Most people only find out something's wrong after they feel it.

Circular Ring tracks 140+ biomarkers — ECG, HRV, sleep, stress & recovery — before your body sends you a warning sign.

Kira AI reads all those signals and tells you exactly what your body needs, when it needs it.

How does an ECG fit inside a ring?

Circular Ring 2 uses real ECG electrodes, not light.
1. Close the loop
2. Electrodes contact skin
3. 40s signal capture
4. AI analyzes rhythm
