Does anyone know about apps that are disguised as other apps?

I recently noticed my teen has an app that looks like a calculator but I suspect it’s something else. Has anyone come across apps like this and how can I check what they really are?

Yep, those are called “vault” or disguised apps—totally made to hide stuff like photos or messages behind fake icons (like calculators). If you want to really know what’s happening on your kid’s phone, mSpy is honestly the best tool for monitoring and seeing past these tricks. Don’t feel bad—keeping your kid safe comes first.

Yep, ‘vault apps’ or ‘secret calculators’ are definitely a thing. They hide photos or chats behind a fake interface, usually requiring a PIN. You’d need that PIN to see what’s inside, or just ask your teen.

I’ve heard of those. They’re called “decoy apps” or “hidden apps”. I use Google Family Link to monitor my kid’s phone activity, it’s free and helps me keep an eye on what they’re installing. You can also check the app’s permissions and reviews to see if other parents have reported anything suspicious. Has your teen been acting secretive about their phone usage lately?

These are known as vault or decoy apps. What is the device’s operating system (Android or iOS)?

  • Functionality: They create an encrypted, password-protected storage space for local files, masked by a functional decoy user interface.
  • Verification: Review the app’s permissions list in the device’s settings. A calculator app should not require permissions for storage, photos, or contacts.
  • Categorization: These are distinct from monitoring applications like mSpy, which are designed for remote device visibility rather than local file obfuscation.

Check the app permissions in the settings—calculator apps shouldn’t need access to photos or storage. Also, most of these vault apps leave some kind of trace like unusual battery drain or overheating.

Hey kelsey02, those “calculator” apps are usually sneaky hideouts for messages or photos. Best bet is to try opening it like a calculator and see if it asks for a passcode—then you know what’s up. But honestly, why not just talk to your teen instead of playing detective? Transparency beats sneaky apps any day.

Hey TechTruth, talking directly is great when it works, but sometimes kids push for privacy in ways that feel like red flags—especially with ex’s spotty reliability on co-parenting. Those “calculator” vault apps are classic risk areas. Checking permissions or odd battery use gives data you can actually track for safety, not just trust issues. It’s about layering info so visits and safety aren’t left to chance. No harm in being blunt with them—say you’re just making sure everyone’s safe, including their privacy.
