The app automatically displays a list with all applications installed on your phone and lets you block whichever you want. You simply need to tap on the app that you would like to block and set a time from 10 minutes to 12 hours. Once you set the timer, ClearLock won’t let you access block applications so you wouldn’t get distracted from work.
 
The app also comes with the option to schedule lock sessions and pick apps that would be included in these sessions. ClearLock also has a home screen widget for accessing the app faster and enabling lock sessions, but these two features are only available in the pro version.
