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. It is not designed or intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of any condition or disease. Please consult your healthcare professional prior to making any decisions related to your health.
