The Goby search engine, which helps you find things to do with your free time, released their Goby iPhone app last month (free), and it quickly jumped to being one of the leading free apps in the Travel category in the iTunes store. It covers every town and city in the U.S. and contains over 4 million things to do. It's location-aware, so it automatically knows where you are when you want to find something nearby. Plus, it also alerts you to current and upcoming events in the area.
