Zoocasa, the Canadian real estate and Google Maps mashup, has released an iPhone application. The application allows users to find homes near their current location using the iPhone's built in GPS.
The available properties are shown on a Google Map. It is possible to get descriptions and photographs of each property and it is even possible to get directions to help you find a house. House hunters can search for available properties on their phones by price, number of bedrooms and by location.
The application is available from iTunes.
