We do not currently sync daily health metrics from platforms such as Garmin Connect, Polar Flow and other activity trackers. However, our iOS app does connect with Apple Health and sync Daily Vitals that way. If you do not have an iPhone or don't use Apple Health, Daily Vital metrics will need to be entered manually through our iOS and Android apps.

In addition to our Apple Health sync, we also sync Resting Heart Rate and HRV from the following apps:
