AppBlock - Stay Focussed is an excellent app for those people who want to improve their productivity and avoid being distracted continuously with their phone or device.

With AppBlock you can block apps such as Facebook, Twitter, Instagram and even games to improve your concentration. With this app you can choose how long you stop having access to those apps which are distracting you.

In addition to being able to prevent you from accessing blocked apps, AppBlock also mutes all notifications from those apps, removing this additional distraction. How do you prevent temptation from leading you to unlock apps that you had previously blocked? Very simple: select AppBlock from the blocked applications, so you won't be able to open its access until the time you selected elapses.

The latest version of AppBlock incorporates many new features, including a tool to create different profiles that block different apps depending on what you have previously chosen.
