Androblogger is an app that connect you with your blog on the Blogger, the blogspot website by Google.
With this client you can write new post, edit already existing one and read comments.
Androblogger allows you format text in the post. And also you can save drafts of your posts.
You can see, this app has very simple and clear interface to use. And it works fast without any errors.
But some features such as picture upload (now you can upload picture only from website), multiple blogs and adding tags is still missing. Hopefully these features will be added in future updates to this app, but anyway it does make mobile blogging much easier.
