About this product
Powerful Health Tracking in a Lightweight Ring
The Ultrahuman Ring AIR in Aster Black is a titanium smart ring that quietly tracks your sleep, activity, stress, heart health and recovery, day and night. Weighing just 2.4 to 3.6 grams depending on size, it is comfortable enough to forget you are wearing it.
All your insights are available in the Ultrahuman app with no subscription required, and the battery lasts up to 6 days between charges.
Better Sleep Starts With Better Data
Ring AIR breaks your night into REM, deep and light sleep plus time awake, and keeps track of your sleep debt. Combined with heart rate, heart rate variability and skin temperature, it helps you understand how well you are recovering and when to push or rest.
