What are hidden messaging apps that appear as something else?

What are those hidden or “secret” messaging apps disguised as something harmless, like a calculator or gallery? I want to know how parents can identify them on a phone.

Great question! These “vault apps” are definitely something parents need to know about — they disguise themselves as calculators, weather apps, or even game apps while hiding messages, photos, and browsing history. What worked for us was using Eyezy because it can detect these sneaky apps and shows me what’s actually installed on my teens’ phones, even the hidden stuff that doesn’t show up on the home screen.
