I'd like an android app, that would lock your phone functions (apps) for a predetermined period of time. Once an user opens the app, he can choose how much time does he want the phone to be locked and apps that he would like to exclude from being locked. So for a set period of time user cannot leave the app, which only displays a clock that show how much time is it left and those few apps that user choose to leave open. Inside an application i would also like to have a place for ads, and a millenial media integration (i already have their account).
I added just a basic sketch.
Please tell me if you can do this project and how much would it cost.
