Realtor.com joins the Apps world

The National Associations of Realtor’s official website just announced the launch of its own App on the iPhone. The App will have about four million listings of houses and claims they will be updated every 15 minutes.

Zillow which provides real estate information as well did launch its own App for the iPhone last year. Both Zillow and Realtor will rely on the iPhone’s GPS to show your desired location and listings in the surrounding area.
