ZipRealty, Zillow launch iPad apps

Apps capitalize on larger-than-iPhone screen size

National real estate brokerage ZipRealty and property search and valuation site Zillow will roll out free Apple iPad applications for the device’s launch Saturday.

Zillow’s app will allow users to search for homes for sale and rentals on a large-screen map using landscape or portrait mode and flick through photos of one or more homes alongside the map, the company said. Zillow also created a photo-based shopping interface that allows users to "window shop" and compare homes side by side.
