A very good idea, but too unreliable, blocks apps when it shouldn't and doesn't limit them when it should. If an update could fix those problems I might continue using it.
[updated] The best part of this app is time limits for a group of apps. I've been waiting for this feature from any app vendor and here it is, finally. All "Games" can be limited while leaving other apps (say, Camera or a music player) unrestricted. However, the actual blocking is VERY buggy. One app group has an hour allocated every day, but all its apps are already blocked first thing in the morning. It counts the time that an app is in the background. It often puts up a screen that says Facebook is being blocked, even though Facebook isn't running (even in the background) -- and it claims that I've opened Facebook 70+ times even though I haven't opened it once. And once you've put an app in a group, it no longer reports time spent in the app. It just says how many times you've opened it. So: promising start, but still rough and buggy.
Does not work App does not count active minutes (all permissions granted) and therefore does not block app when time limit reached.
