I think the only app that I've been using for a while now is this free, eye catching thing where you have followers on it an make them worship you, give you gold, and other stuff..
I'm already on level 37, which takes weeks by the way to complete, and I'm still not sick of it..
Imagine all the applications I bought on iTunes which is worthless and costs more than 5 bucks. Ugh..
