Just as the housing market changes, so does the world of technology. Sometimes, they do so together.

The iPad, Apple’s new tablet computer, has not been on the market very long, but real estate companies have already been transitioning their features to the new platform, with the goal of helping you find and purchase a home – all on the go. Here’s a look at two of the first to hit the market.

Zillow
The iPad app for the popular real estate site (zillow.com) lets homebuyers search for homes for sale or rent and filter the searches by price, the number of beds and baths in the home or potential monthly payments. Buyers can view full-screen color photos on the iPad’s 10-inch touch screen and can easily drag-and-drop homes into a favorites section. Zestimates – Zillow’s proprietary home-value system – are available, as are Push notifications of new listings. You can view side-by-side photos of homes as you move from neighborhood to neighborhood, expand photos from Apple’s Stacks feature and even e-mail and share listings on Facebook.

ZipRealty
The iPad app for ZipRealty.com features more than 1 million MLS-listed homes for sale in 36 markets in 22 states and Washington, D.C. New listings, price reductions and foreclosures are updated daily. Buyers can search for homes by ZIP code, price, location and size, and even search recently sold home prices. Home-value estimates are available from Cyberhomes and Eppraisal. Details on homes for sale in more than 4,000 cities are available with GPS mapping service, which also provides location-aware service and driving directions to help buyers between viewings. Buyers can tap the screen to view details of any home with HomeScan™ technology, including asking/sold price and distance from you. One-touch access also connects buyers to their Zip agent.
