Americanize it you mean. No thank you
Actually I think the app is learning to interpret my handwriting. And probably I am adapting it a little too. The progress is quite impressive. Yesterday I was unable to complete a decent-sized sentence, this morning I wrote a small paragraph. There are still errors, but at this stage the number of errors seems to be about the same as when I write with the iOS keyboard. Maybe slightly higher still, but hopefully it will keep improving.
