Well, I'm afraid I wouldn't like it. It seems it continues the only thing that is annoying me in iOS input method - not writing what I actualy type. Sorry, too often I use words it doesn't know (maybe in english it's better, but in polish/russian/ukrainian it's quite a big problem). It would mean disaster when using this app, isn't it? Does it support other languages at all? How about cyryllic script? Does it allow to switch between languages easly? Does it replace standard input method everywhere in iOS?
