Product information

Description

The Ultrahuman Ring AIR is a slim smart ring designed for continuous sleep and fitness monitoring. Housed in a round gold form factor, it combines infrared photoplethysmography (PPG) SpO2 sensing with heart rate and activity tracking to deliver fingertip biomarker data. The ring is lightweight and compact, with a LiPo 24 mAh battery that provides up to 6 days of typical runtime and physical dimensions of approximately 8.1 mm width and 2.45 mm thickness. Compatible with Android 6–13, it offers standard monitoring features without requiring a paid app subscription.

Advantages

Finger-based PPG and SpO2 sensing provide higher blood flow and arteriole density than wrist devices, which improves the accuracy of sleep stage detection, heart rate variability (HRV) and skin temperature trends. At about 2.4 grams and a slim profile, the ring is designed for comfortable day-and-night wear with a hypoallergenic inner lining. The combination of continuous sleep analysis, activity tracking and a multi-day battery life makes it a compact, all-in-one wellness companion.

Suitable for

  • Continuous sleep tracking and sleep stage analysis
  • Daily activity logging (steps, active minutes, calories)
  • Basic cardiovascular and recovery monitoring using HR and HRV
  • Users seeking a low-profile, lightweight wearable for 24/7 use

When it may not be suitable

The Ultrahuman Ring AIR provides detailed trend and recovery metrics but is not a medical diagnostic device and should not replace professional medical monitoring or treatment. Users requiring advanced sports metrics, GPS-based distance tracking, or extensive third-party app integrations may find the ring’s feature set limited compared with dedicated multisport watches.

Key specifications

  • Sensors: infrared PPG for heart rate and SpO2
  • Measured metrics: heart rate, HRV trends, blood oxygen (SpO2), skin temperature trends, sleep stages, steps, active minutes, calories
  • Battery: Lithium Polymer 24 mAh, up to 6 days typical runtime
  • Connectivity: Bluetooth 5.0
  • Form factor: round gold smart ring
  • Physical dimensions: width approx. 8.1 mm, thickness approx. 2.45 mm; weight ~2.4 g
  • Compatibility: Android 6–13

How to use

Wear the ring on a finger that fits comfortably and allows skin contact for sensors. Pair the ring with the companion app over Bluetooth 5.0 on a compatible Android device to enable continuous data syncing. Use the app to view sleep reports, daily activity summaries, recovery scores and sensor trends. Charge the ring with the supplied charger when the battery is low; typical runtime is up to 6 days depending on usage.

What to consider before purchase

  • Ring size — ensure size 8 matches your finger circumference for reliable sensor contact
  • Platform compatibility — compatible with Android 6–13; check iOS support if required
  • Feature scope — provides wellness and recovery insights but is not a medical device
  • Connectivity — requires Bluetooth 5.0 on the host device for pairing and syncing

Usage recommendations

For best results wear the Ultrahuman Ring AIR continuously, including during sleep, and charge it every few days. Keep the sensor area clean and ensure a snug fit to maintain accurate readings. Use sleep and recovery insights over time to identify patterns and adjust routines such as sleep timing, naps or breathwork to support recovery.
