An app mockup is a visual representation of an app, typically created in a graphics editing program or wireframing tool. It is used to demonstrate the layout, design, and functionalities of an app before it is actually built.
App mockups can be created at different levels of detail and complexity, from simple wireframes that show the basic layout and structure of the app, to high-fidelity mockups that include detailed design elements such as colors, typography, and images.
App mockups are often used in the early stages of app design to explore different design ideas and get feedback from stakeholders. They can also be used to demonstrate the proposed design to clients or users and to get approval before proceeding with the actual development of the app.
Overall, app mockups are an important tool for visualizing and communicating the design of an app before it is built, and can help ensure that the final product meets the needs and goals of the business and the users.
