It features a round form factor in grey, lithium-polymer 24 mAh battery with up to 6 days runtime, and USB-C charging (cable included). Compatible with Android 8–13 and iOS 15–16. Practical for continuous sleep analysis, heart-rate-aware workouts and daily activity tracking without recurring app fees for standard features.

## Long description

The Ultrahuman Ring AIR is a compact smart ring activity tracker for men and women that monitors sleep, recovery and daily fitness. Presented in a matte grey round form factor and size 11, it combines fingertip biomarker sensing with a lightweight design to provide continuous insights into sleep stages, heart rate variability (HRV), skin temperature and overall activity. The ring uses a lithium‑polymer 24 mAh battery and offers up to six days of runtime with USB‑C charging; it works with Android 8–13 and iOS 15–16.
Advantages
The Ultrahuman Ring AIR delivers fingertip‑level accuracy for physiological signals by measuring at the finger where blood flow and arteriole density are higher than the wrist. At approximately 2.4 grams, the ring is extremely lightweight and designed for comfortable round‑the‑clock wear with a hypoallergenic inner lining. It provides detailed sleep staging, a daily sleep score, and a Dynamic Recovery score based on sleep, HRV, skin temperature and stress rhythm to help you plan rest and recovery. Basic features include heart rate monitoring, activity and step tracking, and Bluetooth connectivity for smartphone pairing.
Suitable for
Users who want continuous, non‑invasive sleep tracking and sleep stage analysis
People seeking more precise HRV and recovery metrics than wrist wearables typically provide
Those who prefer a minimal, comfortable wearable for all‑day and overnight use
Individuals who track daily activity, active minutes and heart‑rate‑aware workouts
When it may not be suitable
The Ultrahuman Ring AIR focuses on sleep, recovery and daily activity metrics rather than advanced smartwatch functions such as apps, notifications, or onboard GPS. If you need full smartwatch features (calls, extensive apps, or standalone GPS tracking) this ring may not meet those requirements. Also, size choice is important for accurate readings; an incorrect fit can affect sensor performance.
Key specifications
Form factor: smart ring, round, matte grey, size 11
Weight: approximately 2.4 g
Sensors/metrics: heart rate, heart rate variability (HRV), skin temperature, sleep stage detection, activity and step tracking
Battery: Lithium‑polymer 24 mAh, up to 6 days typical runtime
Charging: USB‑C cable included
Connectivity: Bluetooth (smartphone pairing)
Compatibility: Android 8–13, iOS 15–16
How to use
Wear the Ultrahuman Ring AIR on the finger that provides the best fit and comfort; ensure the ring sits snugly but not too tight to allow accurate sensor contact. Pair the ring with the Ultrahuman mobile app via Bluetooth on a compatible Android or iOS device to enable data sync, view sleep and recovery scores, and configure tracking preferences. Charge the ring using the included USB‑C cable as needed — typical battery life is up to six days depending on usage.
What to consider before purchase
Choose the correct ring size for accurate sensor contact and comfort
Consider whether you need smartwatch features (notifications, apps, GPS) which this device does not prioritize
Verify smartphone compatibility (Android 8–13 or iOS 15–16)
Expect basic activity and heart rate tracking without recurring app fees for standard features
Usage recommendations
For reliable sleep and recovery data, wear the ring consistently day and night, keep the sensor area clean, and sync regularly with the app. Use the Dynamic Recovery score together with sleep trends and HRV insights to plan rest, naps or light recovery sessions and adjust activity intensity based on recovery status.
