6 Euro down the drain. ‚Sync with Health‘ is an absolute lie. There are no settings in this app, where you could turn the sync on. The app suggests to get the fitness app linked with this one (Stark Fitness). What I did. This one didn‘t have a ‚Sync with Health‘ either. Maybe if you go premium on the Stark Fitness app. Maybe. Not worth the Risk. Shady business, waste of money for me. If you just want to see the excersises, buy a book or a DVD. So, you at least know what you get for your money. Installed it ... deleted it a minute later. Beware! False advertisment!
