Focus is a free Android app designed to help users quit phone addiction and increase productivity. The app offers the option to disable or lock your phone for a specified time period. Users can choose between the easy mode that allows for breaks or the no-break mode that requires complete concentration.

One of the app's unique features is that it requires MIUI users to grant PopUp and Auto Start permissions. This ensures that the app works effectively and without any interruptions. Focus is an excellent tool for anyone struggling with phone addiction or procrastination, and who wants to improve their productivity levels.
