## Long description

Ultrahuman Ring AIR is a compact smart ring in a round silver form factor designed for continuous wear to monitor sleep, recovery and daily activity. Sized 5 and intended for both men and women, the ring uses infrared photoplethysmography (PPG) to measure blood oxygen (SpO2), heart-rate related metrics and skin temperature, and pairs with Android devices. A 24 mAh LiPo battery provides up to 6 days of operation, enabling multi-day tracking without frequent charging.
Advantages
The Ultrahuman Ring AIR provides fingertip biomarker readings that offer higher precision than many wrist-worn devices due to greater blood flow and arteriole density in the finger. It is exceptionally lightweight (about 2.4 g) with a hypoallergenic inner lining for comfortable day-and-night wear, and consolidates sleep, recovery and activity metrics into a single wearable. Dynamic Recovery analysis and daily sleep scoring give actionable insights to improve rest and recuperation.
Suitable for
People who want detailed sleep stage tracking and daily sleep scores
Users seeking recovery and stress-resilience insights (HRV, skin temperature)
Those preferring a low-profile, lightweight tracker instead of a smartwatch
Individuals tracking daily activity metrics such as steps, distance and calories
When it may not be suitable
The ring is sized (Size 5 in this listing), so it may not fit users who require a different ring size; proper sizing is essential for accurate PPG readings. It relies on PPG at the finger and mobile pairing for full functionality, so users expecting medical-grade diagnostics or standalone advanced features without a paired device should consider this limitation.
Key specifications
Form factor: round silver smart ring, Size 5
Sensors: infrared PPG for heart-rate metrics and SpO2, skin temperature sensing
Tracked metrics: heart rate, heart rate variability (HRV), blood oxygen (SpO2), sleep stages and sleep score, activity (steps, distance, calories), hours slept
Connectivity: Bluetooth 5.0
Battery: Lithium Polymer (LiPo) 24 mAh, up to 6 days typical use
Weight: approximately 2.4 grams
Compatibility: Android devices (pairing required for full functionality)
How to use
Wear the Ultrahuman Ring AIR on the selected finger with a snug—but comfortable—fit to ensure consistent sensor contact. Pair the ring with a compatible Android device using the Ultrahuman app to enable continuous data sync and access detailed sleep, recovery and activity reports. Charge the ring periodically using the supplied charger to maintain up to six days of operation; follow the app prompts for firmware updates and calibration if available.
What to consider before purchase
Confirm the ring size (Size 5) fits your finger—proper fit affects measurement accuracy
Requires pairing with an Android device for full feature access
Not a medical device; intended for wellness and fitness monitoring rather than clinical diagnosis
Usage recommendations
For best results, wear the ring continuously, including overnight, keep the sensor area clean, and follow app guidance for charging and firmware updates. Use the daily sleep score and Dynamic Recovery insights to adjust sleep habits, incorporate short naps or breathing exercises, and monitor trends over time rather than isolated readings.
