Dasher is a text entry method completely unlike a keyboard. You just swipe and like a video game you navigate through the possible sentences you could be writing.
Check the demo:
I like the idea that you are just navigating through the Borgesian infinite library to extract your sentences.
Dasher is free and GPL, it just hasn’t been compiled for android yet. Compile it, sell it with source for $.99.
Remember, qwerty is not destiny.
