Apps for fruits and veggies

I've been looking for apps that will help me learn more about fresh fruits and vegetables. They could be helpful while shopping at a grocery store or local farmer's market. Ideally it would provide pictures, a description, nutritional information, recipes and seasonal availability.

I just installed "specialty produce," "seasonal and simple," and "evernote food" and will give them a try. I have an android phone but they are likely also available for the iPhone.

Does anyone have others they can recommend?
