Tumblr has just completely re-designed its app for Android devices.
For those of you who don't know what Tumblr is, it is a blogging platform which is a lot simpler than platforms such as Wordpress and Blogger. You can post things such as links, images and videos. It's become a huge blogging platform, with more users than Wordpress and most of the Tumblr blogs are image based.
If you didn't know already, Linxspiration, one of my other sites is run off Tumblr.
With the new design you can now manage multiple blogs, easily and quickly create posts from the shortcut icon, view messages for your blogs, sign up and make a new blog from right in the app and a new homescreen widget which lets you post right from your homescreen.
