AppDetox

AppDetox, like Freedom, allows users to ban distracting apps so they can stay focused on the work at hand. AppDetox distinguishes out because it offers customizable options not seen in other distraction-blocking apps. You can, for example, allow yourself to launch an app ten times per day, establish time limitations for applications, ban apps indefinitely, or block apps at specific periods of the day.

You can see how much time you spend on different applications and how many breaks you take throughout the day by looking at your statistics. Users may also set up notifications to inform them of how much time they have remaining on specific applications. AppDetox features no in-app purchases or subscription plans, so it's absolutely free to use.
