The importance of mobile UX design

Do you have a great idea for your mobile app? That’s perfect! But even the most innovative idea won’t guarantee success if you don’t put your target end-users and their needs at the centre of all your efforts.

So, how can you make sure mobile app users will keep returning to your app instead of rushing toward your competitors? A flawless user experience is the answer!

This comprehensive guide will tell you everything you need to know about mobile UX design. We’ll walk through best design practices and identify the business benefits of providing a seamless experience for mobile users.

But first…

What is mobile user experience (UX) design?

Simply put, mobile UX (User Experience) design is the process of creating a seamless and meaningful experience for people using a mobile device or a wearable. With this approach in mind, designers strive to meet users’ needs, requirements and expectations toward mobile digital solutions, mostly applications. Here, the main focus is to make mobile apps or websites displayed on phones as accessible, valuable and usable as possible.

Importantly, you need to keep in mind that UX design differs slightly from mobile UI design, and these terms can’t be used interchangeably. While UI design concentrates solely on the surface of the mobile product, UX design goes far beyond just visual presentation. For that reason, the UX design process includes steps like user testing, market and competitive analysis, as well as user research (including the analysis of user behaviour).

What’s the business value of UX design for mobile apps?

Currently, there are 1.96 million apps available at your fingertips in the Apple App Store and 2.87 million apps in the Google App Store. These numbers speak for themselves and prove that it’s extremely challenging to stand out from the crowd and outperform the competition.

In such a highly competitive environment, users have a wide selection of mobile apps to choose from. And as you can easily guess, they will opt for the best ones. It leads to one conclusion: only by providing a valuable and seamless user experience can you convert users into fans of your app.

Mobile user experience design may bring some satisfying business benefits, such as:

  • A large number of app downloads
  • Positive user app ratings and reviews
  • Considerably higher mobile app retention rate
  • More in-app conversions
  • High revenue
  • Investing money in only the most necessary app features
  • Gaining extensive knowledge about your target audience

As you can see, good mobile UX design is not there just for its own sake but can help you elevate your business to a whole new level.

What are the differences between desktop and mobile UX design?

Does it even matter if you’re building your digital solution for a desktop or a mobile phone? It definitely does!

Just think about it: do you use desktop and mobile apps in exactly the same way? Or maybe they differ somehow in terms of content organisation or menu presentation? I’m sure you’ve noticed that the differences are quite substantial.

The main differences between desktop and mobile app UX design come down to:

Screen size

As desktops have much larger screens than mobile devices, they can include comparatively more extensive sections, and they will still look pretty good and legible. With mobile UX, things are a bit more complicated.

Application on both mobile and desktop devices

When designing an application or a website tailored to a mobile device, you need to include only the most essential information. Make a proper selection and consider which sections are necessary and which ones can be omitted. After all, you have only 4 or 5 inches at your disposal, so make good use of them.

Content organisation

Different screen sizes affect the way content is organised. Since desktops are much larger and have more screen space, they give designers more flexibility in building layouts. Here, designers can place content in multiple columns, and the user still won’t experience any significant difficulties finding all the necessary information.

On the other hand, mobile design requires long scrolling if we want to include several long sections. So you don’t have to squeeze everything above the fold. That would cause an unnatural visual effect and makes the content illegible.

So don’t be afraid to use long scrolling in your mobile digital solution. It turns out that users are willing to start scrolling if the content page encourages them to do so. According to MOVR, ​​half of users start scrolling within 10 seconds, and 90% within 14 seconds.


Another design distinction between desktop UX design and mobile UX design is menu formatting. You can freely place an extensive menu on desktops with numerous categories or even subcategories. Just like we did on our website:

Our menu displayed on desktop

Users who reach the website from desktop devices can easily read the text from all the categories and click the links without hassle.

However, creating a layout for mobile sites is an entirely different story. Here, users don’t select a category in the menu using the cursor but by tapping with their fingers. And since our thumbs are relatively larger, menus on mobile devices need to have much more space. For that reason, single-level menus are a much more prevalent solution in mobile UX design.

5 best practices in mobile UX design

You’ve learned what great mobile UX design is, why it’s so important from a business perspective, and we’ve also talked about how different devices require different design approaches.

Now it’s time to put the theory into practice and discover the best strategies to make excellent mobile app design. You’ll deliver an outstanding and hassle-free mobile app user experience to your users by following them.

1. Make it fully accessible

App accessibility is the practice of creating digital products in which no user experiences exclusion and can access the product practically at any time. Therefore, you must also include users with various permanent or temporary impairments when creating a mobile product.

Importantly, accessibility is no longer merely suggested for business owners but has become legally regulated. Official Web Content Accessibility Guidelines (WCAG) state that every web content must be perceivable, operable, understandable, and robust.

WCAG 2.0 principles: robust, perceivable, understandable and operable

To make the mobile product as accessible as possible, you need to follow these rules:

  • Make a clear distinction between foreground and background colours.
  • Avoid introducing fast-changing colours and other visual effects that may cause seizures.
  • Provide captions to videos and introduce text-to-speech functions or audio descriptions.
  • Make the essential layout elements easily adjustable.

These are only examples of how to make a digital product more accessible. Visit the official website of WCAG for more detailed guidelines.

2. Simplify the navigation

One rule always applies to navigation: there’s no need to reinvent the wheel. Trying to use revolutionary and therefore unintuitive solutions can confuse and irritate the user. And that’s not your intention, right?

When designing your navigation, consider the following rules:

  • Use common navigation patterns like the hamburger menu.
  • Choose easily recognisable icons such as home for the home screen.
  • Make sure all the sections are easy to reach.
  • Make the navigation visible.
  • Prioritise the options you place in the main menu.

With all that information in mind, try to simplify navigation as much as possible and use standard and well-known design patterns. That’s always the key to success!

3. Always put users at the centre

This rule applies to any type of design, not just mobile digital products. So, you should remember once and for all: when creating a mobile app or a website, you need to always concentrate on your users’ needs and expectations, and do whatever it takes to make their experience as pleasant and relevant as possible.

And how do you get to know your potential users better? How to discover what irritates them or causes problems? By conducting thorough user research.

During this process, you will not only examine users but also analyse the market and competitors. By applying different qualitative and quantitative methods, you will be able to gather user feedback to use in the further steps of the design process.

4. Consider mobile design constraints

As we have already explained, designing for desktops and mobile devices differs in many ways. And one of the most impactful differences is that mobiles face far more limitations. They result from the considerably smaller screens, the possibility to display a single window at a time or even storage capacity.

This is why when creating a user-friendly mobile solution, you need to consider all the constraints that may disrupt a smooth experience.

5. Make the content legible

Want to engage your users and make sure they keep consuming your content? You need to make sure that your text is legible. Experience the power of UX writing for yourself.

When it comes to typography, follow these simple rules:

  • Always choose fonts that will go well with different sizes and weights.
  • Use adequate contrast between the text colour and the background colour.
  • Avoid small text size – below 11 points, the text becomes practically illegible on a mobile screen and may cause eye strain.

Improve UX for mobile devices today!

Offering users a “nice” or “good enough” interface will not win them over and meet their expectations. You need to make sure that their entire experience and every interaction with your mobile solution is flawless, hassle-free and relevant. Therefore, choosing the right user experience design agency is crucial to the development of your unique digital products.

Here, we have collected some good practices that may improve your mobile UX design. However, remember that this process is far more complex, and every digital solution needs a custom approach.
