Could be a great app except that like another user said, it does not sync between devices when the description claims that it can. That's a big letdown for me because when used any other of my devices, and when I switched phones, I couldn't sync the app up with my data or any habits I've been tracking, even though I have the premium account. When attempting to sync It always says that there is no internet connection, but there always is. So I can't give it a full 5/5 rating, otherwise I might.
