Or you can get an iPhone and use parental controls. My kids has a tablet and I get to decide what can be used and for how long, and nothing gets installed without my approval.
Apple is really dropping the ball here, there are serious issues with parental controls on iOS.
No way to revoke install permission. e.g. child got ahold of a parent's unlocked phone, turned off parent approval for their own phone, and then installed a social media app. We have uninstalled the app, but he can re-install without requesting permissions. We have resorted to a 1-minute (the minimum) screen time limit instead. (Only work around would be to create a whole new iCloud account for the child!)
You used to be able to delete the purchase from purchase history, but now you can only hide it, hiding it should just retrigger the approval process?
There are well known / well documented ways to circumvent screen time limits.
You can't add additional pass code / authentication for the settings app or the parental controls
No way to prevent deletion of messages and call logs (and 3rd party tools just do a remote sync on Wi-Fi, after the kids already likely deleted them)
Parental controls are often janky or laggy and sometimes just don't work at all. And often require multiple re-authentication (iOS 18 / Face ID does improve this to be fair)
Your comment reads a bit silly to me. It’s like your child has control over this situation instead of you, and you’re trying your hardest to negotiate a good position for yourself.
If your child doesn’t use the phone in the way you want them to, you could take the phone away.
