Ultrahuman Ring Air

Up for sale is my Ultrahuman Ring AIR in Matte Black. This is one of the best smart rings on the market and a great alternative to a bulky smartwatch.

What's included:
Ultrahuman Ring AIR (Matte Black) Size 9
Charging dock & cables
Ring protectors

Key features:
* Ultra-slim profile at only 2.4mm thick and weighing as little as 2.4 grams — barely noticeable on your finger
* Tracks heart rate, HRV, blood oxygen (SpO2), body temperature, and movement via a 6-axis motion sensor
* Detailed sleep tracking with sleep stages, recovery and movement index, step counting, and workout mode
* No mandatory monthly subscription — access all your core health data for free
* Compatible with both iOS and Android via the Ultrahuman app

A great pick if you want comprehensive health tracking without the screen. Feel free to message with any questions!
