Smart Ring R10

Wear your health data — invisibly. The Smart Ring R10 fits like a sleek wedding band and tracks heart rate, sleep stages, body temperature, respiration rate, daily steps, calories and stress through clinical-grade infrared and red-light sensors. The titanium-coated stainless steel shell is hypoallergenic, waterproof to 100m and weighs less than 4 grams. Battery life of up to 7 days on a single charge, plus a thumb-sized magnetic charger that's easy to travel with. The companion app uses on-device AI to compute readiness, sleep and recovery scores each morning — guiding you on whether to train hard, rest, or focus on hydration. Pairs with iOS and Android, supports Apple Health and Google Fit. Size chart kit available before purchase ensures perfect fit.
