Yikes. I have 121 apps on my iPhone. 😱 The thing is, I use almost all of them at least 2 or 3 times a week...except for the games. I have a ridiculous number of games on here. I think I have game ADD. Some of the games I haven't gotten around to playing yet! In my defense, I track the ones I know I eventually want to play until they go on sale or free. I buy them even if I am not planning on using them yet when they are heavily discounted. I figure I'll get around to them eventually...
I have mainly certain categories of apps: games, shopping, news/websurfing, music, and food related (including recipe apps, urbanspoon, etc).
Edit to add: now I am going to try to delete some... LOL
