## Long description

Ultrahuman Ring AIR is a compact smart ring designed for continuous sleep and fitness monitoring. The ring uses infrared photoplethysmography (PPG) sensors to measure heart rate and blood oxygen (SpO2) from the finger, offering a slim round gold form factor and a lightweight build that prioritizes comfort for overnight and all-day wear. With a 24 mAh lithium polymer battery it delivers up to 6 days of typical use and pairs with Android devices (Android 6.0 and later) via Bluetooth 5.0.
Advantages
The finger-based sensor placement provides higher blood flow and greater arteriole density than wrist-worn devices, which improves accuracy for sleep and recovery biomarkers. At just 2.4 grams and a slim profile, the ring is designed for minimal interference with sleep and daily activities. Built-in monitoring delivers sleep staging, an everyday sleep score, continuous heart-rate tracking and SpO2 measurement without a recurring app fee for standard features.
Suitable for
Users who prioritise accurate sleep and recovery monitoring
People who prefer lightweight, unobtrusive wearables for overnight use
Fitness enthusiasts wanting continuous heart-rate, activity and calorie tracking
Anyone tracking SpO2 and HRV trends for wellness insights
When it may not be suitable
The ring is not intended to replace medical-grade equipment or provide clinical diagnoses; its measurements are for wellness and fitness insights. Individuals who require continuous on-demand monitoring for medical conditions should consult a healthcare professional and consider medical devices designed for clinical use.
