Lockdown Pro is very simple to set up and start using. When you first run the app youll be prompted to enter a passcode or pattern. Once youve done this youll need to use this code every time you want to access the app.
Locking applications is as easy as tapping a button next to the app you want to lock from the list in the main menu of Lockdown Pro. You can see at the top of the list the total number of apps that have been locked. Theres no way to automatically select all applications to lock them.
Overall, Lockdown Pro performs great, though it would be nice to have the option to lock the screen via the app.
