Sensors
The finger says more about the body than the wrist.
The blood vessels in your finger lie close to the skin, so the ring picks up a cleaner signal than a watch. Inside are a multi-wavelength PPG optical sensor, a skin temperature sensor, and a 3D accelerometer.
Night tells the most: resting heart rate, HRV, oxygen saturation, and temperature measured during sleep show how well you’re really recovering.
- PPG Multi-wavelength optical sensor: heart rate, HRV, SpO₂.
- Temperature skin temperature sensor.
- Movement 3D accelerometer: steps, activity, sleep stages.

Trends from recent days show whether you are heading in the right direction.
