Secret calculator app definition: what "Secret calculator app" means and examples

February 9, 2026

An app that disguises a hidden vault as a standard, functioning calculator.

This is an important one for parental awareness. On the surface, it looks and works like a normal calculator. However, if a secret PIN is entered, it opens a hidden folder containing photos, videos, or messages that the user wants to keep private. It is a common way for teenagers to hide content they don't want their parents (or anyone else) to find during a phone check.

Examples:

  1. "I saw a secret calculator app on his phone and I'm worried what’s in it."
  2. "If you see two calculators on a phone, one is probably a secret calculator app."
  3. "He used a secret calculator app to hide his social media passwords."
