Tumblr 3.0

Price: Free

Platform(s):iOS

For the third iteration of the Tumblr app, David Karp's team rebuilt its iOS app from the ground up. The result is a faster, cleaner, and more feature-filled app. There's now support for high-res images, Spotify, and offline access. There are also cool new gesture-based controls for thins like composing a post or taking a photo. They won't speed up your posting, but it's a nice, thoughtful touch. The same can be said for the app as a whole.
