This app is best known for providing mobile access to website Zillow.com's popular "Zestimates" -- projected current market values for virtually every home in America. Zillow calculates Zestimates using special algorithms that compare each property's square footage and other characteristics to those of recently sold nearby homes.
A relative newcomer among house-hunting apps, HomeSnap is getting rave reviews for its ability to let you take a snapshot of a home using your smartphone's camera and instantly get information about the property. You can find out the home's estimated value, along with whether it's for sale and how many bedrooms, bathrooms and other amenities it has. Even if the home isn't available, HomeSnap will show you other nearby listings that are. That said, the app's ability to find homes using your smartphone's camera is something of a gimmick. While you can store snapshots you take or even share them with friends, HomeSnap doesn't actually use photo-recognition software to figure out what house you're looking at. Instead, the app uses your phone's GPS to determine where you are and what property you've just photographed.
