How Can you Tell a Decoy App?

Identifying a decoy app can be challenging, but there are some clues that users can look for to determine if an app might be functioning as a decoy.

Remember that these indicators are not foolproof, and some legitimate apps may exhibit similar characteristics. However, here are some general guidelines:

  • Duplicate Icons: One common sign of a decoy app is the presence of duplicate icons for commonly used apps. For example, if you notice a second calculator icon on your device, it could potentially be a decoy app. Legitimate calculators are typically pre-installed on both Apple and Android devices, so a duplicate might raise suspicions.
  • Hidden Features During Setup: Decoy apps often have hidden functionalities that are revealed during the setup process. For instance, they may prompt users to set up a secondary password or gesture to access the hidden content.
  • Inconspicuous Names: Decoy apps might have names that do not clearly indicate their true purpose. They may use generic names like “Calculator,” “Notepad,” or “Settings,” making it less obvious that they are actually designed to hide private content.
  • Unusual Permissions: Check the app’s permission requests during installation. If an app requests permissions that seem unnecessary for its supposed functionality (such as accessing contacts, messages, or camera), it could be a sign that it has hidden features.
  • Reviews and Ratings: Pay attention to user reviews and ratings on the app store. If users mention suspicious behavior or hidden functionalities in their reviews, it’s worth investigating further.
  • App Behavior: Watch for unexpected behaviors, such as the app closing abruptly or behaving differently than its advertised purpose. Decoy apps may have additional security measures, such as closing the app with a shake or capturing intruder selfies, which are not typical of regular apps.
  • Hidden or Dual Passwords: Some decoy apps may require users to enter a second password or perform a specific action to access hidden content. If an app prompts you for a password or gesture that seems unnecessary for its primary function, it might be a decoy.
  • Trial and Error: If you suspect an app might be a decoy, you can perform trial and error by entering incorrect passwords or attempting to access hidden features. Legitimate apps typically have safeguards against unauthorized access, but decoy apps may reveal their true nature under such circumstances.


In a world where digital privacy is increasingly crucial, these secret decoy apps for Android offer a discreet and effective solution.

Whether you opt for the Calculator – Photo Vault, Private Photo Vault, Vaulty, Keepsafe, or Clock Vault, you can trust that your private content remains hidden in plain sight. Embrace the power of these apps to safeguard your memories, documents, and personal files from unauthorized access.

Your privacy deserves the best, and these decoy apps deliver just that.
