Top 5 Mobile UI Mock-Up Tools

By Neha Bharati, Community Contributor -

Any application has a blueprint before its product launch. Websites start with a basic mockup of how it should look and how the UI should turn out. Similarly, mobile applications also begin with a blueprint where the basic idea is mapped into a minimal UI mockup that gives an idea of how the application should look. This has several advantages, and many tools are available to mock the UI for mobile applications and eventually conduct visual testing

Let’s understand these top five mobile UI mockup tools or mobile app UI design tools and how they streamline the development of mobile applications.

What are UI Mockup tools?

Building neat mockups or wireframes for an application process is tedious unless you find the right mobile app design tools. These mockup tools or mobile UI design tools make it easy for designers to showcase their applications and give an idea of what they want to build.

Mockup tools are meant to help product designers develop a basic UI for the application that can help them explain the flow and functionality of the application. This is not an easy task to achieve conventionally. Mockup tools provide a range of built-in features, making it easy to build custom designs from scratch. There are other benefits of UI tools like

  • Providing a roadmap for mobile application development projects
  • Saving cost and effort to build a UI design from scratch
  • Accelerates feedback cycle since these tools help deliver fast mockups and leave more room for tweaking the app as required
  • With mockup tools, it is possible to make downloadable files compatible with any Android or iOS.
  • Some mockup tools are even password-protected, providing a secure platform for creating and testing app designs

Choosing a Good UI Mockup Tool

When investing in a UI mockup tool, consider these 5 key factors before committing to anything. 

  • Learning curve: Any tool can be widely used based on how easy it is to adopt it with its dynamic features. 
  • Collaboration: Design relies heavily on collaboration, so the mockup tool must make it easy to collaborate across teams 
  • Usage: Another point is how well it fits into your design process. For example, use sketch or Photoshop. The mockup tools should be able to import these files instead of separately exporting assets and then building everything from scratch 
  • Cost: It is important to choose a tool that fits our needs and consider whether it provides free basic features. There can be some niche features that are paid but it is up to the designer to opt for it or not.
  • Fidelity: depending on whether you need to mockup the application layout or some complex interactions, one can classify the project requirement as low, medium, or high fidelity. Low fidelity is when one wants to test an idea. Medium fidelity is when the focus is on layout, information, and interaction design. High fidelity is when the focus is on visual design, animation, and micro-interactions.

Closing Notes

There are so many mobile testing tools available in the market each with its features. Depending on the requirements of the design process, designers can choose the tool suitable for them. 

Designing mockups is an inevitable part of any mobile appl, and mockup tools make it possible to move from paper for prototyping to making neat, functional complex designs. These mockups also can be used for beginners and experienced designers too. The future of visual comparison testing relies on enhancing these tools for effective UX and UI design.

  • Once the mobile UI mockups are validated, and the app is developed, you should test it to determine if its features and functionalities work as expected.
  • Conduct manual and automated testing using BrowserStack App Live and BrowserStack App Automate.
