The initial and current release is available for download in the android market and equips with the ability to manage your blog while on the move. 

The WordPress App for Android Phones has the following notable features among many:

* Support for both WordPress.com blogs and self hosted wordpress blogs
* Ability to configure and manage multiple wordpress blogs
* Total Comment Management: comment moderation and the ability to reply to comments
* Publish new posts & pages including categories, tags and photos and edit the old ones
* Comment Notifications in the Android notification bar

Here are a few screenshots:

The popular android app for wordpress - wptogo - which already existed has ceased to undergo any further development as the developer of wptogo has himself worked with the automattic team to release the Official WordPress Blogging Tool for Android. (source) Those who have been using wptogo won't notice much of a difference in the Official WordPress For Android as the source(zip) from wpToGo powers the WordPress app. You can see this video of the app at work.
