Are there any spyware programs or apps i can download onto an iphone for free?

I'm looking for an app or a program that will show me texts.internet usage and all the good stuff… Not on my phone of course. Its for my son. I thnk he is involved with some bad stuff and id like to get to the bottom of things before anything happen s to him. I don't want him to know the app or program is. On his phone. And it'd be nice if. It were free.

Not that I know of, that would be like a virus and they don't allow that junk.

Restrictions

I think you can Download an Antivirus and set Parental Controls or Restricitons on it.
