Size and details
Finding Your Perfect Fit
To capture the most accurate data, we recommend wearing your Usay Ring 1 on your index finger. If you prefer another finger, simply ensure a comfortable fit at the base of that finger — snug enough to stay in place, but loose enough to twist with light resistance.
Note: Finger size can vary throughout the day (temperature, activity, hydration). If the ring ever feels tight, apply a little mild soap and cold water, then gently twist it off — avoid pulling forcefully.
Sensor Orientation
The sensors (located near the charging contacts on the inner side of the ring) must face the palm side of your finger — the inner, fleshy side. This ensures accurate body energy and stress readings.
