You can wear your ring on any finger. However, the index, middle,and ring fingers
typically provide the best fit and sensor performance.

The ideal fit is snug, secure, and comfortable. When you make a fist, the ring should not rotate easily,
and there should be no visible gaps between the ring and your finger.
