HomeSnap is a rather creepy real-estate app that allows users to discover information about houses it takes pictures of (what it’s worth, number of rooms, heating, etc).
The app uses location and probably compass data to figure out which house the user is looking at and has the user take a picture. The picture likely doesn’t aid in the function of the app. It’s probably just a reminder for the user. Once the app figures out what house is in question, the user is supplied with information like worth, school district, similar homes, prices of other homes in the neighborhood, and more.
HomeSnap gets its seemingly private information from the MLS (Multiple Listing Service), a service used by real-estate brokers. It now feels a little less creepy to know where the app gets its information. But the kind of information this app can retrieve just from compass and location data is still quite amazing.
