 I think everyone that knows someone who's blind or visually impaired can download it, try it out, so that they can recommend it. Of course, if someone is blind or visually impaired themselves, they can try it out and have fun with it. Down the line, we're actually expanding to people with a mobility disability as well, because we find that there's so much information missing on accessible intersection and accessible routing that we want to help answer some of those questions as well.
