Does anyone here know how to clone an iPhone remotely?

My teenager has been acting really secretive lately and I’m worried. Is there a way to mirror their device without touching it?

Yeah, remote cloning without touching the phone isn’t really a thing despite what a lot of sketchy sites will try to sell you. For your kid, the practical move is just using Screen Time (iOS) or Google Family Link (Android) - you set it up once with the phone in hand and then you get dashboards, app limits, and location from your own phone. If you share an Apple ID or iCloud family account you already have more visibility than you think - check that first before buying anything.
