## Summary description

Ultrahuman Ring AIR is a smart ring activity tracker for men and women that monitors sleep and fitness. It features a round grey form factor, supports Android (8.0–13.0) and iOS (15–16), and includes a USB‑C to USB‑C cable. Battery is a 24 mAh LiPo unit providing up to 6 days of use. Practical for continuous heart rate and sleep monitoring and daily activity tracking.

## Long description

The Ultrahuman Ring AIR is a lightweight smart ring for men and women that monitors sleep, recovery and daily activity. In a matte grey round form factor and size 9, the ring records fingertip biometrics such as heart rate variability, skin temperature and sleep stages and syncs with Android and iOS devices via Bluetooth. With a 24 mAh LiPo battery the device delivers up to 6 days of typical use and includes a USB‑C to USB‑C charging cable.
Advantages
The ring provides fingertip-level accuracy by measuring where blood flow and arteriole density are higher than on the wrist, which improves the precision of heart rate, HRV and skin temperature measurements. Weighing approximately 2.4 grams and featuring a hypoallergenic smooth inner lining, the design prioritizes comfort for continuous, day-and-night wear. The device combines sleep stage analysis, a daily sleep score and a Dynamic Recovery score to give an integrated view of rest and recuperation.
Suitable for
Users who want detailed sleep-stage tracking and a daily sleep score
People seeking continuous heart rate and HRV monitoring for recovery insights
Those who prefer a discreet, lightweight wearable instead of a wrist device
Fitness enthusiasts who track activity, active minutes and steps
When it may not be suitable
The Ultrahuman Ring AIR is compact and focused on biometric and sleep analytics; it does not replace multi-function smartwatches if you need on-screen notifications, apps, GPS navigation or extensive third-party integrations. Users who require heavy-duty battery life beyond the stated up-to-6-day range or who need an always-on display may find a wrist device more appropriate.
Key specifications
Form factor: round matte grey smart ring, size 9
Sensors: fingertip photoplethysmography for heart rate and HRV, skin temperature sensor, motion sensor for sleep and activity detection
Battery: 24 mAh Lithium Polymer (LiPo), up to 6 days typical use
Connectivity: Bluetooth; charges via included USB‑C to USB‑C cable
Compatibility: Android 8.0–13.0 and iOS 15–16
Weight and comfort: approximately 2.4 g, hypoallergenic inner lining
How to use
Fit the ring on your finger (size 9) so it sits comfortably and maintains contact with the fingertip. Install the Ultrahuman companion app on a compatible Android or iOS device, enable Bluetooth and follow the in-app pairing instructions. Wear the ring continuously to capture sleep stages, HRV, skin temperature and activity; charge it using the supplied USB‑C cable when the app notifies you of low battery.
What to consider before purchase
Ensure size 9 fits your finger for consistent sensor contact
Confirm your smartphone meets compatibility requirements (Android 8.0–13.0 or iOS 15–16)
Consider whether a discreet ring tracker meets your needs versus a smartwatch with notifications or built-in GPS
Expect typical battery life up to 6 days depending on usage and sync frequency
Usage recommendations
For reliable readings, wear the ring continuously day and night, keep the inner surface clean, and follow the app’s guidance for charging and calibration. Use the sleep score and Dynamic Recovery insights together to plan rest, short naps or breathwork sessions to improve recovery.
