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. If you unlock it during a lock period it will be locked again right away.

3 main Features:
* Recurring lock periods, for example to lock your phone every evening during the week after 10 pm.
* One time lock periods for when you just want to concentrate for 45 minutes while studying.
* Geocheck-Feature: Only lock your device if you are in a certain area. Helpful so your phone isn't locked while you're out with friends.

Difference between free and premium version: You can only have one lock period at the same time on the free version. You can have unlimited lock periods (of each type) in the premium version. There are no ads in either version.
