Disco Secrets

Welcome to the Black Book app with a difference. Sure most black book apps allow you to assign a password, but having the app installed on your phone makes something quite obvious doesn't it? You have a need for a black book app.
Well not this time. Go ahead and support me as a developer by downloading this funky and mostly useless disco app. Enter the app and your phone will go into a funky disco light mode of flashing colours.
Once you are done with your little lie double tap the screen and pinch zoom in in one gesture. Oh what's this? A hidden element of the app? Welcome to your new black book - but if anyone asks it's just a disco. The rest is our little secret ;-)
