Product information

Description

The Ultrahuman Ring AIR is a smart ring activity tracker in black designed for continuous sleep and fitness monitoring. Its compact round form and 8.1 mm width house infrared photoplethysmography (PPG) blood oxygen sensing (SpO2), heart-rate related measurements and a 24 mAh LiPo battery charged via USB‑C that provides up to 6 days of typical use. The ring is available in Size 13 and delivers on-device sensing without mandatory app fees, making it suitable for daily activity tracking, sleep analysis and fitness monitoring.

Advantages

The ring’s fingertip-based PPG sensor takes advantage of higher blood flow at the finger to capture physiological signals with improved contact compared with many wrist devices. Its lightweight design and narrow 8.1 mm profile support all‑day and overnight wear. USB‑C charging and a 24 mAh LiPo battery rated for up to 6 days simplify charging routines, while integrated SpO2 sensing and core activity metrics cover key health and recovery insights.

Suitable for

  • Daily activity monitoring and step tracking
  • Sleep stage analysis and nightly sleep scoring
  • Fitness tracking including active minutes and workout monitoring
  • Recovery and readiness monitoring using heart-rate related metrics and SpO2

Key specifications

  • Form factor: round smart ring, black color
  • Size: 13
  • Sensor type: infrared photoplethysmography (PPG) with SpO2 capability
  • Battery: Lithium Polymer (LiPo), 24 mAh
  • Typical battery life: up to 6 days
  • Charging: USB‑C
  • Ring width: 8.1 mm

How to use

Wear the Ultrahuman Ring AIR on the finger size indicated (Size 13) so the sensor sits flush against the skin for reliable readings. Charge the device using a USB‑C cable before first use and periodically as needed; the 24 mAh battery typically lasts up to 6 days depending on usage and settings. Use the ring continuously to capture overnight sleep data and daytime activity; ensure good skin contact during exercise and rest for accurate PPG and SpO2 measurements. Follow the manufacturer’s setup steps in the accompanying materials to enable pairing and data syncing.

Usage recommendations

For optimal results, wear the ring consistently day and night, maintain a clean sensor surface, and charge when battery levels are low to avoid gaps in tracking. Remove the ring for activities that may expose it to strong impacts or harsh chemicals. Note that accuracy can depend on fit and placement; ensure a snug, comfortable fit on the chosen finger.
