Zillow iPhone app allows you to view real estate information on every home around you — as you move.

Walk or drive through a neighborhood and see estimated home values, homes for sale, recently sold homes.

GPS technology pinpoints your location and then displays real-time real estate information and data as you go. You can also search any neighborhood, regardless of your location.

Zillow has at least some data on 95 percent of the homes in the country, including photos and contact information for 3.4 million for-sale listings.
