Work before play app

[Tireddad]

I wonder if there is an app for my situation .i have 2 kids who like to play with my ipad but I would love an app whereby
They have to play something like " mathletics" for say 10 minutes before they are then rewarded with say 20 minutes of
free play. I have searched the App Store but perhaps I am not using the right search terms or there is nothing like that .

The closest thing to what you want is Guided Access. You can lock down an iPad to a specific app, and even prevent certain actions within that app. However it is not automatic. You have to turn it on and off yourself.
