User Experience with Mobile Apps

With a massive 204 billion apps downloaded in 2019, it’s never been more important to ensure your mobile app UX design stands out from the crowd. After all, mobile apps have higher engagement rates than traditional desktop use, and the Millennial market spends almost four hours a day browsing on their mobile devices.

But what is the elusive X Factor (or should that be UX Factor?) for making mobile-first web design a hit with users? Let’s take a look at some of the magical ingredients mobile app developers (like us) have up our sleeves for creating enjoyable on-the-go interactive experiences.

What is mobile UX?

Mobile UX is designing a user experience that is optimised for hand-held or wearable devices. You need to consider best practice for mobile usability including how to:

  • make the best use of smaller screens
  • cater to fingertip-friendly navigation
  • deliver fast results with minimal effort

Good UX equals user satisfaction but it’s not as simple as creating a miniature version of your website. To borrow a phrase coined by Nokia, the key takeaway is ‘Don’t shrink, rethink’. When we’re re-thinking for mobile-first web design, we like to consider this quote from Apple co-founder, Steve Jobs: 

“Design is not just what it looks like and feels like. Design is how it works.”

In other words, the look and feel of the mobile design is equally as important as the app’s functionality, which must be tailored towards the smaller screen. Which neatly brings us on to…

User experience

What are the essential features of mobile app design?

For us, the three pillars of successful mobile app design are:

  • Simplicity
  • Navigation
  • Visual design


The mobile app design and interface should be easy-to-follow, clean, and intuitive. As 94% of mobile users use portrait mode, there’s limited width to play with so use your real estate wisely. To help people complete tasks with as few steps as possible, only include what’s needed for the user journey. This means they’re less likely to get bored or lost in your app. A good rule of thumb is to only include one call to action per screen.  


The user journey is all about the flow. To keep it moving forward everything should follow a logical structure that’s easy to navigate. If it’s not self-evident with minimal interaction, the risk is the user will spend time trying to work out how to navigate your app rather than concentrating on what you want them to concentrate on: your content. So consider quick and easy solutions to their needs and leave everything else out.  

Visual design

The screen size is limited, there’s screen glare, plus people often use mobile devices whilst multi-tasking. But the good news is there are design tricks you can employ to create an eye-catching app. The first is colour which research has shown can affect behaviour and be attention-grabbing. In fact, that’s why The Simpsons are yellow. Matt Groening told the BBC

“When you’re flicking through channels with your remote control, and a flash of yellow goes by, you’ll know you’re watching The Simpsons.”

The second visual trick is to ensure your typography and font size are legible. Apple recommends a minimum Body text size of 17pt and consistent use of font between platforms will also help reinforce your brand identity.

Our tips for better mobile app design

We’ve been doing this since 2004 (which is about 400 years in fast-evolving technology years!) so truly understand how to elevate your mobile app project and leave a good first impression about your app and your brand. Here are a few small tips that will make a big difference to your users. 

User experience

Consider user needs

It can be tempting to overload your app with multiple features to try and grab the user’s attention, but this scattershot approach can often have the opposite effect. Instead, consider their needs and the purpose of the app. It’s fine to start planning the mobile UX development lifecycle with a broad brush as long as you trim back with each new pass. Simplify your app’s navigation as much as possible and eliminate nice-to-haves in favour of must-haves. Each tap (or swipe) should take your user one step closer to completing their goal.


When space is of a premium, icons are your best friend. Attention spans can be short in mobile UX and icons are a great shortcut to helping the user navigate through your app, explain a task, or simply make your app look less cluttered. After all, if a picture paints a thousand words, an icon can certainly take the place of a paragraph or two.

Easy searching

Designed for use anytime, anywhere, your mobile app should give the user a quick and easy route to discovering what they need with the minimum number of actions possible. This can include filtered searching, keyword searching, and barcode scanning.

All aboard

Onboarding is a vital component of attracting and retaining users. So adding features such as a ‘How the app works’ tutorial and multiple sign-up options will make a good first impression and help improve conversion rates.

Push notifications

There’s a fine line between annoying and enhancing, so use push notifications wisely. Try to ensure they’re timely, relevant, and add value to the UX. If they’re unnecessary or complicated, leave them out.


If you’ve ever tried to complete a lengthy form on a mobile, you know that the tiny keyboard isn’t conducive to essay writing. So, where possible, replace typing for tapping with fingertip-friendly call to action buttons and employ one-direction scrolling. You could also consider voice-activated commands for hands-free navigation – the perfect solution for apps designed to be used whilst completing another task such as driving or cooking.

The right form for forms

A fiddly form can be the perfect excuse for a user to end their experience with an app. If a data field is unnecessary, leave it out (do you really need a user’s email address, home phone number and mobile number?) Minimise user interaction with data inputting by including default values based on common results, saving user data to refill forms later in the journey, and including geolocation and autocomplete technology.

User experience


Have you ever completed an action on a website only to wonder if it’s registered your input? Annoying, isn’t it? That’s why responding to a user’s input is vital – even if it’s a simple tick icon that appears once the user’s completed an action, or a progress indicator to track their journey. In a similar fashion, a loading icon can eliminate a user’s fears that the app has crashed or is frozen by acknowledging that the app is processing their request.

Permission requests can be a little off-putting – particularly if they’re the first thing a user experiences on an app. So unless the request is essential to allow the app to function properly, let the user experience the app for a while before seeking consent. That way they’re more likely to trust your app and see the value of connecting with it.

Seamless synchronisation

Synchronising across platforms not only ensures that there’s a consistent look, feel, and functionality, but it also allows the user to start their journey on desktop and continue it on a device. This can help boost conversion rates and turn a looker into a booker.

Pre-empt mistakes

Let’s face it, we all make mistakes. The secret to great mobile app design is to try and make those mistakes before your users do. By planning for the worst you can hopefully catch and rectify potential hiccups before your users even download the app.

Test, test and test again

A great-looking app means you’re halfway towards a great user experience. So don’t stop there. Testing the app’s ease-of-use and functionality is the only way to see if it works as well as it looks. If possible, let real users take the test drive for you as the fresh eyes can often spot things insiders miss. 

Post-launch, continue to monitor the analytics so you can make tweaks as required to ensure your app stays relevant and useful to the user. After all, a UX-friendly app constantly evolves. A non-UX-friendly app risks extinction.
