Shopping for produce and other fresh foods, especially in New York City, can be a crapshoot, but Thinkenhaus removes some of the guesswork with the FarmFresh NYC iPhone App. The guide points professional and amateur cooks to local farmers markets selling in-season fruit, vegetables, fish and shellfish. There are 90 products in all and 50 participating farmers markets. Updates are automatic, and you can even create a grocery list or track the seasonality of individual items. That sounds a lot more appetizing than wading through piles of mushy tomatoes at the local bodega. FarmFresh NYC is available from the App Store now for $3, and versions for San Francisco, Los Angeles, Chicago and New Orleans are on the way. [via Thinkenhaus]
