## Long description

The Ultrahuman Ring AIR is a compact smart ring designed for sleep and fitness monitoring for both men and women. In a slim black round form with an 8.1 mm width, it integrates an infrared PPG blood oxygen (SpO2) sensor, continuous heart‑rate monitoring and activity tracking. The ring is powered by a 24 mAh LiPo battery with up to 6 days of typical runtime and recharges via USB‑C. Standard features work without an app subscription.
Advantages
The ring provides fingertip biomarker readings for improved accuracy compared with wrist devices, delivering precise measurements of sleep stages, heart rate variability (HRV) and skin temperature. At approximately 2.4 g and with a hypoallergenic inner lining, it is built for near‑continuous wear and user comfort while maintaining a slim, durable design. Integrated Bluetooth 5.0 enables wireless syncing with your device.
Suitable for
People who want detailed sleep stage tracking and daily sleep scores
Users seeking continuous heart rate and HRV insights for recovery monitoring
Active individuals who want lightweight activity tracking and workout monitoring
Anyone preferring a discreet, ring‑style wearable instead of a wrist device
When it may not be suitable
The Ultrahuman Ring AIR may not be suitable if you require medical‑grade measurements or certified medical device status; it provides consumer wellness data rather than clinical diagnostics. It may also be less suitable for users who prefer a larger display or direct on‑device interaction, since the ring relies on a paired smartphone for detailed visualization and settings.
