APP DESIGN CONCEPT. Mobile app design for Spongedrop Cakery at Mount Maunganui. The business currently uses a website for orders. I have applied the current design system used on the website (colour scheme, iconography and typography) to the app. The app features all the main areas of the website (all categories for ordering, account settings and speciality orders). The new addition added to the app is a delivery service. Whilst Spongedrop does not currently offer a delivery service, this could be an additional aspect added on later or could be used to notify customers once their order is ready at the store for collection.
