If you’re still on the fence about which iOS writing application is best for you, Federico Viticci tried out 40 different ones and then picked his favorite 4 to do a side-by-side comparison of. His only criteria was that the apps had to be available on iPhone and iPad, have Markdown support, and sync with Dropbox.

Viticci’s top choice ended up being [Writing Kit](http://getwritingkit.com/). Because of his recommendation I’ve been spending a bit of time in the app to see how it handles Markdown and syncing. I agree that it is a fine app. Though something I strongly dislike about it is the need to manually tap “Save” in order to sync/save your work to Dropbox.

However, something that I’ve instantly fallen in love with in Writing Kit is that on the iPad, [the left and right margins act as left and right arrow keys](https://shawnblanc.net.s3.amazonaws.com/img/writing-kit-margins.jpg). Tap the left margin to move the cursor one character to the left; tap the right margin to move the cursor one character to the right. This clever little feature is like *Pull to Refresh* — once you’ve used it it instantly feels natural and you miss it in every other app.
