Following the announcement of mobile ads, Tumblr today released a new version of its iOS app, adding several new social and usability features.

Although readers were previously able to reblog posts on the platform, there wasn’t an easy way to share them with friends on social networks. Recognizing that content thrives beyond the platform, Tumblr has enabled Twitter and Facebook sharing features which are now embedded in the app.

The company has also launched a new template for email sharing, allowing the recipient to either read your post in his or her mail client or click through to view it within the Tumblr app. And for those that can’t read right away, Tumblr now includes Pocket and Instapaper so people can save content and read it later.

Other improvements include GIFs that animate, even while you scroll, and an alphabetized and searchable “Following” list. The GIF animation only works on iPhone 4S or later and iPad 2 or later.

Until now, readers using Apple mobile devices hasn’t had additional sharing features — while Android and even Windows Phone supported easy sharing between apps. Today’s update will hopefully help Tumblr feed traffic back to its service and help you get more eyes on your content.

Remember, if you’re sharing on Tumblr, the blogging platform favors quick, visual updates. It can be a challenge to effectively capture your message in a concise and easily sharable way, but it’s definitely doable. Many brands from a variety of different industries are making the most out of Tumblr. Take a look at our examples of how a few of them are succeeding.
