Unlike almost all apps discussed here, Nearby Explorer is not available in the South African app store.
I have written to the American Printing House for the Blind to ask them to make it available in the South African app store. We have pretty detailed FourSquare and Google maps here, so it should work well. I have received no response from them. I will write again.
Do people in other parts of the world have access to the app? If not, then i'd advise people against voting for the American Printing House for the Blind in the apple vis awards. A great app is of limited use if most of the world's blind people can't access it.
