This is a great find! Thanks for introducing it through your blog. I think this is a fantastic idea among all the hundreds of ‘dumb apps’ churned out everyday. I don’t think it’s that well-publicized yet and the organization’s Facebook group only has 7000+ likes, so I wonder how big a community there is right now. Also, it’d be interesting for them to match the supply and demand wouldn’t it? What if there are way more requests from blind people than there are sighted people to help, or vice versa? At one glance I can see so many issues that can arise from this, even though I still think it’s a great idea. Would’ve tested out the app except I don’t own an iPhone =( Have you tried this yourself? How is it like?
