The truth: I hardly use iOS Scrivener any more.
It’s just too limited compared to Mac Scrivener (or even Windows Scrivener). I can never see the aspects of my project that I really want to see. There’s no Scrivenings mode. There are no collections. The Corkboard only ever shows one level of one folder. Keywords and custom metadata are missing.
It goes on. I self-publish, and the facilities to produce a manuscript that’s ready to upload to Amazon and Smashwords just aren’t there. The iOS Scrivener compiler has few features compared to Mac or Windows.
As for research, I don’t use Scrivener at all for that. I use Evernote instead. It’s much easier to find what I need there, and I can display Evernote on a second screen on Mac. On the rare occasions when I use iOS Scrivener these days, I can split the screen between Scrivener and Evernote. I really don’t like my research crammed into the same app as my manuscript. (N.B.: This is Scrivener heresy. One of its heavy selling points is keeping research and manuscript together. I’ve tried it. Every third project, it seems, I try it again just to see if it works better than Evernote. The answer has always been no so far.)
So iOS Scrivener doesn’t work well for me for either planning or publishing. Its lack of easily configurable overview makes it less than ideal for drafting. The only time I find myself using it is when I want to jump start my actual word production for the day by using handwriting recognition. But since I found a workaround to use handwriting recognition with my Mac, I don’t even use iOS Scrivener for that any more.
It’s not a bad app, iOS Scrivener. I like it. If Mac Scrivener didn’t exist, or if I had only an iPad, it would be my writing app. But as I have a lovely tiny Macbook Air 11, I just don’t use it.
