Gymrun app

This is a great app for working out that has IOS, Samsung, and WearOS options for watches as well as phone apps. It already does sync to Google Fit and Fitbit but those just show that you did a workout. The app itself tracks what exercises, times, sets, etc and it would be great to see that info show up in Exist.
Not possible as no API.
