App Blocker: Curbox Detox

App Blocker: Curbox Detox is an Android application from Nethical that combines two functions: blocking access to selected software and content, and recording how long the device is used. Blocking covers installed applications, websites, and the short-form video feeds inside other apps, specifically reels and shorts, which means the target is not only whole programs but particular sections within them.

The screen time tracker side keeps a record of usage, giving a basis for deciding what to restrict. Together, the two halves are aimed at people trying to reduce time spent on a phone rather than administrators managing someone else's device, though the facts recorded here do not describe how rules are configured or whether they can be locked against changes.

Distribution is under the GNU General Public License, version 3 or later, so the source is available to read and modify. The listing names Android as the only platform, so there is no desktop counterpart to extend the same rules to a computer, and blocking applies to the handset it is installed on.
