good, especially considering the Band 3 was rated for 18 days. But there’s a bit of a catch.

The 21-day figure is for lighter use, with some of the health tracking features dialled down. Keep those running regularly, including overnight, and Xiaomi says you can expect around eight days instead. That’s probably a more realistic number for most people.

And here’s where the comparison gets a little tricky. The Band 3 was rated for 18 days with typical use and nine days with heavier use. So Xiaomi isn’t really comparing like with like here. Both bands also have the same 300mAh battery, which means we shouldn’t assume the new model will last much longer in everyday use.

As for health tracking, there’s not much new to talk about. You still get continuous heart rate monitoring, blood oxygen measurements, stress and sleep tracking, plus women’s health features. There are also 50 sports modes, covering everything from running and cycling to table tennis. And with 5ATM water resistance, you can take it swimming.

The usual smartwatch extras are here too. You can check notifications, set alarms, look at the weather, control music and choose from more than 100 watch faces. In China, there’s also support for QR-code payments through WeChat and Alipay.

One thing we haven’t seen confirmed is NFC. QR-code payments don’t need it, so don’t take the presence of WeChat and Alipay as a sign that you’ll be able to tap your wrist to pay at a checkout. For now, that’s still an open question.

When can you get it?

Redmi Band 4 has just gone on sale in China for 169 yuan, which is roughly $25. That’s a small increase over the 159 yuan launch price of Band 3.

No international release date for now. Xiaomi has brought earlier Redmi bands outside China, including the Redmi Smart Band 2, so a wider release is expected.

Looking back at the original Redmi Band from 2020, which launched for just $14, the range has certainly come a long way. We actually reviewed the Redmi Smart Band Pro back in 2021 and came away reasonably impressed with what Xiaomi was offering for the money. It wasn’t perfect, particularly when it came to syncing, but it was a solid budget fitness tracker at the time.

For someone buying their first fitness tracker, Redmi Band 4 looks like a reasonable option at this price. Existing Band 3 owners, on the other hand, probably won’t find enough here to justify upgrading.

The Apple Watch Companion project popped up on GitHub on October 9, and it goes much further than just piping a few Android notifications to the watch. The software recreates enough of Apple’s own pairing system to find the watch, pair it, activate it, reconnect later and control parts of it from Android.

The missing iPhone is the important part

Apple’s official setup instructions still begin by telling users to pair their Apple Watch with an iPhone. Even Apple Watch models with cellular connectivity need an iPhone during the initial setup, so Android users cannot normally take a new or reset watch out of the box and activate it.

We have already seen phone makers chip away at that restriction. Xiaomi now lets an Apple Watch work with its Android phones, bringing calls, messages, notifications and some health data into HyperOS 4. The rather large catch is that an iPhone is still needed to set up and activate the watch before Xiaomi takes over.

The Apple Watch Companion goes further because it attempts to handle the original pairing and activation process itself. In the developer’s test, the Apple Watch was set up directly from Android without an iPhone acting as the middleman.

This is nowhere near a normal Android app

Before anyone gets too excited, the current setup is about as far from plug and play as it gets. The Android version requires a rooted phone and a Magisk module that interacts with the phone’s Bluetooth hardware. If the phrase “Magisk module” means nothing to you, this is not something you should be installing yet.

The project documentation says the Android hardware layer currently accepts only the OnePlus CPH2653, better known as the OnePlus 13. Testing has been carried out with an Apple Watch Ultra 2 running watchOS 26.2 build 23S303. That is a very specific combination.

A code update published on October 13 removed some of the hard-coded Apple Watch Ultra 2 restrictions. That should make it easier to add other models, but it does not mean those watches have suddenly been tested or confirmed to work. T

Some of the basics already work. You can see watch information, change a few settings and mess around with native watch faces. Getting an Apple Watch paired, activated and reconnecting securely to Android is the clever bit, but that does not suddenly turn it into a fully working Android smartwatch.

There are still plenty of gaps. Health and activity syncing is unfinished, calls and audio are not properly working yet, and notifications are still a work in progress. So yes, you can get past the Apple pairing setup without an iPhone, but you are still a long way from replacing Apple’s Watch app.

It is still worth noting

People have been trying to get Apple Watch working properly with Android for years, but it has always been far too messy for normal use. This project is not ready for everyday users either, but it does show that an Android phone can pair and activate the watch without an iPhone.

Making it genuinely useful will be much harder. Notifications, calls, health syncing and software updates all need to work reliably, while support would also have to expand to many more phones and Apple Watch models.

So no, this is not a reason to buy an Apple Watch for your Android phone just yet. It is still an early project for people who are happy rooting phones and dealing with unfinished software, but proving that an iPhone is not essential during pairing makes it worth watching.
