Last fall, the Bloomberg administration launched NYC BigApps, a competition to design web and phone apps using a massive cache of city data. Dozens of developers entered, including the designer of this very blog, and we’re to report that the mayor announced tonight that her team’s Big Apple Ed came in third place overall. Granted a site all about school data may not be that useful to our readers—unless you’ve got kids in the city school system, of course—but the BigApps site is worth checking out because there are plenty of cool apps dealing with buildings, parks, and even one that lets you build a “walkability shed,” determining how walkable various neighborhoods in the city are based on individual criteria. Other personal favorites include a landmarks app, a bike rack app, and one called BldgBeat. Any strike your fancy?
