It's a memory hog, slow, and the UI is aweful (for example, once you enter your food for a meal, there's no button to get back to "My Day", so you have to use the phones back button. Since the app is so sluggish, I end up accidentally exiting instead of going "home" - just a stupid user experience). The sync with Google fit doesnt work. Edit: Still slow & with the latest update rollover points no longer work and it wont correctly add up daily food points. They found a way to make it worse.
