Overview
The Biemha VR11 is a subscription-free smart ring that tracks sleep, steps and heart rate for both women and men. This size 8 listing comes in silver and pairs with iOS and Android through the companion app.
Ring sizing is unforgiving compared to a watch band, so Biemha pushes buyers hard toward its size chart before checkout to avoid returns. Battery claims also shift depending on where you read them: the bullet points describe 2 to 3 days per charge, stretching toward 5 days only when the included charging case tops it up along the way. Treat the 5-day figure as a charging-case number, not a single-charge one.
- IP68 waterproof rating
- No subscription required
- Heart rate sensor every 30 minutes
- IOS and Android app compatible
Who it's for
Fits someone who wants basic sleep and activity tracking without wearing a bulky watch or paying a monthly app fee. Less suited to anyone who wants continuous, real-time heart rate rather than a reading every 30 minutes.
Pros and cons
- No app subscription or hidden fees
- Rated IP68 water resistant for workouts and swimming
- Lightweight ring form factor vs a watch
- Battery needs case top-ups for 5-day claim
- Heart rate reads every 30 minutes, not continuously
- Correct finger sizing is essential before buying
Performance notes
The ring's sensors take a heart rate reading automatically every 30 minutes while worn rather than monitoring continuously, then feed sleep-cycle and activity data to the companion app. It draws on a claimed 2 to 3 day charge cycle, with the bundled charging case extending that to roughly 5 days across a full case cycle.
