Heart Rate is not visible in Fitness / Apple Health (Troubleshooting)

If your Heart Rate is not visible in Fitness / Apple Health, even though you have Live Sync turned on, you may see something like this.

Usually this may have happened for one of the following reasons:

• Strong for Apple Watch was closed for some reason during a workout (e.g. low battery)
• Your Apple Watch was not able to record enough readings accurately during the workout. Try to make sure that the fit on your Apple Watch is as tight as possible.
• Strong for Apple Watch may have crashed during your workout. Even if you restart Strong, we are not able to 'reconnect' the separate workout sessions and this may result in missing data such as in the screenshot above. Please check the article here for additional troubleshooting tips. 

If you have incomplete Heart Rate data, unfortunately this may result in inaccurate values for calories burned.
