Scope(Facebook,Twitter,Tumblr) Favorite all-in-one social media app, especially for viewing photos/videos and cross-sharing them. This is how I impress my facebook friends with all the awesome tumblr photos I find.

Foursquare Sometimes I like to dig deeper into venues, see specials, discover new places, etc. With active friends, foursquare is a lot of fun.

Panorama beta Super simple panorama creator. My phone's camera doesn't have this feature natively. This app makes up for it
