## Long description

Ultrahuman Ring AIR is a compact smart ring for men and women designed to monitor sleep and fitness. The ring combines fingertip PPG SpO2 sensing, heart-rate tracking and lightweight comfort to provide continuous insights into sleep stages, recovery and daily activity. It charges via USB‑C, has a narrow 8.1 mm profile and delivers up to six days of battery life for extended wear without frequent recharging.
Advantages
The Ultrahuman Ring AIR uses fingertip infrared PPG sensors to capture blood-oxygen levels (SpO2), heart rate and skin temperature with greater signal quality than typical wrist devices, supporting more accurate sleep and recovery analysis. At approximately 2.4 grams and with a smooth hypoallergenic inner lining, the ring is designed for all-day and overnight comfort. Standard features do not require an app subscription, and the USB‑C charging and multi-day battery life make it convenient for continuous monitoring.
Suitable for
People who want detailed sleep stage and recovery insights
Fitness-conscious users tracking heart rate, active minutes and calories
Anyone preferring a low-profile, lightweight wearable
Users who need several days of battery life between charges
When it may not be suitable
The Ultrahuman Ring AIR is not intended to replace medical-grade devices; it provides wellness and lifestyle insights rather than diagnostic medical results. Users who need continuous on-wrist displays or advanced smartwatch apps and notifications may find a smart ring’s limited display capabilities restrictive.
