Being a locavore just got a whole lot easier. Locavore, a new iPhone app available (for $3 for the first 1,000 customers) on iTunes, uses GPS to pinpoint where you are and tell you a) what local produce is in season b) which nearby markets offer locally grown foods and c) when your brownies are done. (Just making sure you're paying attention.) There are 234 foods in the Locavore database, as well -- just tap on the display to find out when and where they are grown and in season. If I only had an iPhone.
