App mockup

App mockup definition: Role in app design, importance & more

What is an app mockup?

An app mockup is a visual representation of your app's design. It's like a sneak peek into your app's appearance and function. It doesn't have the actual functionality but showcases your app's layout, user interface and overall design elements. Think of app mockups as screenshots of your app.

App mockups help you, designers and developers visualise the app's appearance and make necessary changes before diving into the actual development process of your app.

What are the different stages of app design and development?

An app’s design process typically involves three main stages: wireframing, mockup and prototype. Let's break them down:





Basic layout sketch

Detailed visual representation

Interactive and functional simulation

Tools required

Digital sketches

Graphic design software

Interactive software


Initial stage

Before development stage

After design approval


Basic blueprint

Visual representation

Interactive app simulation


At the initial stage, designers create low-fidelity wireframes. These are simple digital sketches that outline your app's layout and structure.

Wireframes focus on content placement, user flow and functionality without diving into visual design details. They serve as a blueprint for your app's architecture and help define its core elements.


In the next stage, designers develop medium-fidelity mockups. These are more refined visual representations of your app's user interface (UI) and design.

Mockups lack interactivity and are essentially static images.

Mockups add colour, typography, icons and other visual elements to give a realistic impression of how your app will look.


Once you approve the mockup, designers move on to creating high-fidelity prototypes.

Prototypes are interactive and functional simulations of your app. They enable you to experience how the app will work so that you can provide feedback on its usability.

Prototypes can include clickable elements, animations and even simulate user interactions to mimic your app's behaviour.

These stages of app design help ensure a systematic and iterative approach to creating user-friendly and visually appealing applications. They allow designers to collaborate, test concepts and refine the app's design before moving on to the development phase.

Why do you need app mockups?

Creating app mockups is essential for designing and developing an app for several reasons:

1 - Visualisation

Mockups provide a visual representation of the app's design, allowing you to see how the final product will look and feel.

2 - Feedback

Mockups facilitate early feedback from team members and users, helping identify design flaws and improvements before development.

3 - Communication

Mockups serve as a common reference point for designers, developers and clients, ensuring everyone is on the same page regarding the app's design.

4 - Iteration

Mockups enable iterative design, allowing designers to refine and adjust the app's appearance until it meets expectations.

5 - User Experience

By visualising the user interface, mockups help designers optimise the user experience and ensure usability.

6 - Cost effectiveness

Detecting design issues early through mockups saves time and money by preventing costly changes during development.

7 - Decision making

Mockups aid decision-making processes, helping you make informed choices about the app's design direction.

Overall, app mockups are crucial in the design process, enhancing collaboration, reducing risks and ensuring a successful app development journey.

What do app mockups include?

App mockups typically contain many elements so that they can provide complete visualisation:

1 - Layout

Mockups show the arrangement of the app's screens and elements, providing an overview of its structure and navigation flow.

2 - User interface (UI) elements

They help depict visual representations of buttons, icons, menus, forms and other interactive components that make up the app's interface.

3 - Colours and typography

App mockups include the chosen colour scheme and font styles that define the app's visual aesthetics.

4 - Content placement

Mockups exhibit the placeholder content, showcasing how text, images and multimedia will be displayed within the app.

5 - Screen transitions

They contain visual cues or annotations indicating how users will move between screens and interact with the app.

6 - Interaction states

They show the different states of UI elements, such as active, inactive or selected, to demonstrate their behaviour.

7 - Branding elements

They focus on logos and branding elements that maintain consistency with the app's overall brand identity.

8 - Annotations and notes

They contain explanatory notes and comments for designers, developers and stakeholders, providing context and guidance.

Best practices for designing app mockups

By now, you know that creating app mockups is a crucial step in the app design process. Here are some best practices to ensure you create effective and impactful mockups:

1 - User-centric design

You should always prioritise user experience, keeping your end-users in mind and making the app intuitive, easy to navigate and visually appealing.

2 - Start with low-fidelity

Begin with low-fidelity wireframes to focus on layout, content placement and user flow before diving into detailed mockups.

3 - Consistency is key

Maintain consistency in colours, typography and UI elements throughout the mockup to create a cohesive and professional look.

4 - Mobile-first approach

Design for mobile devices first, as these days most apps are used on smartphones. Optimise for different screen sizes, orientations and operating systems.

5 - Realistic content

Whenever possible, use real content or realistic placeholder content to get a more accurate representation of the app's final appearance.

6 - Whitespace and simplicity

Embrace whitespace to create a clean and uncluttered design. You should keep the interface simple, avoiding unnecessary elements.

7 - Interactive elements

If possible, add interactive elements or create clickable prototypes to demonstrate user interactions and simulate the app's flow.

8 - Feedback and collaboration

Share mockups with clients, team members and potential users to gather feedback and collaborate on improvements.

9 - Iterative design

Embrace an iterative approach, making necessary adjustments based on feedback, usability testing and evolving project requirements.

10 - Stay updated on trends

Keep up with current design trends, UI patterns and best practices to ensure your mockups are modern and engaging.

11 - Focus on app goals

Align the mockup with the app's objectives, ensuring that every design choice serves a purpose and contributes to achieving those goals.

By following these best practices, you can create app mockups that effectively communicate your design ideas, facilitate collaboration and lead to the development of user-friendly and visually appealing apps.
