What Makes the R09 Different

Every feature below is built into the base price — no premium tier, no add-on subscriptions.

24/7 Heart Rate

A continuous optical heart-rate sensor tracks your pulse throughout the day and night, visible anytime in the app.

Sleep Tracking

Automatic sleep detection generates a full report every morning — no need to manually start or stop tracking.

5ATM & IP68 Waterproof

Shower, swim, or sweat through a workout without a second thought — rated to withstand water pressure equivalent to 50 meters depth.

39 Days of Battery

A single charge lasts up to 39 days. The included charging case adds up to 13 extra charges on the go, for up to 60 days of total use between plugging into a wall.

4.4 Grams

Lighter than a standard paperclip, with a concave steel profile designed to disappear on your hand.
