How to correctly wear your FITTR HART Ring
For best performance and accurate readings, we recommend wearing your HART Ring on the index finger of your non-dominant hand. Middle and ring fingers work too, if that’s what you prefer. Just make sure that the ring fits securely and comfortably around the base of your finger - not too loose, not too tight.
Note: the ring’s sensor should face the palm side of your finger and not the top.
How to use the FITTR Hart app
After activating the ring, please pair with the HART app to start using.
