There's a mobile app that shows people the best french fries around them. The app would figure out their location and the user can set a radius and it should show them icons with ratings and prices. The app does consider store hours and holidays.
On the backend, there's a web application where french fry sellers can create an account, post their french fry details, get people to review them, and then also update pricing for their fries as it changes - which can be multiple times per day.
Who knew french fry prices were so volatile?!
