The Facebook and Twitter apps are actually web services that require a username/password and their apps are merely extensions of their website. Does his app have a standalone service that would justify a username/password? Or would it be equivalent to forcing me to register to play a game like Plant vs Zombies, which has no functionality that would justify password protecting it.
