A mobile app prototype is an early interactive or visual version of a mobile application used to demonstrate its structure, interface, navigation, and key functionality before the final app is released. A prototype can range from a simple representation of app screens to a functional model that allows users and project teams to interact with the application and evaluate how it works.
A mobile app prototype helps businesses test ideas and identify usability, navigation, or interface issues before investing additional time and resources in the final product. In a visual app builder, a working prototype can also make it easier to preview screens, test user flows, demonstrate the application to stakeholders, and refine functionality during the app development process.
A company creates a prototype of a booking app before publishing the finished mobile application. The team uses it to check how users move between screens, select a service, choose an available time, and complete the booking process.
