## Long description

The Ultrahuman Ring AIR is a slim smart ring designed for continuous sleep and fitness monitoring. Housed in a round gold form factor, it combines infrared photoplethysmography (PPG) SpO2 sensing with heart rate and activity tracking to deliver fingertip biomarker data. The ring is lightweight and compact, with a LiPo 24 mAh battery that provides up to 6 days of typical runtime and physical dimensions of approximately 8.1 mm width and 2.45 mm thickness. Compatible with Android 6–13, it offers standard monitoring features without requiring a paid app subscription.
Advantages
Finger-based PPG and SpO2 sensing provide higher blood flow and arteriole density than wrist devices, which improves the accuracy of sleep stage detection, heart rate variability (HRV) and skin temperature trends. At about 2.4 grams and a slim profile, the ring is designed for comfortable day-and-night wear with a hypoallergenic inner lining. The combination of continuous sleep analysis, activity tracking and a multi-day battery life makes it a compact, all-in-one wellness companion.
Suitable for
Continuous sleep tracking and sleep stage analysis
Daily activity logging (steps, active minutes, calories)
Basic cardiovascular and recovery monitoring using HR and HRV
Users seeking a low-profile, lightweight wearable for 24/7 use
When it may not be suitable
The Ultrahuman Ring AIR provides detailed trend and recovery metrics but is not a medical diagnostic device and should not replace professional medical monitoring or treatment. Users requiring advanced sports metrics, GPS-based distance tracking, or extensive third-party app integrations may find the ring’s feature set limited compared with dedicated multisport watches.
