Frequently asked questions
What does a smart ring track?
Smart rings typically track sleep stages, resting and active heart rate, skin temperature, activity and recovery. Because they sit snugly on your finger, many people find heart-rate and sleep readings more consistent than a loose wrist band.
Do smart rings work with iPhone and Android?
Most smart rings pair over Bluetooth with a companion app on both iOS and Android. Check whether the ring requires an ongoing subscription for full insights before buying, as some brands lock advanced metrics behind a monthly fee.
