I’m the developer behind FitMesh.

The latest updates added support for using the app with just a smart ring (no smartwatch required), plus workout recording directly from the app.

If you also wear a smartwatch, the ring and smartwatch can work together in parallel, giving you a unified view of your health data instead of forcing you into a single ecosystem.

I also recently added advanced support for the Colmi R09, and I’m continuing to improve support for both premium and budget smart rings.

I’d love to build the features that smart ring users actually want most, so I thought I’d ask this community.

If you could add one feature, what would it be?

• 📈 Better sleep insights and trends
• ❤️ Heart rate & HRV analysis
• 😴 Smarter sleep score and recovery insights
• 🏃 Better workout tracking
• 🔋 Ring battery health and usage insights
• 🤖 AI-powered health insights
• 📊 More detailed charts and long-term trends
• 🔔 Smarter notifications and reminders
• 👨‍👩‍👧 Family dashboard (compare and monitor multiple users)
• 🌍 Integration with more apps and services
• 💬 Something completely different (I’d love to hear your ideas!)

Also, what’s the biggest frustration with your current smart ring app?

I’m genuinely trying to build something that solves real problems rather than just adding features for the sake of it, so every suggestion helps shape the roadmap.

Thanks in advance for your feedback!

There are so many mixed reviews I have no idea which one is best! I do lift weights which is my main concern about a smart ring. I’m afraid that I will break it lifting. I also do hiit and cardio but I lift 5 days a week. Tracking sleep isn’t a huge deal although it would be nice.

Can someone that lifts weights chime in on which ones best?

Thank you!

I’ve been going back and forth on buying a smart ring for months, and I’ve narrowed it down to Oura, Ultrahuman, and RingConn.

Honestly, I’m so tired of the endless “X is better than Y” posts that turn out to be sponsored or affiliate content. I’d really love to hear from people who have actually used these rings long-term.

My current setup:
I wear an Apple Watch for fitness and workouts.
I can’t sleep wearing my Apple Watch because it’s uncomfortable, so I’d use the smart ring primarily overnight.

What I’m looking for:
Accurate sleep tracking
Stress/recovery insights
Step tracking
Temperature tracking (for illness, cycle tracking, and migraines)
Good data interpretation and actionable insights

My thoughts so far:
Oura Pros:
Seems to have the best app and data interpretation.
Everyone seems to praise the quality of the insights.
Oura Cons:
Most expensive option once you factor in the ring, Oura membership, and (potentially) a Natural Cycles subscription.

Ultrahuman Pros:
No subscription.
I like features like the caffeine window recommendations.
Ultrahuman Cons:
The ring looks a bit bulky to me.
I’ve seen quite a few reports of hardware issues and replacements over time.

RingConn Pros:
Best price.
No subscription.
Slimmer design.
Since I already have an Apple Watch, I don’t necessarily need every premium feature.
RingConn Cons:
The app seems to offer less interpretation of the data.
I struggle to find unbiased, long-term reviews. A lot of what I see online feels sponsored, so it’s hard to know what to trust.

If you’ve used any of these rings (especially for 6+ months), I’d really appreciate your honest opinion. The good, the bad, and the ugly. Bonus points if you use a smart ring alongside an Apple Watch! I’d love to know how the two complement each other and whether you feel one of these rings is actually worth the investment.

Thanks in advance!

Hi does anyone have any Oura ring UK/EU referral codes please

Would I be insane to buy an ultrahuman despite seeing all the negative reviews? I mainly want a ring for cycle and sleep tracking, the step count is a nice bonus. I can't use a smart watch at work because I work with social security numbers and other sensitive information so all electronics with a screen have to stay in the back. From all the research i've done, ultrahuman has the best cycle tracking by far. However the reliability is awful and i've seen recently that they aren't honoring the warranty which is discouraging. It's rough because the reviews are either god awful or great, there is no in between with this product. I wouldn't care about the ring dying and needing a replacement if the warranty was actually honored but as it stands I don't want to get the ring, it breaks and i'm out nearly $500.

I'm somewhat considering getting a sealed one of ebay, they look to be around $200 but there's still the possibility it breaks right away and then I'm out $200 which is still too much to waste. I am also considering ringconn but it isn't as advanced with cycle tracking as far as i'm aware and that's number one priority for me. Does anyone have any advice or insight? I feel crazy for even considering getting an ultrahuman with all the negative rep they have right now.

After 3 failed rings in 3 months I requested a refund and they granted it and arranged for a pick up. However this was over a month ago and I’ve contacted them multiple times since the ring has been returned and I’m yet to receive a refund or a single response to any of my emails.

Hi everyone,

I’m working on an early-stage smart ring research project and we’re looking to talk with a small group of experienced smart ring and wearable users.

We are trying to better understand how people use wearable data day to day: what they check regularly, what they ignore, what actually affects their decisions, and what feels missing from current devices.

The conversation would be remote and take around 45-60 minutes. As a thank-you, selected participants will receive a $50 Amazon gift card.

If you’re open to chatting, please message me with:

1. Which smart ring or wearable you use
2. How long you’ve used it
3. The metrics you usually check
4. One thing you like or dislike about your current device

We are aiming to speak with up to 10 people.

Looking forward to hearing from you😊

Short version: if you own a WHOOP, the band is dead weight without a ~$199–$359/year membership, and all your data lives on their cloud. NOOP is a free, open-source app that talks to your WHOOP directly over Bluetooth and gives you recovery, strain, sleep and a lot more — on your own device, no account, no cloud, no subscription. Your data never leaves your phone or Mac.

It's independent and unofficial (not affiliated with WHOOP). It's been going a while — 171 releases, 10,000+ downloads, 1,600+ GitHub stars — and v4 is the biggest update yet.

⭐ Standout features (the stuff that makes people switch)

• No subscription, ever. Every feature unlocked, no account, no nag. Free forever.
• 100% offline & private. No cloud, no sign-up — your raw heart-rate and sleep data physically stay on your device. You can export all of it whenever you want.
• It runs on a Mac. WHOOP doesn't even make a Mac app. NOOP gives you a full desktop dashboard and a menu-bar live-HR readout.
• NEW in v4 — a longevity engine: your Fitness Age, a Vitality score (0–100) and a Body Age in years, computed from data you already have.
• Your strap can buzz back. NOOP uses the band's own haptic motor for HRV breathing biofeedback (it paces your breath with felt cues) and a silent HIIT interval timer (buzzes every work/rest transition — train hands-free, no screen).
• Turn your strap into a remote. Double-tap the band to lock your Mac, mark a moment, or run any macOS Shortcut.
• Bring your WHOOP history across in ~1 minute by importing your official export — then it's yours.

🆕 What v4 adds — the "Age & Longevity" engine

Three new on-device numbers, all framed honestly as wellness estimates (never a clinical age):

• 🫀 Fitness Age — how fit your heart is vs your actual age, from resting HR + recent activity, built on the published Nes/HUNT VO₂max research. A "How accurate is this?" panel shows exactly which inputs went in.
• ✨ Vitality (0–100) + Body Age — your longevity read, the way WHOOP's "Healthspan" works: resting HR, sleep duration + regularity, HRV and activity each weighed against published all-cause-mortality research. It even names the one habit helping you most and the one holding you back.
• 🏃 Optional VO₂max estimate — add a waist measurement and NOOP shows it alongside your Fitness Age.

(v4.0.1, out today, also makes Today's Effort update live through the day instead of lagging, and fixes a sleep-time-edit bug.)

📋 The full feature list

Daily scores — NOOP's own, all out of 100 to go head-to-head with WHOOP:

• Charge (recovery) from HRV / resting HR / skin temperature / sleep quality
• Effort (strain), now computed live as your day builds
• Rest (sleep) composite, with full sleep staging

The screens:

• Today — home dashboard: recovery ring, a "today's synthesis" insight, stat tiles (recovery, strain, sleep, HRV, RHR, SpO₂, respiratory, steps, weight, calories) each with a 14-day sparkline, live strap battery %, HR trend and recent workouts.
• Readiness — a "should you push today?" call built on real sports science: HRV vs baseline (Plews/Buchheit), resting-HR drift (Lamberts), respiratory drift, training-load balance (acute:chronic, Gabbett) and monotony (Foster) → one headline (Primed / Balanced / Strained / Run down) with the reasons.
• Sleep — hypnogram, stage breakdown, efficiency, resting HR & HRV from the on-device sleep stager. Browse back through past nights, and edit bed/wake times.
• Stress — day-level autonomic-load view. Health — full biometric overview (HR, HRV, SpO₂, skin temp, respiratory rate). Trends — long-range trends across everything.
• Workouts — detected sessions with strain + HR detail, plus GPS workout tracking with route map, HR zones and a post-session summary. Live — real-time HR/frame stream.
• Breathe — HRV haptic breathing biofeedback with pre/post HRV outcome (Relax 4-6, Coherence 5.5, Box 4-4). Intervals — silent haptic HIIT timer.
• Mind — a daily mood check-in correlated against your own recovery/sleep/HRV (on-device, non-clinical).
• Explore / Compare / Insights — interrogate any metric over time, plot two together, and surface correlations from your own data.
• Data Sources — one-tap import of a WHOOP CSV export, an Apple Health export, or a nutrition CSV (Cronometer / MacroFactor).
• Automations — double-tap → Mac action/Shortcut, lock-on-wrist-off, HR-zone haptic coaching, and a smart alarm that arms the strap's own firmware to buzz you awake even if the app's closed.
• Coach — an optional AI coach you can ask about your data in plain language. It's off until you add your own key (Anthropic, OpenAI, or any OpenAI-compatible endpoint including a fully local model via Ollama / LM Studio) — and it only ever sends a short text summary + your question, never raw data. With a local model the conversation never leaves your machine.
• Settings — profile, step calibration, units, the in-app What's new changelog, and an opt-in Experimental section.

Also in the box: Apple Health + Health Connect (reads in, writes your workouts back out), steps, strap battery alerts, rename your strap, a live-HR widget / Dynamic Island / Live Activity, raw sensor CSV export, a menu-bar extra on Mac, a first-run onboarding wizard, and a built-in scoring guide that explains every number and how it differs from WHOOP's.

📱 What devices are supported

Platforms — one feature set across all three:

• macOS (13+) — full app + menu-bar extra.
• Android (8+) — full app, install the APK.
• iPhone / iPad — sideload the unsigned .ipa with AltStore / SideStore and sign it with your own free Apple ID (no App Store, no developer account). Newer and a little less battle-tested than Mac/Android.

Straps:

• WHOOP 4.0 — ✅ the fully supported path: live HR, recovery, strain, sleep, full history offload.
• WHOOP 5.0 / MG — 🧪 live heart rate works on real hardware; deeper overnight metrics (recovery, strain, sleep) are still being reverse-engineered, and the app tells you straight which ones aren't ready yet. (Note: pairing a 5/MG means closing the official WHOOP app first so it isn't holding the Bluetooth bond — there's a guide in-app.)
• Multiple WHOOPs — manage several straps, switch between them, and see what each band can do.
• Generic Bluetooth heart-rate straps (Polar and friends) — early support, with a Devices screen and guided pairing wizards.

♥ Keeping NOOP alive

Full honesty: NOOP is free forever, every feature unlocked, no nag — and it's built and maintained by one person, out of pocket. Keeping up with WHOOP's hardware and firmware takes real time and real test gear. The project continues if the people who use it help fund it.

Donations are crypto-only, on purpose — it keeps the project (and you) anonymous, no names attached. If even a small fraction of those 10,000+ downloads chipped in $50 (a fraction of one year's WHOOP membership), NOOP's future is secure for a long time:

• BTC: bc1qn2gkl7wslwpws06mvazjn2uu689zlkv7kg3kf5
• ETH: 0xd64D508b531c4b1297Ca4023C774e0E97aA67B7F

New to crypto? Cash App / Coinbase / Kraken will have you sending in ~2 minutes. Thank you for keeping an independent, no-subscription project alive. 🙏

I need advice, my Ultrahuman ring is no longer working, it completely stopped syncing today. It had some issues on and off the last two weeks. I followed the chat advice, a hard reset, etc. Despite it being less than 1 year of purchase they are saying there’s nothing they can do and I’m “outside warranty. Advice? Has anyone dealt with this? I’m
shocked they’re saying I’m out of the warranty period, it’s the ring air and I bought it 11/2025. I already contacted my credit card.

I have noticed something interesting.

Two people can have completely different lifestyles, stress levels, sleep schedules and health goals yet many wearables still end up giving very similar recommendations.

Shouldn't health tracking become more personal over time instead of relying on generic averages?

Imagine a smart ring that actually learns your patterns like how you sleep, recover, respond to stress and build habits and adjust its insights accordingly instead of treating everyone the same.

Would that make you more likely to wear a smart ring every day? Or do you think today's wearables are already personalized enough?

my ring battery started dying within hours and it won’t connect to my phone. this happens every couple of months. usually i message customer service through the app and a human employee has to reset the ring on their end.

now there’s an AI bot that handles customer service. i literally cannot contact a real person to help me— no phone number, no email address. the AI bot said it would take 48-72 hours for someone to help me. it’s been 10 days.

Ultrahuman rings are not good enough to have AI handle customer issues. will probably get rid of this thing. don’t buy it.

I'm aware the gen 3 has only been out for about 2 months but so far is the gen 3 worth the extra price? The main features I care about are step, sleep and women's health tracking. The main reason i'm considering paying extra for the 3 is advanced sleep analysis and what appears to be more advanced cycle tracking. Can anyone confirm whether these two are actually better with the 3 and worth the bump in price?

I'm trying to decide what to buy next and would love to hear from people who've actually used these devices.
Current setup:
Apple Watch Series 8

Bevel for interpreting all my health data (which has honestly been surprisingly accurate for me)

I'm considering:
RingConn Gen 3

Oura Ring 4

Whoop (mainly for the new vascular/blood pressure-related insights)

Or simply upgrading my Apple Watch 8 to an Apple Watch 11.

My priorities aren't fitness or sports. I'm much more interested in health monitoring and spotting trends.
A bit of background:
I had postpartum hypertension that came out of nowhere, and although my blood pressure is usually normal now, I've had a few unexplained spikes since. Because of that, I'm quite anxious about cardiovascular health and would really value anything that provides meaningful vascular trends or hypertension-related insights (I know none of these devices actually diagnose or continuously measure blood pressure).

I also have endometriosis and Hashimoto's, so I'm interested in tracking inflammation, recovery, HRV, resting heart rate, sleep quality, temperature trends, etc., to see if I can identify patterns around flares.

Since I already use Bevel, I'm wondering whether a ring would actually add meaningful data, whether Whoop's vascular features are worth the subscription, or whether the Apple Watch 11's new health features make it the better upgrade.
If you were starting today, which would you choose and why?
