HomesnapHomesnap goes a more creative route than some of the other apps, allowing users to find out more about places they already like. Snap a photo with Homesnap and it will give you the 4-1-1 on your Malibu dream home. You mean it costs, HOW MUCH!? Now that the housing market is rebounding, the app helps you identify which homes have good "investment potential." "Appreciation potential" shows you homes that Homesnap thinks you'll be able to flip. The app also has a social component. Store your favorites and see what your friends are looking at. Let's just hope you're not bidding for the same one. This free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 5.0 or later. It is also available for Android.
