Core sensors include infrared PPG for blood oxygen (SpO2) and heart-rate monitoring. Battery: 24 mAh LiPo with up to 6 days runtime and USB‑C charging.

## Long description

The Ultrahuman Ring AIR is a compact smart ring designed for sleep and fitness monitoring. In a round black form with an 8.1 mm band width and size 9, it combines fingertip PPG sensors for heart rate and SpO2 with a lightweight, comfortable design. The ring supports continuous sleep analysis, activity tracking and heart-rate-aware workouts, and provides multi-day battery life with USB‑C charging for everyday use.
Advantages
The ring uses infrared PPG sensors located at the finger for higher blood flow detection, which improves accuracy for metrics such as heart rate variability (HRV) and blood oxygen (SpO2) compared with typical wrist devices. At approximately 2.4 grams and with a hypoallergenic inner surface, the Ultrahuman Ring AIR is comfortable to wear day and night while remaining discreet. Built-in waterproofing, Bluetooth 5.0 connectivity and up to six days of runtime from a 24 mAh LiPo battery make it practical for continuous monitoring without frequent charging.
Suitable for
Overnight sleep monitoring and analysis
Daily activity and workout tracking with heart-rate awareness
Tracking recovery and physiological trends such as HRV and skin temperature
Users who prefer a low-profile wearable instead of a wrist device
When it may not be suitable
The Ultrahuman Ring AIR is optimized for continuous, comfortable wear and fingertip-based biometrics, but it may not be suitable if you require more extensive smart features such as on-screen notifications, built-in GPS, or a large display. Users who need medical-grade diagnostics should not rely solely on consumer wearable readings for clinical decisions.
Key specifications
Form factor: round smart ring, width 8.1 mm, size 9
Weight: approximately 2.4 g
Sensors: infrared PPG for heart rate and blood oxygen (SpO2); skin temperature sensing
Connectivity: Bluetooth 5.0
Battery: 24 mAh LiPo, up to 6 days typical runtime; USB‑C charging
Water resistance: designed for everyday use (waterproof)
How to use
Put the ring on a finger that fits snugly—typically the index or middle finger—so sensors maintain good contact with the skin. Pair the ring with the Ultrahuman app over Bluetooth 5.0 to sync data and view sleep stages, recovery scores, HRV and activity metrics. Charge the ring via the USB‑C charger when the battery is low; typical runtime is up to six days depending on usage. Wear continuously, including overnight, for the most reliable sleep and recovery insights.
What to consider before purchase
Choose the correct ring size to ensure sensor contact and comfort
Assess whether fingertip-based tracking and the provided metrics meet your monitoring needs
Confirm compatibility with your smartphone and that Bluetooth 5.0 is supported
If clinical accuracy is required, consult a healthcare professional rather than relying solely on the ring
Usage recommendations
For best results wear the Ultrahuman Ring AIR continuously, ensure a snug but comfortable fit, keep the sensor area clean, and sync regularly with the Ultrahuman app to track sleep, recovery and activity trends over time.
