## Long description

Ultrahuman Ring Air Size 12 in Black is a compact smart ring activity tracker with an 8.1 mm band width designed for continuous daily and nocturnal monitoring. The ring uses infrared photoplethysmography (PPG) to measure blood oxygen (SpO2) and other physiological signals, and it includes motion sensors for activity tracking. A 24 mAh lithium‑polymer battery provides up to 6 days of operation between USB‑C charges. The device collects sleep and recovery metrics, cardio data and daily activity measures to support ongoing health awareness and lifestyle adjustments.
Advantages
The Ultrahuman Ring Air delivers passive, 24/7 monitoring without bulky hardware, offering multi‑day battery life and convenient USB‑C charging. Its infrared PPG sensor enables continuous SpO2 monitoring while motion sensors and algorithms track steps, distance, calories and VO2 Max. Nightly analysis provides sleep staging, sleep score and recovery insights such as HRV trends and skin temperature changes. The ring’s compact design and size 12 fit make it suitable for continuous wear and unobtrusive monitoring of daily physiology.

How to use
Place the Ultrahuman Ring Air on the finger that corresponds to size 12 so the sensors sit comfortably against the skin. Charge the ring using the included USB‑C cable until fully charged before first use. Install the Ultrahuman companion app on a compatible smartphone, follow pairing instructions and allow required sensor and background permissions. Wear the ring continuously for best results: it collects activity data during the day and physiological and sleep data at night. Sync the ring with the app regularly to view trends, nightly reports and recovery scores.
Usage recommendations
For accurate readings, ensure the ring fits snugly but comfortably and sits flat on the finger; avoid loose wear. Charge the device at convenient intervals to maintain continuous monitoring—typical full charge intervals are every few days depending on usage. Use the app’s sleep and recovery insights to adjust bedtime routines, daytime light exposure and caffeine timing. If you rely on medical‑grade interpretation for an abnormal heart rhythm or SpO2 reading, consult a healthcare professional.
