3 free mobile mockup templates to download plus Justinmind’s top tips for designing your own mobile app mockup

Designing a mobile app mockup is the best way to visualize how your app will look and feel when complete. Mockup templates are an essential part of the design process, helping you:

  • Set design priorities and gauge feasibility of client requests
  • Define and iterate on information hierarchy, navigation flow and interaction
  • Facilitate communication between product teams, providing visual design specifications of what needs to be coded
  • Test logic and fine-tune designs based on target user feedback

…the list goes on. That’s why mockups, along with wireframes and prototypes, are the most popular type of deliverable among UXers. Luckily, there are plenty of design tools out there (such as Justinmind!) to help you create awesome mockups.

Now that you know how great mobile app mockups can be, you’ll probably want to try building your own. But first, let’s take a look at some dos and don’ts of mobile app mockup design. Plus, check out three Justinmind mobile app templates for you to download, free!

3 top tips for your first mobile app mockup

Make your mobile app mockup usable

Your primary concern throughout the mobile design process should be your users. Users need to know exactly how to work your app, because if they get lost, they may close the app never to return.

That’s why designers build functional app mockups with built-in mobile gestures that target users can interact with. Upon completion of the first mobile app mockup iteration, users will be able to test out and give feedback on the app’s navigation flow and touch UI elements. This will allow you to make your app mockup as accessible and inclusive as possible.

It goes without saying that both sites and apps should be usable. But when designing a mobile app mockup, you’ll also need to think about accommodating smaller screens (e.g. appropriate use of UI colors, whitespace and touch elements) – read more on small screen design here.

Give your users visual cues

Defining and testing out mobile gestures with your target audience is a good way to keep them in the loop. But what about when the user needs more guidance?

Whether they’re waiting for a page to load, refreshing their email inbox or filling in a form, micro-interactions, your mobile app mockup needs to give the user feedback on their interaction. How?  With micro-interactions.


These miniature interactions take place upon a user’s interaction with an app, and offer visual and actionable cues on what’s coming. Though only engaging the user for an instant, they provide a more complete picture of the state of the user’s request. Learn how to add them to your mobile app mockup here.

Use the right mobile UI pattern

Every user touchpoint in your mobile app relies on your mobile UI pattern, or navigation pattern. The wrong pattern will make it more difficult for your users to get from Point A to B, cause them frustration and diminish the user experience.

Users don’t respond well to change – so keep things familiar or you’ll quickly lose them.

“People tend to be unaware of an app’s navigation until it doesn’t meet their expectations.” Human Interface Guidelines for iOS

When mocking up a mobile app, it’s important to use a mobile pattern that users are comfortable with. This will help to ensure that their experience is as seamless as possible.

Additionally, make sure that your mobile pattern is in sync with your operating system (Android or iOS). For instance, both Android and iOS use tabbed bottom bars. But whilst Android uses the Overflow menu for additional settings, Apple and iOS use the More Options menu.

Mistakes rookie designers make with mobile app mockups

No matter what kind of mobile app mockup you’re designing, a good designer won’t deviate from design standards or principles. Here are a couple of bad design habits to avoid when approaching the mockup phase:

Skimping on the onboarding process

Every mobile app needs to offer their new users an onboarding experience. Onboarding helps introduce new users to the app, walk them through features and set up their online account.

Keep onboarding short, focused and interactive to avoid cognitive load. Successful onboarding can help improve user retention and engagement – more on this here.

Not setting defaults

Apps with great UX are those that save users time and effort. Mobile users are often on the go, and don’t have the time or patience to be asked for the same information twice. Default values and placeholders – such as suggestions in sign up form input fields and recent places in map apps – can be a big help.

Learn how to add placeholders to your mobile app mockups here.

But what’s even more important than design pitfalls? Using the right tool to mock up your app! Justinmind allows you to mock up the visual and functional components of your mobile app and them test them with real users.
