I feel like there is a big opportunity for a mobile grocery shopping app. I don't want something to help me make a grocery list, I want something to hold and geek out with while I'm shopping to make informed decisions.

Often I visit the farmers market and I haven't a clue what a good deal produce is. No fliers involved. I want plots of average prices in the correct units. Are the prices lower than average for this season? I want to know how to pick good/ripe produce.

AnyLeaf looks like a good step in that direction...
