I recently bought the In-app purchase within Byword to try and blog straight from the app. Up until now, my workflow has been to write in Byword or Writer Pro, copy the html into the WordPress app, and then add screenshots processed by the Screenshot app before publishing.
Byword’s most recent update claims it can cut out one of the middle men by allowing me to publish to WordPress and add pictures straight from the app. I tried it out quickly today with this post and am quite impressed with how simple and easy it turned out to be. It’s definitely buggy on the iOS 8 beta, but this seems like a great workable solution for blogging from the iPad, without feeling like I’m using all sorts of workarounds.

My name is probably Thomas (yes, it is). I'll be able to help you figure out why Evernote isn't syncing, or recommend your favourite new RSS reader to you. That's partly because I am enamoured with the iOS ecosystem and hardware, but mostly because I'm Canadian.

Have you ever tried Blogsy?
I have, but found it a little clunky after a while. I still keep it around but prefer to just write in Markdown and just add images after-the-fact.
How does this differ from using the free WordPress app?
Byword lets me write in Markdown and then export that into HTML with the images. WordPress can only do HTML, and I don’t like keeping drafts in the app. I’d prefer to have them in a text editing.
