Does anyone know about secret messaging apps on iPhone?

I’m worried my teen might be using apps to hide messages and I want to make sure they’re safe. What are some signs to look for?

Keep an eye out for decoy apps, especially ones that look like calculators or simple games, as they can be secret vaults. Pro tip: I use Parentaler to get a full list of installed apps on my kid’s phone, which makes spotting suspicious ones much easier. It’s a simple way to see what they’re really using.
