I can't really use the physical dice because there are good and bad dice of the same shape (I've already wished for braille dice for EotE). I hated having people build my pools for me and put them in my hand so I could roll then and they would then read them. I let other people just roll my dice after a while. Getting everyone to put the dice in a specific spot so I could pick them to make my pools was annoying. So I love the dice app.
Hmm. I don't think you need Braille dice, just ones with the symbols etched into them. The symbols are pretty distinct.
