Nice. I made a similar thing as a TamperMonkey script that I can turn on and off on any website, it even includes a speed-controlled-voice that can read it for me.

One small annoyance with your app is the instructions in the welcome were tiny. Took me well over a minute to figure out how to control the thing, until I finally found those small hand icons in the right corner. You should consider adding these to the first page of welcome using a large-er size or something.
