Product information

Description

Ultrahuman Ring Air in Aster Air Black is a slim smart ring designed for continuous activity, sleep and health tracking. Sized 12 with an 8.1 mm profile, it uses an infrared PPG sensor to monitor blood oxygen (SpO2), heart metrics and skin temperature, and offers up to six days of battery life with USB‑C charging in a compact round form factor.

Advantages

The ring provides fingertip-level biometric accuracy for sleep, recovery and vital sign monitoring, benefiting from higher blood flow and arteriole density compared with wrist wearables. At about 2.4 grams and 8.1 mm wide, its featherlight, hypoallergenic inner lining supports all-day and night wear without noticeable discomfort. Built-in waterproofing, Bluetooth 5.0 connectivity and a 24 mAh LiPo battery combine for reliable everyday use.

Suitable for

  • People who want precise sleep stage and sleep quality monitoring
  • Users tracking recovery metrics such as HRV and skin temperature
  • Those who prefer a minimal, lightweight wearable instead of a smartwatch
  • Active users who need continuous activity and workout tracking

When it may not be suitable

The ring may be unsuitable if you need advanced smartwatch features such as apps, notifications, a touchscreen, or integrated GPS. It also might not fit users who require larger ring sizes than size 12 or who prefer a wrist-based device for on-the-go interaction.

Key specifications

  • Form factor: round smart ring, slim profile (8.1 mm width)
  • Weight: approximately 2.4 g
  • Sensors: infrared photoplethysmography (PPG) for SpO2, heart rate and related metrics; skin temperature monitoring
  • Connectivity: Bluetooth 5.0
  • Battery: 24 mAh LiPo, up to 6 days runtime
  • Charging: USB-C
  • Water resistance: designed to be waterproof (suitable for daily use)

How to use

Wear the Ultrahuman Ring Air on a finger where it fits comfortably and snugly to ensure consistent sensor contact. Charge the ring using the included USB‑C cable and pair it with the Ultrahuman app via Bluetooth 5.0 to set up continuous tracking. Use the app to view sleep stages, daily sleep score, recovery score and activity summaries and to access personalized recovery suggestions and breathing or nap techniques.

What to consider before purchase

  • Confirm ring size (this listing is size 12) to ensure proper fit and accurate readings
  • Decide whether fingertip-based tracking suits your needs versus a wrist wearable
  • Check that USB‑C charging and up to 6 days battery life meet your usage patterns

Usage recommendations

For best results wear the ring continuously, especially during sleep and rest periods, keep the sensor area clean and dry, and sync regularly with the app to receive up-to-date recovery and sleep insights.
