The Whitelist is the list of useful apps that you're permitted to access while you're Flipd Off. From the Whitelist, you can check off which apps you would like to use and then you will be able to access these apps from the lock screen while Flipd Off. In the free version you can choose from our default Whitelist, and in the Premium version you can choose up to 3 additional apps of your choice to add to the Whitelist.
