What are some cool iphone apps?

I'm saving up for an iphone (5). Its my first iphone, I've had the ipod touch but it broke after 2 years, haha and last I heard everyone was obsessing over temple run and simsimi. So its been a while!

Getting to the point, what are some cool apps a 15 year old girl would enjoy?

I know about
-pudding camera
-instagram
-snapchat
-fb, twitter, tumblr

but what else should I get?
. Preferably free

Wanelo. Its an app/website that has all these cool clothes and stuff, and you can save things to collections and most of the cute stuff is actually really cheap to buy. But of course you don't actually have to buy stuff. Its just a fun app and its a good time passer.iFunny is another i enjoy. Its basically just lots of funny pictures and jokes but its interfaced really well! They are both free and i couldn't live without them.

If you like to shop, then there's this cool app called ShopKick and whenever you go into a store you can get what they call "kicks" and if you save up enough "kicks" then you redeem them for gift cards and other stuff.
