I’ve been using the Ultrahuman Ring Air for a few weeks now, and I’m genuinely impressed! The build quality is excellent — the titanium body feels premium, lightweight (~4–5g), and extremely comfortable for 24/7 wear, including sleep. The ring’s sensors are precise, and the indentation placement on the underside of the finger makes heart rate, HRV, and SpO₂ tracking very accurate.I love how it automatically detects sleep, naps, and circadian patterns without having to turn on any sleep mode, unlike other devices I’ve used. The Dynamic Recovery Score is super insightful, helping me plan workouts and manage recovery effectively. Even if I don’t wear my Apple Watch at night, the ring logs all sleep and recovery metrics directly into Apple Health, which I can view in my phone’s sleep and vitals widgets.It integrates seamlessly with Apple Health, so steps, calories, and workouts from my Apple Watch show up in the timeline. For gym sessions, I sometimes wear the ring on my non-dominant hand or take it off during heavy lifting to protect it — the combination of the ring for recovery and the Watch for workouts is perfect.The ring is durable, water-resistant (safe for showers, handwashing, and swimming), and the optical sensors are completely safe — the green/red flickering lights are low-power and non-harmful. I also appreciate that it requires no subscription to get full features.Overall, the Ultrahuman Ring Air is an excellent investment for anyone serious about tracking recovery, sleep, HRV, and overall wellness alongside other devices. Highly recommend!
