Hi Bob. Nice to hear from you. I got a 10" Samsung. You can spread the image till the ink hits the edge, so that helps readability.
My bigger tablet had viewing angle issues and faint image. This one looks better.

Whilst musing on these things I got it. On Drive, whilst viewing my file, I hit the 3-dot menu top right and spied "Open with...". iReal was on the list, so deed done.
