TypeWay

TypeWay - Ralf Trachte

Customize your keyboard by a simultaneous intelligent 
multi-touch adaptation or a stored favorite layout.   

TypeWay supports 10-finger typing with automatic adaptation
of the configuration.  It uses iPad’s multi-touch technology
to sense up to 10 touches simultaneously, has a
full keyboard, and sets focus on 10-finger touch typing.
For beginners, we recommend a frozen layout:
With “Save” (& “Restore”) and “Freeze,” you can fix
a customized, personalized keyboard configuration.

Layout:  US English, British English or German, in landscape mode.
Special characters like  “ä ö æ å ç [ ] « »”  via the Alt key ⌥  (and Shift Alt).
It works as a general keyboard in various iPad applications  (third-party keyboard)
or as a separate note-taker app.
( The app is NOT for a Mac.  It might need too much space for an iPad mini.
  It has no text prediction. )

Price:  $ 0.99  or local equivalent
