Wearing Guide
Choose Your Finger
The RingConn Smart Ring fits all fingers and can be worn on either hand. For optimal accuracy, we recommend wearing it on your index finger. You can also try it on your middle finger for comfort.
Confirm Ring Orientation
When wearing the ring, position the ring tracker (sensor side) against the pad of your index or middle finger. This ensures the ring is oriented correctly for accurate sizing and optimal sensor contact.
Wear for 24 Hours
Your fingers naturally expand and shrink throughout the day due to temperature, activity, and sleep. To find your most accurate fit, wear the ring sizer for at least 24 hours, including during sleep.
A well-fitting ring should feel comfortable and stay securely in place without rotating during your daily activities.
