Product information

Description

The Ultrahuman Ring AIR is a compact smart ring designed for sleep and fitness monitoring. In a matte grey round form (Size 5) it combines fingertip photoplethysmography (PPG) sensors for SpO2 and continuous heart-rate measurement with activity tracking and multi‑day battery life. The device collects biometric data to provide sleep analysis, recovery scores and daily activity insights without requiring a paid basic app subscription.

Advantages

The ring’s fingertip PPG sensors offer higher blood flow and arteriole density than wrist devices, which improves the precision of metrics such as heart rate variability (HRV), skin temperature and blood oxygen (SpO2). At approximately 2.4 g and with a hypoallergenic inner lining, the Ultrahuman Ring AIR is lightweight and comfortable for 24/7 wear. Built‑in Bluetooth 5.0 and a 24 mAh LiPo battery deliver up to six days of typical use, enabling continuous tracking of sleep stages, activity and recovery.

Suitable for

  • People who want detailed sleep staging and everyday sleep scores
  • Users seeking continuous heart rate and SpO2 monitoring from a fingertip sensor
  • Individuals tracking recovery metrics such as HRV, skin temperature and sleep quality
  • Anyone who prefers a discreet, lightweight wearable for day and night use

When it may not be suitable

The ring may not be suitable for users who need smartwatch-style features such as on-device apps, notifications, or a large display for interaction. It is also not ideal for people who require medical-grade oximetry; the SpO2 measurements are intended for wellness and fitness insights rather than clinical diagnostics.

Key specifications

  • Form factor: round smart ring, matte grey, Size 5
  • Sensors: infrared PPG for SpO2 and continuous heart-rate monitoring; HRV and skin temperature estimation
  • Tracked metrics: heart rate, HRV, SpO2, sleep stages, activity (steps, distance, active minutes), calories burned
  • Connectivity: Bluetooth 5.0
  • Battery: 24 mAh LiPo, up to 6 days typical use
  • Weight: ~2.4 grams; hypoallergenic inner lining for comfort

How to use

Wear the ring on a finger that fits Size 5 snugly but comfortably. Pair the ring with a compatible Android device via Bluetooth 5.0 and follow the app setup to allow biometric data recording. Wear the ring continuously to collect sleep, activity and recovery metrics; recharge the ring according to usage patterns to maintain up to six days of battery life. Use the companion app to view sleep staging, Recovery Score and daily activity summaries.

What to consider before purchase

  • Check that Size 5 is the correct ring size for your finger to ensure accurate sensor contact
  • Confirm your phone’s Android version is compatible with the Ultrahuman companion app
  • Decide whether wellness-grade SpO2 and HRV insights meet your needs versus clinical measurements

Usage recommendations

For best results, wear the Ultrahuman Ring AIR continuously, especially during sleep and recovery periods. Keep the sensor area clean and ensure a proper fit to maximise measurement accuracy. Use the Recovery Score and sleep reports in the companion app to guide rest, naps and breathwork practices for improved recovery.
