I was on the fence between Ringconn Vs Oura Vs Ultrahuman. I ultimately decided on the UH ring for a few reasons.. 1. Superior temperature and cycle tracking. 2. Easy to use, interactive, FREE to use app. 3. No monthly fees such as Oura ring. This ring is comfortable to wear while sleeping, it tracks sleep best, too. The workout tracking feature needs a bit of work but I have my Apple Watch for that. It charges quickly, and needs recharged about every 4 days (it keeps collecting data even in low battery mode and then syncs to the app once charged). I have never had any issues with the sync not functioning minus when I went out of the country and didn’t have Bluetooth connectivity. A soft reset quickly resolved that issue. All in all, the hardware and software of the ring are super easy friendly for someone not tech savvy, and it’s comfortable enough to wear 24/7 and tracking your health without looking obvious - just a fashion statement to those who don’t look closely. Don’t regret the cost for even a MOMENT!

Love the ring and the product. It does exactly what it says it will do. The ring size kit was worth it, definitely get one of those if you're unsure. Fits perfecting on my index finger. Love the color, the app is easy to use, so far the waterproof feature has been on point and the sleep tracking is very accurate. I have also worn it while indoor climbing and lifting but I tape over it to avoid scratches or damage which was worked; thus the durability has been very good so far.

I've had the ring for a bit and I have some thoughts! POSITIVES - lightweight, you barely feel it - great stats -- sleep stats + workout mode + period tracking are really really accurate! also the stress monitor + HR - an incredible amount of workouts that help you pick the best or most accurate choice for the one you will be doing - stunning finish and color - waterproof is great - actual ring size is super accurate to the sizing kit! NEGATIVES - scratches fairly easily - battery life needs a lot of improvements. I alternate between turbo + chill and battery lasts around two and a half -- three days - sometimes the app syncing takes a bit. - does not have a "you might be getting sick" warning like other products do - you can't be too far from your phone when working out because then the ring won't track the workout properly. I find this to be very annoying. My ring also randomly died after two and a half months it literally would not connect to the app and I could not troubleshoot it. UH customer service was great with replacing, but it does make me hesitant to continue recommending this. Do your research before buying! My experience has been pleasant, but proceed with caution.

The experience so far Rating: ★★★☆☆ (3/5) Verdict: Ambitious and data-rich, but still feels like a beta product. The Ultrahuman Ring AIR is a sleek, health-focused wearable that offers impressive insights and a visually premium app experience. But while it sounds like the perfect fitness and recovery tracker on paper, real-world performance exposes its inconsistencies, quirks, and growing pains. ⸻ ✅ What It Does Well • Extremely detailed health data: It tracks heart rate, HRV, sleep, recovery, and more—and explains each metric clearly. It’s not just data-heavy, it’s educational too. • No subscription required (unless you want extras): Unlike Oura or others, you get full access to your health data right out of the box. Ultrahuman’s optional “Power Plugs” (a.k.a. add-ons) cost $2–$4/month depending on the feature and offer deeper insights without being essential. • FSA/HSA eligible: If you’ve got leftover HSA/FSA funds, this is a good end-of-year purchase. You can even use those funds on monthly Power Plug subscriptions. • Well-designed app: The interface feels high-end and becomes intuitive after a few days. Charts, graphs, and summaries look great and are easy to follow. • Quick charging & useful warranty support: I typically charge it while showering in the morning. When my partner’s ring began dying within 2–3 hours, Ultrahuman replaced it quickly—though it’s unclear if that was thanks to the protection plan or internal diagnostics they ran that determined the replacement was needed. • UltrahumanX protection plan is fair: It covers lost rings, battery failure, and even resizing if you lose weight. Worth it only if you get the ring on sale (we paid $230 each with stacked discounts—very fair compared to MSRP). ⸻ ⚠️ Where It Falls Short • Accuracy concerns: I’ve seen heart rate spikes to 172 bpm while sitting, even though my Apple Watch showed a steady 67. Step count is wildly inflated during non-walking workouts like rowing—Apple logged 50 steps, while the ring claimed over 1,000. • Unreliable sleep tracking: Waking up briefly can reset your sleep record, and some nights it reports only 2 hours of sleep when I clearly got 7+. This skews recovery scores into the red zone, making the insights less useful. • Battery life isn’t as promised: Ultrahuman advertises 4-6 days—but I consistently get 2–3 and half days unless I enable “Critical Power” mode. Even the in-app battery test is misleading—it assumes the length because of trickle charging it daily, which defeats the purpose of true 6-day battery life off one charge. • Power modes are poorly optimized: “Turbo,” “Chill,” and “Critical Power” sound great—but switching between them takes over a minute. Chill mode only disables one feature and barely extends battery life, while Critical Power mode helps significantly but cuts off most functions. • Slow syncing: Syncing data often takes 5+ minutes, even when the ring is connected via Bluetooth. Sometimes it’s immediate, other times painfully slow. The app’s troubleshooting suggestions (“restart phone,” “turn off Bluetooth”) feel like filler rather than real diagnostics. • Too many notifications: Even on the lowest setting, I get 3–6 alerts every 45 minutes—way more than my smart watches, which average 1-3 every few hours. (These are health notifications, like the “stand up your sitting too long” or “check how close you are at closing your health rings”) • Material feels questionable: Marketed as titanium, but the ring is very lightweight and makes a plastic-like sound when dropped—not what I’d expect from metal. Especially when you compare it with an actual ring, I was expecting a little more heft to it. • Platform inconsistencies: Some features behave differently depending on the OS. For example, Android shows the last known location with an address for “Find My Ring,” while iOS does not. ⸻ 🤔 Other Notes & Suggestions • Feels like an early beta: Ultrahuman sent an email thanking me for being an early adopter—which confirms what the experience already suggests: this is a version 1.0 product still working out kinks. • Basic diagnostics: Battery and syncing diagnostics in the app feel underdeveloped. They don’t offer deep troubleshooting—just basic “restart” suggestions. • App needs customization: I only have the ring, so it’s annoying to see tabs for other Ultrahuman products I don’t own. I’d love the ability to customize the dock to just show “Ring,” “Profile,” and “Zones.” • Power Plug layout is clunky: Some insights with limited value (like “You’re a consistent sleeper”) take up large card space, while more important metrics are squeezed into small strips. Being able to resize or pin these like widgets would drastically improve usability. ⸻ 💬 Final Thoughts The Ultrahuman Ring AIR shows promise—it’s attractive, feature-rich, and offers meaningful health data for people who want to understand their body better. But right now, it feels like a work-in-progress. Syncing delays, battery inconsistency, and unreliable tracking make it hard to fully trust. If you catch it on sale (and maybe use an HSA/FSA account), it’s a worthwhile experiment—especially if you value form factor over full smartwatch capabilities. But if you’re looking for something polished, dependable, and accurate out of the box, you might want to wait for a new ring air version 2.0 or a few more software updates.

I had a hard time choosing a smart ring, but I’m very happy I went with the Ultrahuman Ring. It checks all the boxes I was looking for: lightweight, stylish, water-resistant, and packed with useful features in the app. I have arrhythmias and like that I can track my heart rate without always wearing my Apple Watch. The data has been surprisingly accurate and comparable to what I get from my watch. I got the gold color and love how it looks, sleek and trendy. I definitely recommend ordering the sizing kit first. I guessed my size and was wrong, but thankfully the return and exchange process was smooth. I’m tough on my hands (mom of two young kids), and the ring has held up well so far. If you're looking for a less intrusive, functional alternative to a smartwatch, this is a great option. Plus, being able to use my HSA made it an easy decision. Without that, I might not have bought it, but I’m so glad I did.
