Product information

Description

Ultrahuman Ring AIR is a compact smart ring for men and women designed to monitor sleep and fitness. The ring combines fingertip PPG SpO2 sensing, heart-rate tracking and lightweight comfort to provide continuous insights into sleep stages, recovery and daily activity. It charges via USB‑C, has a narrow 8.1 mm profile and delivers up to six days of battery life for extended wear without frequent recharging.

Advantages

The Ultrahuman Ring AIR uses fingertip infrared PPG sensors to capture blood-oxygen levels (SpO2), heart rate and skin temperature with greater signal quality than typical wrist devices, supporting more accurate sleep and recovery analysis. At approximately 2.4 grams and with a smooth hypoallergenic inner lining, the ring is designed for all-day and overnight comfort. Standard features do not require an app subscription, and the USB‑C charging and multi-day battery life make it convenient for continuous monitoring.

Suitable for

  • People who want detailed sleep stage and recovery insights
  • Fitness-conscious users tracking heart rate, active minutes and calories
  • Anyone preferring a low-profile, lightweight wearable
  • Users who need several days of battery life between charges

When it may not be suitable

The Ultrahuman Ring AIR is not intended to replace medical-grade devices; it provides wellness and lifestyle insights rather than diagnostic medical results. Users who need continuous on-wrist displays or advanced smartwatch apps and notifications may find a smart ring’s limited display capabilities restrictive.

Key specifications

  • Form factor: round smart ring, 8.1 mm width
  • Sensors: infrared PPG for SpO2 and heart-rate monitoring, skin temperature sensing
  • Tracking: sleep stages, recovery score (HRV-based insights), active minutes, calories burned, distance
  • Connectivity: Bluetooth 5.0
  • Charging: USB‑C
  • Battery: Lithium Polymer, 24 mAh; typical runtime up to 6 days
  • Water resistance: suitable for daily use and exposure to water
  • Weight: approximately 2.4 g

How to use

Wear the ring on a finger that fits comfortably and allows the sensor to maintain contact with the skin. Charge the device via the USB‑C cable before first use and pair it with the companion app over Bluetooth 5.0 to enable data sync and personalized insights. Wear the ring continuously, including overnight, to collect sleep, recovery and activity metrics. Review daily scores and trends in the app to understand sleep quality, recovery status and activity patterns.

What to consider before purchase

  • Ring size and fit — ensure Size 8 matches your finger measurements
  • Intended use — wellness and fitness insights, not medical diagnosis
  • Compatibility — requires a smartphone with Bluetooth for app pairing
  • Charging routine — USB‑C charger and up to 6 days runtime between charges

Usage recommendations

For best results, wear the Ultrahuman Ring AIR continuously, including during sleep, keep the sensor area clean, and charge it regularly to maintain uninterrupted tracking. Use the app to view recovery scores and adapt rest, naps or breathwork exercises based on the ring’s insights.
