## Long description

Ultrahuman Ring AIR is a round smart ring activity tracker for men and women designed for continuous sleep and fitness monitoring. The Size 11 black ring (8.1 mm width) combines fingertip PPG blood‑oxygen sensing, heart‑rate tracking and skin temperature monitoring with USB‑C charging and a lightweight form factor to deliver detailed sleep, recovery and wellness insights without recurring app fees for standard features.
Advantages
The ring uses fingertip photoplethysmography (PPG) to capture higher‑accuracy biomarker data compared with wrist devices, enabling precise measurement of sleep stages, heart rate variability (HRV), SpO2 and skin temperature. At about 2.4 g and 8.1 mm wide, it is notably light and compact for day‑and‑night wear, with a hypoallergenic inner lining for comfort. Built‑in waterproofing, Bluetooth 5.0 connectivity and up to six days of battery life from a 24 mAh LiPo cell support multi‑day use between charges.
Suitable for
People who want continuous sleep tracking and daily sleep scores
Users seeking recovery and HRV insights to optimise training or stress management
Anyone wanting a low‑profile wearable for all‑day and night monitoring
Those who prefer fingertip accuracy for SpO2 and heart‑rate measurements
When it may not be suitable
The Ultrahuman Ring AIR is not intended to be a medical diagnostic device; it provides wellness and fitness metrics rather than medical‑grade measurements. Users who require clinical‑level monitoring or certified medical devices for health conditions should not rely solely on this ring for clinical decisions.

How to use

Charge the ring every few days depending on usage to maintain up to six days of battery life.
What to consider before purchase
Not a medical device—intended for wellness and fitness insights, not clinical diagnosis
Choose the correct ring size (Size 11 in this listing) for accurate sensor contact
Evaluate compatibility with your smartphone and the Ultrahuman app via Bluetooth 5.0
Usage recommendations
For most accurate readings, wear the ring snugly on a finger with good blood flow, keep firmware and the Ultrahuman app up to date, and charge the ring regularly. Use sleep scores and recovery data to guide lifestyle adjustments such as targeted rest, breathwork or short naps.
