And I still fail to understand how it will work with a graphical app.

Perhaps you should try it? Got any rich friends with an iPhone you could
borrow for a couple of hours??

It would probably work on one of my iPads. And maybe there's an Android
equivalent or two; there usually are. But as it's of no relevance to me, I
don't think I'll bother.

If you are happy to fail to understand, then don't bleat about it here.
