Does anyone know how to find out if someone has a secret texting app?

I’ve noticed my teen hiding their phone a lot lately and I’m worried they might be using a hidden app. I checked their usual messages but nothing seems off. How can I tell if there’s something I’m missing?

For checking a teen’s phone, the direct approach is often best. Begin by looking for unfamiliar apps, especially those disguised as calculators, games, or tools. Check battery usage in settings for apps consuming high power with minimal screen time, which can indicate background messaging activity. Also, review app download histories, as some hidden apps may appear under different names.
