I have another (albeit more expensive) workflow. I use texpad[0] on my Mac and iPad, with the files stored in Dropbox and iCloud. Works like a charm and almost no overhead setting up.
This actually used to be my setup too. But Texpad on iOS is not very good (e.g. no multitasking support). Its Dropbox sync is not very reliable in my experience.
Then I moved to TeX Writer and Dropbox, which worked better. Then I wanted more (code completion, version control). So I ended up with the workflow mentioned in the article.
