The leaderboard with acorns is a smart touch. gamification might actually solve your price freshness problem better than anything else. If updating a price earned acorns too, your top contributors would keep the data current for you. Nice project, and the 10% to food banks commitment on the about page is a good look.

Thank you! Yes, updating prices give you acorn and badge as well. I might expand more incentives to update prices, like suggestion from comments, for restaurants.

Food bank commitment is built in from start. I plan to display transparent donation amount if we ever make money. (fingers crossed!)
