It would be handy if fruits and vegetables came with their own little decoder rings: How do you store fresh rhubarb again? Is that sweet corn genetically modified? Is the asparagus in season?

Farmanac allows you to solve these mysteries with just a few clicks on your smartphone. The app lets you search thousands of fruits and vegetables by name or PLU code. The info that pops up includes how to select and store them, toxin ratings, organic and GMO status, and when and where selected produce is in season. Farmanac even brings up a photo in case you find yourself doubting the label (“The tag says watercress, but I’m pretty sure that’s arugula”).
Available for iPhone, iPod touch and iPad for $1.99.
