The app says my device is connected but I don’t see any measurements
There may be two causes:
Your device might not support HRV measurements
Or you didn’t give the required permissions.
To make sure the app has all the necessary permissions:
Open the Health app
Go to the Sharing tab and scroll down
Tap Apps
Find Heartify in the list and tap on it
Make sure all the permissions are enabled.
Return to Heartify and pull down on the dashboard screen. The synchronization icon should appear at the top and your measurements will appear in a minute.
