How tight should a ring be?

Secure but not restrictive. It should slide smoothly over your knuckle with a bit of resistance, neither too tight nor too loose. Test the fit by making a fist. If you see a gap between your finger and the ring, you may try a smaller size.

What finger or hand does a ring go on?

For the best accuracy, it is recommended to wear it on the index finger of your nondominant hand. If you prefer another finger, the middle or ring fingers are preferable.

Stuck between sizes?

We recommend choosing the smaller size as it provides a snug fit that will enhance accuracy.

How does LYNX track sleep?

A green light sensor in LYNX monitors heart rate and identifies sleep states across four zones, while an accelerometer detects disturbances in sleep quality.

What do LYNX’s infrared sensors do?

The IR sensors measure oxygen saturation levels in your blood; they indicate how well your circulatory system is working.
