A React Native module for identifying jail-broken, rooted, or mock locations on iOS and Android.


Are users claiming they are crossing the globe in seconds and collecting all the Pokeballs? Some apps need to protect themselves in order to protect data integrity. JailMonkey allows you to:

  • Identify if a phone has been jail-broken or rooted for iOS/Android.
  • Detect mocked locations for phones set in "developer mode".
  • (ANDROID ONLY) Detect if the application is running on external storage such as an SD card.


import JailMonkey from 'jail-monkey'

// is this device JailBroken on iOS/Android?

// Can this device mock location - no need to root!

// Check if device violates any of the above

// (ANDROID ONLY) Check if application is running on external storage


:exclamation: Since emulators are usually rooted, you might want to bypass these checks during development. Unless you're keen on constant false alarms :alarm_clock:


npm i jail-monkey --save
react-native link

If you use rnpm, you may have trouble as rnpm does not link Android properly after 0.29.0!
