## Long description

The Ultrahuman Ring AIR in Grey is a compact smart ring activity tracker designed for daily health, sleep and fitness monitoring. Lightweight and low-profile, it combines infrared PPG SpO2 sensing with continuous heart-rate and movement tracking to give an overview of sleep quality, recovery and daily activity. The ring is powered by a 24 mAh LiPo battery with up to 6 days of runtime and charges via USB‑C. It supports Android and iOS and is sized for comfortable all-day and night wear.
Advantages
The ring’s very light and slim form factor makes it comfortable to wear around the clock while remaining discreet. It provides consolidated sleep metrics including a Sleep Index, continuous heart-rate monitoring, skin temperature trends and SpO2 measurements using infrared PPG. Additional movement and HRV insights support recovery and metabolic activity tracking. Bluetooth connectivity enables seamless syncing with compatible mobile devices.
Suitable for
Sleep tracking and nightly sleep quality assessment
Daily activity and step/movement monitoring
Heart-rate, HRV and recovery insight tracking
Monitoring skin temperature trends and SpO2 for basic wellness signals
Users who prefer a discreet wearable for 24/7 use
When it may not be suitable
The Ultrahuman Ring AIR provides wellness and activity metrics but is not a medical device and should not replace professional medical equipment or diagnostics. Users requiring clinical-grade SpO2 or heart-rate data for medical decisions should consult healthcare professionals and use certified medical devices. Its small battery capacity supports several days of use, but very frequent heavy use or continuous sensor activity may reduce runtime between charges.
