How to make an application that blocks Internet traffic or the launch of other applications and pass moderation?

Question

iOS

Hello,
there is an idea to make a motivator for the user, he downloads it, sets the required number of minutes, during which he must do physical. the load that we monitor by phone sensors - and then it can continue to use the Internet.
If he didn’t, then the application blocks the Internet or Instagram for example.
Question. Is it possible to do it on iphone and pass moderation? I heard that apple does not allow you to control internet traffic or block other applications.
There was also an idea to make it like a VPN application to let traffic through our server part, and we would already be there through TOR, but again, will the moderators let our application through?
I repeat - we will write everything in the description so that users consciously install such an application.

Answer 1

You will not be able to access the phone's system functions. Accordingly, you will not be able to climb other applications, or disable instagram. This is only possible on root Android ... So, either motivate with notifications, or not at all))
