The Good: Tumblr for Android has a beautiful and dead simple interface with nifty navigation buttons. The Bad: Animated GIFs don't show up in the Home feed. There's no landscape support or tablet-optimized version. The Bottom Line: Despite its minor imperfections, this app is a must-have for any Tumblr user. With the newly updated Tumblr for Android, using the megapopular blogging platform cum social network while on the go is a snap. The app lets you create and publish posts, read through posts by bloggers you follow, and manage your account settings, all through a beautiful interface with crisp images and dead simple navigation. And if you're not already a Tumblr user, you can even create an account right from the app.Just like when you sign on to Tumblr on the Web, the Android app opens you up directly to your Dashboard, where you see your main feed, with all the newest posts from the blogs you follow. Things are arranged reverse-chronologically, so you can scroll down to see older posts. As you get closer the bottom of the screen, the app will even automatically reload, so you can scroll virtually forever. To refresh the listing of posts, you can pull down from the top The interface on the Dashboard looks and feels very much like it does on the full Web version of Tumblr, except for a few items. For one, all images are static, which is a huge disappointment, since animated GIFs are such a big part of the Tumblr community. As it is now, the app forces you to click through on these GIFs to see their animations in action, and this can get annoying if you're used to quickly sifting through your feed. Also, the dashboard doesn't include Spotlighted Tumblr users like it does on the Web, which leaves you with fewer channels for discovering new content.
