## Long description

The Ultrahuman Ring AIR is a slim smart ring activity tracker designed for sleep and fitness monitoring. In a gold round form factor it houses sensors for continuous heart-rate monitoring, infrared photoplethysmography (PPG) for blood oxygen (SpO2) measurement, and motion tracking. With a thin profile (8.1 mm width, 2.45 mm thickness) and a lightweight construction, the ring is intended for all-day and overnight wear and provides up to six days of battery life from a 24 mAh LiPo cell. It offers sleep-stage analysis, recovery scoring and activity tracking without a recurring app fee for standard features.
Advantages
The Ultrahuman Ring AIR delivers fingertip-level biometric accuracy using PPG sensors and an SpO2 channel, which improves the precision of heart rate, HRV and skin-temperature-related metrics compared with many wrist-worn devices. Its featherlight design (approx. 2.4 g) and hypoallergenic interior make it comfortable to wear continuously. The slim profile and gold finish provide a discreet, wearable form that balances durability and everyday aesthetics. Built-in Bluetooth 5.0 enables wireless syncing with compatible Android devices.
Suitable for
Tracking sleep stages and daily sleep quality
Monitoring heart rate, HRV and blood oxygen during rest and daily activities
Everyday activity tracking: steps, distance, calories and active minutes
Monitoring recovery and adapting rest or light interventions like naps and breathwork
When it may not be suitable
The ring is intended primarily for general wellness, sleep and fitness monitoring and is not a medical device; it should not be used for clinical diagnosis or emergency decision making. Users who require continuous, medical-grade monitoring or who rely on dedicated medical equipment should consult healthcare providers and consider clinically certified devices.
The ring’s compatibility depends on supported Android versions for full functionality; users of unsupported operating systems or those needing advanced smartwatch features beyond sleep and recovery tracking may find it limiting.

How to use
Wear the Ultrahuman Ring AIR on your finger snugly but comfortably; ensure the inner sensor surface maintains contact with the fingertip for accurate readings. Install the companion app on a supported Android device and pair the ring via Bluetooth 5.0 to enable data syncing. Use the app to view sleep-stage breakdowns, daily recovery scores and activity summaries. Charge the ring using the supplied charger when the battery is low; typical runtime is up to six days depending on usage and settings.
What to consider before purchase
Confirm compatibility with your smartphone’s OS version and Bluetooth support
Choose the correct ring size to ensure sensor contact and comfort
Understand that the device is for wellness monitoring and not a medical diagnostic tool
Battery runtime varies with feature use; heavy continuous monitoring may reduce days of operation
Usage recommendations
For consistent sleep and recovery insights, wear the ring continuously including overnight and sync it regularly with the app. Maintain a snug fit on the finger used for sleep tracking, keep the sensor surface clean, and charge the ring periodically to preserve continuous monitoring. Use recovery scores and sleep-stage data to guide rest periods, short naps, or breathing exercises rather than to make clinical decisions.
