If you live in a major city, you probably pass at least a few pieces of eye-catching architecture on your daily commute—but have you ever wondered who was behind them, or what they look like inside?
Buildings, a new free iPhone app by Despark Ltd., the people behind the great Open Buildings site, allows you to find, learn about, and share the architecture in your local area and around the world. Like a Wikipedia for architecture, Buildings has a user-generated database of structures. But where it truly shines is in the depth of information it offers: You can browse photos, videos, and comments by other users; check in a la Foursquare; or easily add your own photos and videos using your device's camera.
You can download the free app and start engaging with your city's buildings here.
