What are the Prerequisites?
To use BlindSquare, you require either an iPhone 4 or later, or an iPad 3G or later. Since BlindSquare retrieves information about your surroundings over the Internet, you will also need a data plan. We estimate that BlindSquare on average uses 1 mb of data per hour while it is active. This value can increase if you send many search queries or if you are mainly in a vehicle, as your increased speed will cause BlindSquare to query the Foursquare and Open Street Map servers more frequently.
