Lock My Phone

Uninstalling works like this

 This app needs Device Administrator permission. Otherwise it can't lock your phone.

 What's the purpose of this app?

It's not exactly controversial that YOU NEED A ROUTINE. But it's hard to stick to your schedule when the endless entertainment of the internet is available at your fingertips. Lock my Phone kills that lure so you can concentrate on what's actually important.

While your device is locked you can still access the apps on your lockscreen, take phone calls and call emergency numbers (911 etc.) and emergency contacts (see below). If you unlock it during a lock period it will be locked again right away.
