The current release (2.2) has a problem but the author has a temporary fix while apple reviews 2.3...

I've run several tiddlywikis with it - one I used for my course website with my notes and all for each week, one that hold all my tasks and projects, and one I use to take notes about my advisees with. I used to back it up to tiddlyspot without a problem, but like dropbox now. The only plugin I've had a problem with is EasyEdit, but I think that could be an ipad issue. Reminder plugins, calendar ones, foreachtiddler, Udo's search plugin... even Eric's plugin that lets you embed pictures (of my advisees) in the tiddlywiki all work fine in twmobile.

TWEdit and TWMobile are at version 2.2.3 - and the referenced 2.2.2 problem was fixed with that release. I recommend TWEdit over TWMobile as TWEdit runs on both iPad and iPhone (the original iPad only app was called TWMobile but someone snagged that name in App Store before I got the iPhone version out - and so I had to create TWEdit as the app for both platforms - they run the same code base and I keep TWMobile going really only for those folks who bought it ahead of TWEdit).Version 2.3 is in test with a new file manager and full file system sync to dropbox, plus one or two other bits and pieces. Will get that out the door soon - or as soon as I feel 100% comfortable with it.
I'll be checking out TWEdit in the next couple days. Between the above and the description on the app store I'm unclear whether Dropbox syncing is available with the current version.
My regular TW is running in TWEdit without modification. The only problem is that fonts are very small for touch actuation of commands.
