Hi Product Hunt, I'm Anton, the solo developer behind Horef Rings.

I wanted weather, battery and how I slept in the place I look most, my watch face, without a stack of single-purpose apps. So I built it: any of 75 metrics (weather, activity, sleep, health, device, workouts) can be its own complication on any face, and on faces with a large rectangular slot you can put three in one field. The same metrics are available as iPhone Lock Screen and Home Screen widgets.

The part I'm most curious about is Headroom, a daily 0-10 score from last night's sleep, overnight HRV, resting heart rate, breathing and wrist temperature against your own 28-day norm, plus recent activity. It's my own estimate, calculated on your devices. It is not Apple's Readiness score and not a medical measurement, and the method is written out in the app and on the site.

Works with any Apple Watch on watchOS 11+ and an iPhone on iOS 18+. Free to download (date, time, battery, steps and Activity arcs stay free), 14-day trial of everything, then Pro is a one-time $4.99. No subscription, no account, no ads, no analytics. English, Russian, German, French and Japanese.

I'd love to hear which metrics are missing and where Headroom feels wrong to you. I'll answer every comment today.
