RingConn Gen 2 Air
The RingConn Gen 2 Air is a 2.5 g, subscription-free smart ring with a 10-day battery and full sleep and heart tracking — minus the Gen 2's apnoea mode.

★★★★★ ★★★★★ Highly recommended

Watch outs
- Drops the standard Gen 2's sleep apnoea monitoring
- Charges on a desk dock rather than the Gen 2's portable case
- Companion app lacks the polish of Oura and Ultrahuman
