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.

READ BEFORE PURCHASING THE RING. AS YOU'LL NOT BE A CUSTOMER BUT A SILENT DEVELOPER/ BETA TESTER I’ve been using the Hart Ring 2 for 6 months. While the ring is accurate when it works, the data is inconsistent. Some days all metrics are tracked, but on others, random health metrics fail to record despite wearing it all day. It's better to wait for a better version or go for another smart ring as INR 18,000 for this piece of tech which doesn't work 60% of the time is just not worth it.

The features are really good. I had some connectivity issues earlier, but the technical team assisted me promptly and kept taking my feedback to improve things. I’m especially glad that the Nutriview feature has been added—it’s amazing, very user-friendly, and I absolutely love it! Overall, I’m very happy with both the ring and the app now.

Feature Request: I want to see the battery statistics, not just the last charged and battery percentage. It would be great if you can add how the battery is draining and its longevity. Another request is for me to unpair the ring from my other phone, as others have access to that.
