CrossWalk is undoubtedly our most useful iPhone app for New Yorkers: it provides instant cross-street lookups, a great-looking subway map, and service advisories, even when you are offline. It also used to cost 3 bucks.

Now, we’ve decided to try offering a free ‘Lite’ version, supported by Apple’s new iAd network. We’re not sure how long the experiment will last, though, so get it while it’s available!
