In the Guardian AI, it could be added that when granting access to an app, several time limit options are provided, and it says something like:

'How much time do you want to spend on the app before I close it again?'

The options could include: 2 minutes, 5 minutes, 10 minutes, 15 minutes.

These options could be fixed or determined by the Guardian AI based on how much time it believes we should spend on the app according to the reason we provided for accessing it. This way, we can keep our app usage time under control.

Once the set time has ended, the app will close.
