Buying guide
Bracelet or Ring?
Both wearables run the same app and cover the same health basics — 24/7 heart rate, SpO₂, HRV, stress and sleep. The bracelet is the training partner: 50+ workout modes with built-in GPS and up to 7-10 days of battery. The ring is the recovery specialist: lighter, quieter, at its best while you sleep.
Two questions
The choice is short
If you run, ride, swim and lift in the same week, the BG02 bracelet is the pick — 50+ workout modes with built-in GPS, a screen-free strap that gets out of the way, and up to 20 days of battery.
The ring wins the night: lighter on the finger than a strap on the wrist, with deeper sleep staging and a morning readiness score. It auto-detects activity instead of logging workouts.
Take the BG02 at $49.99 if training is the main event. Take the Signature ring at $99.99 if recovery is. Many owners wear both — training load on the wrist, recovery on the finger, one app, one picture of the body.
