Which finger should I wear my ring on, and how, for the best measurements?

How well your Kuno Ring 2 measures depends largely on how you wear it. With the right finger and a good fit, you get the best results from your ring.

Which finger to choose

front_hand Index finger of your non-dominant hand. This is the recommended finger. If you are right-handed, that is your left index finger.
swap_horiz Middle or ring finger. If you prefer another finger, your middle and ring fingers work as well.
do_not_disturb_on Avoid narrow fingers. Don't choose a finger whose base is narrower than the knuckle. The ring won't sit securely there.

How to wear the ring

Sensor towards your palm
The sensor on the inside of your ring should be on the palm side of your finger.
Slide it to the base
Wear the ring at the base of your finger. It should fit securely there and still feel comfortable.
Check the fit
If the ring is too loose or too tight, read what to do when your ring doesn't fit or gets stuck.

Good to know

fingerprint A good fit gives better measurements. Measurements only work when the ring fits well around your finger. If a measurement fails, wear the ring a bit tighter, keep your hand still and try again. Also read why a measurement fails.
sensors The app keeps track of whether you wear the ring. If you don't, the app skips measurements. Read how the app knows whether you are wearing your ring.
schedule Your finger size changes. Finger size can vary depending on the time of day, so the ring may sometimes be hard to take off.
