Dobee

Dobee allows children to earn screen-time by solving math puzzles (other exercises and tasks to be added). This way, the balance between entertainment and training is achieved.

This app uses the Device Administrator permission to prevent children from uninstalling Dobee. Parents can easily deactivate this permission from within the app's menu.

For monitoring how kids spend their time on devices, Dobee uses Accessibility Service, which should be enabled during initial setup.
