The Whitelist is the list of useful apps that you're permitted to access while you're Flipd Off in Full Lock mode. With the Whitelist enabled, you can Flip Off in a Full Lock and still use your device's default apps like Phone, Calculator, Notepad, Camera, Messages and a few others. When you've opened a Whitelisted App you can't leave the app to use something else.

  1. Flipd > Settings > Enable Whitelist
  2. Scroll and select Flipd as an Accessiblity App
  3. Reopen Flipd
  4. Select Full Lock icon and Flip Off
  5. Tap top left corner of Flipd screen to open the Whitelist
