This to me reads that you have a serious self control issue. If you need to use an app to limit your use of another app, you've fucked up. Learn and practice some self control. You don't need a timer, you don't need to remove the app or get yourself banned, just stop using it. This is like needing to have your parents tell you to do your homework or something. You are in control of your life. You will feel much more empowered if you do it yourself.
