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 ONE app After activating the ring, please pair with the FITTR ONE app to start using. Not a medical device This ring is not a medical device and should not be used as a substitute for professional medical judgement.
