Can you add more integrations to other services?
RepCount does support syncing workouts to Apple Health (on iOS) and Google Fit (on Android) which enables third parties to sync RepCount workouts if supported. You can enable sync in settings.
Integrations takes a lot of time for development and maintenance. The RepCount team is a very small team and because of this, it is hard to support third party integrations. Some of the bigger apps like Strava, MyFitnessPal and FitBit do not support workout sync via Apple Health or Google Fit and because of this you are unfortunately not able to sync your workouts to these services.
