Free it is, which makes it kind of weird that some of the commenters were saying "Don't waste your money."
Okay ... downloading ... installing ... loading ... okay, pretty good, not great. It is rich in farmer's market info for Louisville and popped up right away with the St. Matthews, Bardstown Road, Rainbow Blossom and many more. If you tap the push pin image, you get the name of the market, and can tap that for more info. It's generally correct, but I can't help noticing that it shows a Thursday farmers' market at St. Matthew's Episcopal Church, which I know for a fact is not now and never has been correct. Hmm.
Anyway, it's amusing if not deeply detailed, and it might be great if you're traveling or visiting a new area. And you really can't complain about the price, which is $0.00.
