Of course it’s a little redundant to have an app which you can already do on the web, but this is great.
WordPress have released their App for blogging.
The interface is clean and easy to follow. All you need to do is add the blogs that you operate either on your own site or on the wordpress.com (free) site, Add url, username and password and you are up and running.
You can edit any posts, add photos just taken, there’s even a live preview.
Only just started playing with it, but it’s already going to be invaluable.
