This summer I used Scrivener’s iOS app (in its beta form!) as my primary app for writing at a week away. Even in its beta form it was good.
I’ve written about the desktop app here and here. You can read about my eight most-used features on iOS here.
Just today the price has come down from $19.99 on iOS to $11.99–easily worth it if you’ve got the means. Check it out here.
Words on the Word 
I saw they reduced the price, but I wasn’t sure if I should get it. I have it on my desktop and love it. You’d recommend it?
Yes, definitely! You can see screenshots at the hyperlink to my “8 features” post on Scrivener iOS, but I think it pretty much boils down to: if you use an iOS device and want to be able to access/edit/add to writing projects on it, then it’s something to have. Especially since the Dropbox sync functionality is there–I haven’t lost any data, either!
