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.

Hi Team, Building activity report fails after every workout. Please fix the issue.

This is a solid app with good potential, but it restricts too much of the data. I’d like to see stronger integration with Apple Health so I can share and centralize more metrics. Not every module is useful for every user, and the option to hide or remove sections like “Nutrition” would make the experience cleaner. If that module pulled macros and calories directly from Apple Health, it would be valuable, but I already use a dedicated app for nutrition and do not want to enter the same data twice. I chose this ring to gain deeper insights, but much of that data is trapped in the app, while at the same time the app is not incorporating information that is already available. Strengthening Apple Health integration would solve both issues and make the ring much more valuable.

I’d like to be able to add an activity after I’ve done it. I don’t always have my phone beside me when I’m starting an activity like playing pickleball or doing a cardio class. If I could add the activity after and see my calories and heart rate, it would be helpful. I’d also like to see my activities listed like walking- 23 min, cardio class 45 min etc.
