Product information

Description

The Ultrahuman Ring AIR is a compact smart ring in a round titanium form factor (Size 5) designed for continuous sleep and fitness monitoring. Using infrared photoplethysmography (PPG) at the fingertip, it measures blood oxygen (SpO2), heart-rate related metrics and skin temperature, and pairs via Bluetooth with USB‑C charging for up to six days of battery life on its 24 mAh LiPo cell. The narrow 8.1 mm profile and lightweight titanium construction make it suitable for all-day and night wear without significant discomfort.

Advantages

The ring provides fingertip-level biomarker accuracy, benefiting from higher blood flow and arteriole density compared with wrist devices to deliver precise readings for sleep stages, heart rate variability (HRV), and skin temperature. At about 2.4 grams and a slim 8.1 mm profile, the titanium design combines low weight, durability and a hypoallergenic inner surface for comfortable continuous wear. Built-in waterproofing, Bluetooth 5.0 connectivity and multi-day battery life support everyday use with straightforward charging via USB‑C.

Suitable for

  • People tracking sleep quality and detailed sleep stages (including REM and deep sleep)
  • Those monitoring recovery and readiness using HRV, skin temperature and sleep-based recovery scores
  • Users who want a low-profile, lightweight alternative to wrist wearables for 24/7 monitoring
  • Fitness-minded individuals who want basic activity metrics (active minutes, calories, distance) combined with sleep and recovery data

When it may not be suitable

The Ultrahuman Ring AIR provides clinical-grade-inspired metrics for daily wellness but is not a medical device and should not replace professional medical diagnostics or treatment. Users who need continuous, hospital-grade monitoring or specific medical-grade sensors should consider dedicated medical equipment.

Key specifications

  • Form factor: round titanium ring, narrow 8.1 mm profile, Size 5
  • Sensors: infrared PPG for SpO2 and heart-rate metrics, skin temperature sensor
  • Connectivity: Bluetooth 5.0; USB‑C for charging
  • Battery: 24 mAh LiPo cell; up to 6 days typical runtime
  • Weight: approximately 2.4 grams
  • Water resistance: suitable for everyday water exposure (waterproof)

How to use

Wear the Ultrahuman Ring AIR on a finger that fits comfortably and allows skin contact with the inner sensors. Pair the ring with the companion app via Bluetooth, follow the in-app setup to calibrate personal profiles and enable continuous monitoring. Charge the ring using the included USB‑C cable when the app indicates low battery; typical runtime is up to six days depending on usage. Use the app to review sleep stages, Recovery Score, HRV trends, SpO2 readings and basic activity metrics.

What to consider before purchase

  • Size: ensure Size 5 is an appropriate fit for your finger to maintain accurate sensor contact
  • Purpose: the ring is intended for wellness, sleep and fitness insights, not for medical diagnosis
  • Compatibility: requires a smartphone with Bluetooth and the Ultrahuman companion app

Usage recommendations

For best results wear the ring continuously, including overnight; keep the inner surface clean and ensure a correct fit for accurate SpO2 and HRV readings. Use the Recovery Score and sleep insights to guide rest, naps and breathwork rather than to self-diagnose health conditions.
