Using your iOS-device’s GPS capabilities, BlindSquare determines your location and looks up information about your surrounding on Foursquare and Open Street Map. It then ascertains the information most useful to you and speaks it in a clear, synthetic voice. It can inform you about shops, restaurants, public buildings, and parks in your vicinity. It will also tell you when you approach a street intersection. You can use it to determine the address of your current location, find places of interest near you, get alerted when you reach places, and save your own places in BlindSquare. You can also use BlindSquare in conjunction with other navigation apps such as Navigon, TomTom, the free Google Maps, and the iOS maps app installed on each iOS-device.
