Overview
The Ultrahuman Ring Air is an ultra-lightweight smart ring focused on sleep and recovery tracking. While it offers no subscription fees and impressive specs on paper, widespread reports of premature battery failure and hardware issues make it difficult to recommend.

- No subscription fees
- 100m water resistance
- Sleep and recovery tracking
- Heart rate and SpO2 sensors
Description
The Ultrahuman Ring Air launched as an Oura Ring competitor with a compelling value proposition: similar health tracking capabilities at the same price point, but without the monthly subscription. The titanium ring weighs just 2.4-3.6g depending on size, making it nearly imperceptible during wear. However, community feedback reveals significant hardware reliability issues including premature battery failure, battery bloating, and scratching problems that undermine the product's long-term value.
