TypeWay - Ralf Trachte

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, and has a quasi-full
keyboard, and sets focus on 10-finger touch typing.
With “Save” / “Restore” and “Freeze”, you can fix
a customized / personalized keyboard configuration.
Layout:  English international, or German, in landscape mode.
Special characters like “ä ö ü æ å ç [ ]” via the option key “⌥”.
Optional slanted default keyboard layout, font size settings,
“Open In…” (e.g., Mail, Pages, Word, DropBox, Evernote).
It also works as a general keyboard in various iPad apps (“third-party keyboard”).
Actually, the App Store Preview page shows the screenshots of the iPad Pro;
