Yummi

Yummi is an app for people to find ice cream trucks live on a map and send ping requests to alert the drivers that customers are in the area. Food trucks are also visible on the map and can provide their food menu and services. Both ice cream and food truck profiles have the ability to setup their profile, menu and events. Guests (non driver) do not sign up and can use the app freely.
