In my opinion the Health connect feature is in an early stage of development and needs to be improved to be really useful. I do my exercises and monitor them with Samsung Galaxy watch. If I turn on Health connect, I will end up having all my training activities duplicated. Everything recorded in freeletics come to Samsung Health so in Samsung Health I have it twice. Vice versa my training recorded in Freeletics by the Coach gets duplicated with a recorded session in Samsung Health. In my opinion the Freeletics app should somehow identify records coming from Samsung Health and link them with the corresponding training in Freeletics.
Yeah, this is a huge flaw. The app needs to identify duplicate entries and not add them all up.
