## Summary description

It features infrared photoplethysmography (PPG) for blood oxygen and heart‑rate related measurements, a round black form factor, USB‑C charging, a 24 mAh LiPo battery with up to 6 days runtime and an 8.1 mm width. Intended for continuous wear to track sleep stages, recovery and daily activity without a recurring app fee for standard features.

## Long description

Ultrahuman Ring AIR is a compact smart ring activity tracker in size 7 designed for continuous sleep and fitness monitoring. The ring uses infrared PPG sensors to measure blood oxygen and heart-rate related metrics, tracks sleep stages and daily movement, and offers up to six days of battery life with USB‑C charging. Its lightweight, round black design and passive monitoring aim to provide nightly recovery scores, AFib detection, and insights into circadian alignment and productivity without a recurring app fee for standard features.
Advantages
The ring provides detailed, night-by-night sleep analysis including sleep stages, sleep score and sleep debt, alongside daytime activity tracking such as steps, distance and calories. It offers dynamic recovery scoring that combines sleep, HRV, skin temperature and stress rhythms, plus cardiac analysis tools like tachograms and Lorenz plots. Additional features include AFib detection, VO2 Max estimation, caffeine and vitamin D timing suggestions, and screentime impact tracking — all in a small, waterproof device with Bluetooth 5.0 connectivity and up to six days of battery life.
Suitable for
People who want continuous, passive monitoring of sleep and recovery
Fitness-minded users tracking steps, calories, workouts and VO2 Max trends
Users looking for nightly heart rhythm monitoring including AFib alerts
Those who prefer a compact, wearable tracker with multi-day battery life
When it may not be suitable
The Ultrahuman Ring AIR provides many health and wellness insights but is not a substitute for professional medical diagnosis. While it offers AFib detection and medical-grade nightly reports, users with known heart conditions should rely on their healthcare provider for definitive assessment and treatment. The ring’s measurements depend on proper fit and skin contact; intermittent wear or an incorrect size can reduce data accuracy.

How to use
Wear the Ultrahuman Ring AIR on the recommended finger snugly so the sensors maintain good skin contact.

Use the app to set up personal details, view nightly sleep reports, recovery scores, heart rhythm summaries and daily activity metrics. For best results keep the ring on continuously, especially at night, and recharge before the battery is depleted.
What to consider before purchase
Ensure the ring size (Size 7) fits your finger for accurate readings
Understand this device provides wellness insights and is not a replacement for medical diagnosis
Check that your smartphone supports Bluetooth 5.0 and the Ultrahuman app
Consider charging habits for up to 6 days of battery life between charges
Usage recommendations
