Free Version: Extremely Limited, Premium: Not worth $4.99
Free version can only handle 3 habits meaning if you would like to keep track of anything else, you have to pay $4.99. Mind you, Coach.me, which is available for iOS does nearly everything this app does except it cannot be synced between all devices because it lacks a OS X app, which may end up being a huge drawback for some people. If you don’t mind paying the $4.99 this app is perfect for you, it has great funcitonality and design. That being said, so do most app dedicated to this sort of thing. If you don’t really care about the app being synced between devices and having it on OS X, look elsewhere. There are plenty of great and free alternatives to this app.
