We recommend to check your app every day, this will ensure the transfer of your heart rhythm data and success of the study.

1. First check if you see the two green marks:

2. If you see a red X, typically the most easy solution is to Force Quit the App and Reopen it again (iOS, Android). In almost all cases, the two green marks will reappear.

Please note that even when you saw a red X, the bracelet has been monitoring and saving your heart rhythm data for up to 20 hours. Once you restart the app, the remaining data on the bracelet will be synched and included for analysis.

3. It is very important to open the app once per day. We may send you a reminder from time to time. Please keep notifications activated for the two months of the study.



Please note we are regularly improving the system and will publish new versions of the apps. It is very important to have the latest version installed on your phone. You can check the following links for the latest version, if you see an <UPDATE> button, please press it and update to the latest version of the app.

After you have updated the app, please press on the <OPEN> button or restart the app from your home screen.
