I've looked at quite a few text word/text processors for the iPad and most of them come up pretty short. Pages, as an example, seems more of a "create pretty documents" app than a heavy-duty text processor.
Textkraft (US$3.99) is likely the app you crave. It's powerful, easy to use and provides a writing environment you can do real work in.
Here are some of the top features I found appealing:
- You can work on up to five documents at once, switching between them with a tap.
- Cursor keys support, something lacking in the Apple solutions
- Complete undo/redo
- Full search and replace
- Support for external Bluetooth keyboards
- Import and export with Dropbox, iCloud, Box and iTunes file sharing
- Sharing with Pages and Evernote
There's more, so check the app's website or the App Store description.
Using the app is straightforward, but as I first started to type, I was taken aback by a large mid-screen display of words in boxes that changes as I typed. The app was suggesting other words I could use, checking spelling and providing alternates. There are lots of suggestions. It's powerful, but I found it distracting. Happily, the feature can be hidden.
