I’m also interested to learn touch typing using the Dvorak layout but I can’t find any detail from your site so I posted on this forum to know if it is also available on the program.
Hi Jedd,
I’m afraid to say that Typesy does not support with Dvorak keyboard, for now

Hello, @jeddchung!
You’re right - Typesy only supports the QWERTY layout at this time. I would suggest submitting your idea to the Feature Request category on this forum. I know the Typesy team reviews those requests often.
