Fresh FCC documents bring new hardware clues

An interesting detail in the FCC filing, submitted under FCC ID 2AD7V-OURA2602 and published April 8, 2026, is the appearance of two distinct model references, with the ring listed as OA13 and the charger as OA14. The documents also mention a commercial sample ring in size 13, which is a useful clue because language like that usually points to production-like hardware rather than an early engineering prototype.

The filing further references a dedicated square charging dock, broadly similar in form to the current Oura Ring 4 accessory. While the overall design and wireless charging technology appear familiar, the separate model identifiers suggest Oura is certifying updated hardware rather than simply refreshing paperwork for an existing product.

The timeline now looks much closer

The earlier leak suggested a late 2027 launch window for the Gen 5 device, which felt like a reasonable read then. The FCC documents now include a marked 180-day confidentiality request, which pushes the outer deadline for currently hidden materials such as internal photos and the user manual to early September 2026.

That does not automatically mean a launch in September. In practice, companies often release products before the confidentiality period expires, using that date more as a backstop.

All this means the earlier 2027 timeline now looks less likely. A launch in late summer or early autumn 2026 feels like the stronger reading based on the paperwork.

Could this still be a different ring?

Of course, there’s an important caveat.

It is worth keeping in mind because the naming remains unconfirmed. While it is tempting to connect this directly to the earlier Oura Ring 5 leak, the FCC documents don’t specify the name of the device.

All we can say with confidence is that Oura has a new smart ring in late-stage certification. Which leaves open two realistic possibilities. The first is that this may indeed be the device shown in the earlier leaked images and widely referred to as Oura Ring 5. But it could also be another future model, a revised version or a regional variant that has not yet been publicly identified.

Our takeaway

Regardless, the new FCC filing adds more substance to the earlier Oura Ring 5 leak and moves it beyond pure speculation territory. It gives the original report something much more solid to build on, namely new hardware identifiers, a refreshed charger design and a launch window that now looks far closer than the previously suggested 2027 timeline.

At the same time, the paperwork does not confirm the final product name, so it is still not possible to say with certainty that this is the device shown in the earlier leaked images. What the filing does make clear is that Oura has new ring hardware in late-stage certification.

A replaceable battery design

The newly granted US patent describes a wearable ring made up of two main sections. The inner portion houses the sensor system and core electronics, while the outer curved portion includes the battery housing. Crucially, the filing states that the battery is removable and may be configured so that a user can remove and reinsert it without compromising the functionality of the device. 

The patent also goes into more detail on how this could work in practice. It describes electrical contacts between the removable battery section and the main ring body, suggesting Oura is also protecting the way power would be transferred once the battery module is slotted back in. 

Oura also appears to be covering different ways the battery section could be secured in place. The filing references retention elements, sockets and coupling structures, which suggests the company is exploring more than one hardware approach for attaching and removing the battery module. 

The outer section itself is described as being made up of first and second sub-portions. In practice, this appears to be a two-piece curved shell that fits around the main ring body, forming the removable battery housing. 

Why this is useful

This could be a useful development for the smart ring category because battery ageing is one of the main factors that limits the lifespan of small wearables. Some Oura users have reported battery life dropping noticeably after a year or two, with devices that once lasted several days needing daily charging.

A removable battery design could offer a more practical long-term solution. Instead of replacing the entire ring when battery performance starts to decline, users may only need a new power module, which could also make repairs and warranty replacements simpler. For a premium device designed for continuous wear, that would be a useful change.

Of course, as always with patents, there is no guarantee this will appear in a commercial product. But this one is actually not a bad idea. It stands out because it tackles a very real issue for compact wearables: long-term battery life.

The screenshots suggest this is more than a simple headache log. Ultrahuman appears to be building out a fairly detailed migraine support layer inside the app

A new PowerPlug focused on prevention

From what is visible in the screenshots, Migraine Insights is built around the idea that the body shows subtle changes before an episode starts. The app explicitly mentions using the Ring’s biomarker data to surface these early signals.

That includes trends in heart rate variability, sleep patterns and recovery. Users are shown how these metrics relate to their headache history, with the app encouraging them to identify shifts that may precede discomfort. There is also mention of menstrual cycle phase tracking, which suggests Ultrahuman is trying to account for cycle-related migraine patterns as well.

This feels like a logical use case for a smart ring. Continuous overnight biometrics are one of the device’s strongest suits, and migraine sufferers often report that poor sleep, elevated stress and dehydration can all act as triggers. To remind, RingConn has recently brought out a similar feature – and it works fairly well.

More than symptom logging

A lot of headache apps stop at journaling symptoms after the fact. This one seems to go quite a bit further.

The screenshots show a full headache diary where users can log severity, duration, symptoms, pain location and medication use. There is also hydration tracking, personalised daily goals and smart habits such as sleep duration and water intake targets.

That last part is probably where this feature may prove most useful. Rather than simply recording that a migraine happened, the app seems to be nudging users toward habit changes that may reduce frequency over time.

The inclusion of an eight-week structured learning program is also notable. Lessons cover stress management, cognitive techniques, mindfulness and practical daily skills, with new content unlocking each day. Ultrahuman says the program is powered by Click Therapeutics, the company behind CT-132, which it describes as the first FDA-authorized prescription digital therapeutic for the preventive treatment of episodic migraine.

Monthly reports and what’s next

Another interesting part is the upcoming monthly migraine report. It appears designed to pull together biomarker trends, headache frequency, goal progress and lifestyle patterns into a single snapshot that can potentially be shared with a physician.

There is also an “in-the-moment migraine support” section, which hints that Ultrahuman may be planning live episode guidance rather than only preventive tools.

Overall, this looks like one of the more ambitious PowerPlugs yet. The company is clearly leaning into condition-specific health experiences, and migraine support is a sensible place to start given how closely symptoms can tie into sleep, stress and recovery metrics.

A more curved, more “traditional ring-like” design

Exclusive renders from Android Headlines show that the biggest visible change is the shape. The outer surface appears to be slightly more curved compared to the Oura Ring 4, which gives it a softer, more traditional ring profile. Granted, it doesn’t appear to be a huge difference.

A flatter edge can sometimes catch or scrape against surfaces. A more rounded design helps reduce that, which matters for something you wear all day and night. Smart rings are easy to forget about until they scratch something you care about. The Gen 5 ring may also be slightly sleeker overall, although that is not entirely clear from the images.

Beyond that there is, reportedly, a slight change in the colour lineup. Rose Gold is being dropped and replaced with a new Deep Rose finish. It leans more towards a bronze tone rather than a gold tint, which gives it a slightly different character.

Alongside that, the usual options remain. Matte black is still there, likely under the Stealth name. Silver and gold also return. Silver comes in two finishes, one glossy and one brushed, which adds a bit more choice without changing the overall lineup too much.

Charging stays the same, including the bulky dock

Oura is not changing how the ring charges. The same dock-style charger is sticking around, along with the portable charging case.

That second option matters more than it sounds. The dock is not something you want to carry around, but the case makes it easier to top up the ring while travelling. Keeping both options suggests Oura is happy with how this part of the experience works.

Battery life is expected to stay roughly where it is now. So there is no indication of a big jump here.

Sensors are the unknown

The leak does not reveal anything specific about the health tracking features. But the images show the sensor position seems to have changed.

What is also worth noting, Oura has recently filed patents with the US Patent Office that point to where it might be heading. One focuses on measuring blood pressure from the finger, which would be a notable step if it makes it into a commercial device. Another looks at atrial fibrillation detection and ECG, something that is starting to appear in a few competing rings.

There is also work around connecting the ring more directly with other devices, including smart glasses. That suggests the company is thinking beyond a standalone product.

None of this is confirmed for the Oura Ring 5, but it gives some context around what could be in development behind the scenes.

A very long runway to launch

The timing here is just as important as the hardware. The ring is expected to launch in 2027 according to Android Headlines.

However, we spotted a FCC registration from Oura from a few days ago for a “wellness ring”. The confidentiality clause expires in six months which means a product from the company will be dropping by this September. So, unless that’s a different variant of Gen 4, there is a chance we might get the Gen 5 device in 2026.

The post Oura Ring 5 leak reveals design tweaks and Deep Rose finish appeared first on Gadgets & Wearables.

The filing, published earlier today, goes into detail on how a ring can move beyond basic heart rate tracking and toward something closer to clinical relevance. It does not rely on constant monitoring alone. Instead, it introduces a more selective approach designed to improve accuracy without draining battery or overwhelming users with alerts.

A smarter way to decide when to measure

One of the main ideas in the patent is timing.

Wearables that keep an eye out on Afib either track continuously or check at fixed intervals. That sounds sensible, but it creates a problem. Much of the data collected during daily movement is noisy. Walking, typing or even small hand movements can distort optical signals.

Oura’s approach is to wait.

The system evaluates whether the user is still enough and whether the device has good contact with the skin. It uses motion sensors and temperature readings to make that call. Only when those signals suggest stable conditions does it run AFib analysis.

Two-stage detection built around PPG and ECG

The patent also describes a layered detection process.

The first stage relies on PPG, the same optical method already used in most rings and watches. This allows the device to monitor heart rhythm passively and flag potential irregularities.

If something looks off, the system can escalate. It may prompt the user to perform an ECG reading, assuming a future version of their ring supports it. That second step acts as a confirmation layer rather than something that runs all the time.

Cleaning up the signal before making a call

Another part of the filing focuses on how the data itself is handled.

The system builds a sequence of intervals between heartbeats and filters out irregular or noisy segments before running classification. This is important because AFib detection depends heavily on pattern recognition, not just raw heart rate.

There is also mention of adaptive parameters and classifier-based analysis. That suggests the system could adjust how it interprets signals depending on the situation, rather than relying on fixed thresholds.

In simple terms, it is not just looking for irregular beats. It is trying to understand whether those irregularities actually point to AFib.

Where Oura stands today

At the moment, Oura does not offer AFib detection as a feature. Its ring focuses on heart rate, heart rate variability and sleep metrics. These can sometimes highlight unusual patterns, but they are not designed to diagnose arrhythmias.

Other smart ring makers have already started moving in this direction. Ultrahuman and Circular both offer forms of AFib detection, signalling that the category is beginning to expand beyond general wellness tracking.

This patent suggests Oura is working on its own answer, but with a slightly different angle. Instead of pushing constant detection, it is trying to improve reliability by being more selective about when measurements happen.

Of course, patents do not guarantee products, but this one feels grounded in real constraints.

How to use

Once installed, a small icon appears in the top right corner. Tapping it opens a new environment built around a chat interface. The first time you access it, there is a prompt to accept terms and conditions.

From there, the experience feels familiar if you have used AI assistants before. You type a question and get a response grounded in your own data. The difference here is context. Jade pulls from multiple streams including sleep tracking, recovery markers, metabolic data and potentially external inputs like lab results if those are connected.

The screenshots below show how this plays out in practice. A user can ask something like how their sleep is trending or whether a particular biomarker is affecting recovery. The system responds with a structured explanation, highlighting what stands out and what looks normal. It even breaks down specific markers such as vitamin D or homocysteine and ties them back to recent sleep performance.

Two modes and deeper analysis

Ultrahuman splits the experience into two modes, which gives a clue about how they see people using this. There is a standard mode for quick answers and a deeper research mode that leans more on structured medical knowledge and evidence.

That second layer is interesting. It suggests the system is not just summarising your data but trying to place it in a broader physiological context. Whether that holds up in real world use will depend on how accurate and cautious those interpretations are, but the intent is clear.

Our takeaway

Jade was first mentioned when Ultrahuman Ring Pro was announced a few weeks ago. But the AI platform is available to owners of the predecessor generation smart ring, as well.

A lot of companies are heading in this direction. The value is moving away from raw metrics and toward interpretation. Users do not just want to see their sleep score or heart rate variability. They want to understand what to do with it. Jade is an attempt at solving that for Ultrahuman ring.

The post Jade AI lands on Ultrahuman Ring bringing chat based health analysis appeared first on Gadgets & Wearables.

There are a few ways to read this, and none of them point to the feature simply disappearing.

Beta is ending but not necessarily the feature

The message being sent to users is quite direct. The beta ends on March 31st and the feature will no longer be available in its current form. That sounds abrupt, but it is actually quite typical for health features that rely on calibration and algorithm tuning.

Blood pressure estimation on wearables is not a straightforward sensor readout. It relies on indirect signals, usually pulse transit time or similar metrics, combined with calibration data. That means beta periods are often used to collect large datasets and refine models before a wider rollout.

From that perspective, ending the beta can just mean one thing. The data collection phase is done.

Timing lines up with a wider rollout

The October 2025 start date for the beta gives it a reasonable window to gather enough variation across users, conditions and daily routines. Shutting it down at the end of March creates a clean break before whatever comes next. That could be a reworked version of the feature, possibly with tighter calibration requirements or improved consistency.

It is also worth noting that companies rarely keep a beta running indefinitely if they plan to ship the feature more broadly. At some point, they need to lock the model and move to a production version.

Where does this leave Gen 2 devices

But who actually gets the feature. This is where things get less clear. If blood pressure was already running on existing hardware during the beta, that suggests Gen 2 devices are technically capable of supporting it.

The question is whether RingConn wants to keep it there.

There are two competing incentives. On one hand, rolling it out to existing users builds trust and adds value to devices already in the wild. On the other hand, blood pressure is a headline feature that can help sell new hardware.

A middle ground is possible. The company could bring a basic version to Gen 2 while reserving a more refined or easier to use implementation for newer devices.

Gen 3 already points to the answer

The strongest clue comes from the upcoming Gen 3 ring. That device is already being positioned with blood pressure tracking as one of its key capabilities.

That makes it unlikely the feature is being abandoned. It is more likely being held back for a more controlled launch.

There is also a practical angle. If Gen 3 includes changes to sensor layout or signal processing, the algorithms developed during the beta might perform better on that hardware. In that case, RingConn may choose to align the full rollout with the new device.

The most likely scenario is a relaunch rather than a disappearance. The beta ends, the feature goes away temporarily, and then returns in a more polished form.

That could happen as a software update for existing users, or it could arrive alongside Gen 3 as a flagship capability and then trickle down later. Either way, it probably won’t be long before we find out. But to us it looks like RingConn has gathered what it needed and is now preparing the next step.

The post RingConn ends blood pressure beta as next phase comes into focus appeared first on Gadgets & Wearables.

This apparently comes after Ultrahuman made changes to the hardware. The redesign was aimed at getting around the patent dispute that had earlier stopped the company from importing its wearables into the United States.

The company had already secured FCC clearance in February. And CEO Mohit Kumar confirmed in an interview with TechCrunch a few weeks ago, that the Ring Pro was submitted to U.S. Customs and Border Protection for clearance. It appears they have that approval now, although this is yet to be confirmed officially by the company.

A reported return to the american market

Federal authorities letting the Ring Pro back into the country could be a big moment for Ultrahuman. For months the company couldn’t ship fresh inventory into the country after Oura won its case at the International Trade Commission. Some existing units were still being sold, but the longer term future depended on showing that the new hardware was different enough from the designs covered by that earlier ban.

The CapTable report says a senior company executive confirmed that Customs and Border Protection has given them the green light. That likely means regulators accepted the redesigned internal setup as something that doesn’t violate the patents involved in the dispute. This kind of route isn’t unusual in tech disputes, but it can get pretty complicated. Companies basically have to prove their engineering solution avoids the specific patented methods that triggered the original import ban.

The technical shifts behind the redesign

The Ultrahuman Ring Pro is the company’s new flagship smart ring with a big focus on battery life and smarter insights. The headline change is endurance.

Ultrahuman says the ring can last up to 15 days on a single charge, which is a big jump for a device this small. The charging case adds up to another 45 days of power, so you can travel for quite a while without needing to plug anything in. The ring keeps the usual health tracking features you’d expect from a device like this, but the company says the internals are faster and more capable than before.  

Software is also a big part of the pitch. Ultrahuman is pushing more AI-driven insights to help interpret your health data rather than just showing raw numbers. The Ring Pro sells for $479 (View On Ultrahuman’s website) that the brand looks very similar to earlier models on the outside, but the upgrades are mostly internal.

Sleep tracking that stops short of the morning

The smart ring spends the night collecting detailed information about how the body moves through sleep. Heart rate behaviour, heart rate variability, movement and temperature patterns help estimate when the body shifts between deep sleep, REM sleep and lighter stages.

The Oura app then turns that data into sleep stage graphs, sleep scores and readiness insights the next morning. Users can see how long they slept, how restorative the night was and whether recovery looks strong enough for the day ahead.

The problem is that the experience largely ends there. The system explains your sleep after the fact but it does not influence the moment you wake up.

For a product built around sleep, that final step still depends on a basic alarm set to a specific time.

Why the timing of waking up matters

Waking from deep sleep often produces the groggy feeling many people recognise when the alarm goes off. Sleep researchers refer to this as sleep inertia. The brain needs time to transition from deep sleep to full alertness.

Waking during light sleep usually feels easier. The body is already closer to wakefulness and the transition tends to be smoother.

A smart alarm tries to take advantage of that. Instead of triggering at one exact time, it watches sleep stages within a preset window before the alarm.

If the body enters light sleep during that window the device triggers the wake signal early. If deeper sleep continues the alarm waits until the end of the window.

The goal is not to shorten sleep. It is simply to wake at a more natural moment within the final stretch of the night.

How Oura could actually wake you up

Oura already gathers all the necessary signals required to support a smart alarm. Those measurements power the sleep stage graphs shown in the Oura app each morning.

A smart alarm would apply that same information in real time. Instead of triggering an alarm at one exact time, the user would set a wake window, for example between 6:30 and 7:00.

During that window the system would monitor sleep stage transitions. When the body moves into light sleep the Oura app could trigger the alarm on the phone. If deeper sleep continues the alarm would simply go off at the end of the window.

This approach would not require any new hardware. The ring would continue doing what it already does, while the phone handles the actual wake alert. What is missing today is the software layer that links the two together.

A small change with practical benefits

Many smartwatches and some smart rings over the years have included some form of smart wake function. Oura has positioned itself as a premium sleep focused device, which makes the absence of this capability stand out even more.

Adding it would turn sleep tracking into something slightly more active. Instead of just analysing the night, the system would help shape how it ends.

That shift might seem minor but mornings are where sleep quality becomes most noticeable. Waking during the right moment of the sleep cycle can make the difference between feeling ready to start the day and spending the first hour shaking off grogginess.

The post A smart alarm feels like the obvious next step for Oura appeared first on Gadgets & Wearables.

That does not mean the two situations are identical. OpenAI was hit by a fast public backlash tied to a fresh headline. Oura’s DoD ties have been sitting in the background for longer. But the overlap is obvious enough to matter. In both cases, the company sits close to highly personal data. In both cases, users are left asking the same basic question, how separate is my everyday product from the government facing side of the business?

Why this matters now

Oura’s defence connection is not a minor pilot or a vague promise of future cooperation. The clearest official record is the October 2024 Defense Health Agency contract awarded to the company.

The contract value was put at $96.1 million and the scope went beyond devices alone. It’s about Oura supplying a broader stack that mixes hardware, software and analytics. Once readers understand that, the DoD link starts to look less like a side project and more like a proper business line.

Oura itself has reinforced that impression. In 2025 the company said the DoD was its largest enterprise customer and tied the relationship to an expanding US manufacturing footprint in Fort Worth, Texas, with operations projected for 2026. When a company starts shaping production around defence demand, it tells you this is not a tiny contract parked off to one side.

What Oura says about your data

This is where the story gets more delicate. We have not seen evidence that ordinary consumer Oura data is being fed into the DoD. In fact, Oura has publicly said the opposite. In its privacy messaging, the company says member data is not for sale and will never be sold or rented to the government. It also says consumer data does not touch its DoD only offering unless the person is a service member enrolled in a relevant program and has consented to share that data.

That is an important distinction and it should not be blurred for clicks. Still, it does not make the story go away. Consumer trust is not shaped only by whether data is technically segregated. It is also shaped by perception, by the company you keep and by how comfortable users feel supporting a brand that works closely with defence agencies. The ChatGPT backlash showed how fast that discomfort can turn into real user action.

There is also the Palantir angle, which helped stir confusion around Oura last year. Oura’s defence messaging referenced Palantir FedStart as part of an IL5 ready hosting environment for government deployments. Later reporting suggested this was not some sweeping strategic partnership but rather a more limited commercial relationship tied to secure infrastructure requirements. Even so, the Palantir name adds fuel to the discussion. People tend to read it as shorthand for surveillance, whether that is fair in each case or not.

The bigger issue for wearables

The more interesting angle here is not whether Oura has done something wrong behind the scenes. But where wearable tech is heading. Devices that started out as personal wellness tools are slowly showing up in places like workforce monitoring, military readiness programs and large institutional health projects.

It is also worth noting that Oura seems to be the only smart ring company with such a connection. Other wearables brands have worked with military research or training programs over the years, but in the smart ring space Oura appears to be the only one with a formal contract and a platform built for government deployments. That makes it a bit of an outlier in the category.

And that shift can create a bit of a trust hurdle. Most people buy a smart ring to track sleep, readiness or recovery. It feels like a personal gadget, something you use for your own health. That feeling can start to change once the same platform also shows up in systems designed for resilience tracking, performance monitoring or wider wellbeing programs inside big organisations. And there is evidence some people are swapping their Oura Rings for other options because of this.

For Oura, the ChatGPT development probably means the defence side of the business will be harder to keep in the background. The company says consumer data is protected and kept separate from its government programs. That may well be enough for a lot of users. The OpenAI situation shows how quickly people can start asking questions once a Pentagon connection enters the picture.
