A free app for Android, by JoLo Software.
TimeLimit.io is an application to manage time limits for apps. You can create and manage profiles, and set rules to limit the usage duration of an app. This is the most flexible solution to limit the time of apps.
You can configure the usage time for every category, so you can have a different time for every day and every week. It is possible to combine both, so you can have 2 hours on Saturday and 1 hour on Sunday.
Moreover, you can set an extra time, so you can play for longer than you normally do. This can be used as bonus.
It is also possible to set the time limit for all apps.
The multi-user support is very useful, because it allows you to set the limit for all devices. It is possible to choose the connected device as the current device, so you can have a different limit for every device.
The settings are saved for the currently used app. It is possible to view and change the settings from any linked device.
