I gave it a try, it was pretty cute to have a rocket blocking every app you open and a timer to show the remaining time. But as a suggestion, can you put in exclusion functionality to certain apps? I tried opening the dictionary app and had to interupt the rocket, I was really sad when it says I failed ;(
Cancelled an time task (while just orientating myself to the program) and it said, "You Failed!" and my phone went crazy with flashing screens like a virus. I turned my phone off, restarted and then uninstalled the program.
