The app can be set to automatically change the PIN to your phone to the current time, but you will need to pick a time format beforehand. You can set an offset PIN or reverse PIN inside the app. This means that you no longer need to remember a set of numbers in order to unlock your phone, just the offset. The app provides increased security, since the PIN actually changes every minute.
 
Smart Phone Lock also lets you change the lock screen PIN to the current date or you can hide the app icon from the launcher. In this case, the app would be launched when you type a code in the phone dialer.
