Product information

Description

The Ultrahuman Ring AIR is a compact smart ring for sleep and fitness monitoring, crafted in a round titanium form factor and available in Size 13. Designed for both men and women, it combines fingertip photoplethysmography (PPG) sensors with a lightweight build to deliver continuous tracking of sleep stages, heart rate, blood oxygen (SpO2) and recovery metrics. The ring pairs with Android and iOS devices via Bluetooth and is powered by a 24 mAh LiPo battery that provides up to 6 days of typical use.

Advantages

The ring uses fingertip PPG sensors to capture biometric signals with greater vascular density than wrist-worn devices, improving accuracy for metrics such as heart rate variability, skin temperature and SpO2. Weighing just 2.4 grams and finished with a hypoallergenic inner lining, the titanium body offers a durable yet comfortable form factor suitable for all-day and night wear. Built-in Bluetooth 5.0 and USB-C charging make connectivity and recharging straightforward.

Suitable for

  • Users seeking detailed sleep-stage analysis and daily sleep scoring
  • People who want continuous heart rate and HRV monitoring for recovery insights
  • Fitness enthusiasts tracking activity, active minutes, calories and workouts
  • Anyone who prefers a discreet, lightweight wearable instead of a wrist device
  • Users who need SpO2 monitoring for wellbeing or altitude/fitness considerations

When it may not be suitable

The ring may not be suitable for users who require on-device displays or advanced smartwatch features such as apps, calls or onboard GPS. It also may not fit those who prefer larger, more visible wearables or who need continuous use beyond the specified battery life without frequent charging.

Key specifications

  • Form factor: round titanium smart ring, Size 13
  • Sensors: infrared PPG for SpO2 and heart-rate metrics, skin temperature sensing
  • Tracked metrics: sleep stages and score, heart rate, heart rate variability (HRV), SpO2, activity (active minutes, calories, distance), workout tracking
  • Connectivity: Bluetooth 5.0
  • Battery: 24 mAh Lithium Polymer (LiPo), up to 6 days typical use
  • Weight: approximately 2.4 grams
  • Charging: USB‑C cable included
  • Water resistance: suitable for everyday use (waterproof rating as specified by manufacturer)

How to use

Wear the Ultrahuman Ring AIR on a finger that fits Size 13 comfortably and sync it with the Ultrahuman app on your Android or iOS device via Bluetooth 5.0. The ring continuously records biometric data; open the app to view sleep-stage breakdowns, daily sleep scores, recovery scores and activity summaries. Charge the ring using the supplied USB‑C cable when the app indicates low battery and follow on-screen guidance for firmware updates and calibration if prompted.

What to consider before purchase

  • Confirm Size 13 is the correct ring size for your finger to ensure accurate readings and comfort
  • Check device compatibility with your smartphone (Android or iOS) and Bluetooth 5.0 support
  • Decide if you prefer a discreet ring form factor over a smartwatch with a display and on-device interactions
  • Consider your expected battery usage patterns and whether up to 6 days between charges meets your needs

Usage recommendations

For best results, wear the ring continuously, including during sleep, and keep it charged regularly. Ensure a snug but comfortable fit to maintain sensor contact with the fingertip. Use the app to monitor trends rather than single measurements, and follow suggested recovery practices (rest, naps, breathwork) provided by the app to improve recovery scores.
