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.

Absolutely loving it! When you are serious about your health, this HART ring definitely helps you in tracking your progress. It is easy, convenient, hassle free and gives you so many parameters to track. The team keeps on bringing new features as well. They really want to bring revolution in preventing healthcare, and this gadget is a tool for this. I would recommend this HART ring for everyone. You can wear it 24*7, the battery lasts long, more than 7 days. Overall, awesome product!

very good to track sleep recovery. it would be better if it could connect with Healthconnect and collect data for workouts, I use Hevy to track my workouts. Google fit collect those data but Hart ring doesn't read those data. even for that matter my home scale doesn't get collected too could have better interface to collect that too

BP readings are unreliable. ⚠️ The ring stops or gives incorrect readings after normal hand washing in ~13°C water and only works again after warming the hand or briefly charging. ❄️🔌 Cold fingers reduce blood flow, which breaks the optical sensor’s signal. 📉 If a device needs perfect conditions, BP values should not be presented as reliable. Okay for wellness trends, not for blood pressure accuracy.
