In today’s digital landscape, the significance of exceptional mobile user experience and intuitive user interface design cannot be overstated. With mobile devices becoming the primary gateway to digital interaction, designing interfaces that captivate, engage, and seamlessly guide users is imperative for success.

Today’s Designers and businesses must uncover the intricacies of mobile UX/UI design by delving into a curated list of dos and don’ts. From prioritizing user-centric approaches to avoiding common pitfalls, the list seeks to empower designers, developers, and businesses with actionable insights to create compelling, user-friendly mobile interfaces.

Dos of mobile UX/UI design

Prioritize user-centric design

Understanding your users is crucial. Conduct user research and create personas to represent different user groups. For instance, Airbnb extensively uses user personas to tailor their platform to various traveler preferences. They personalize recommendations, search results, and emails based on user behavior.

Responsive design

Create designs that adapt seamlessly to different screen sizes. Instagram is a prime example of maintaining consistent functionality across various devices. Its simple layout and scalable interface allow easy navigation and interaction on smartphones and tablets.

Intuitive navigation

Users expect familiar navigation patterns. Snapchat introduced swipe gestures for navigation, allowing users to move intuitively through the app. This simplified interaction has become a standard for many mobile apps.

Consistency

Consistency builds user trust and familiarity. Google’s Material Design is a prime example. It maintains consistent design principles across all its apps, creating a unified experience for users regardless of the app they use within the Google ecosystem.

Optimize load times

Speed matters. The mobile site redesign by Pinterest significantly decreased wait times, resulting in a 15% increase in SEO traffic and a 44% increase in user-generated ad revenue.

Thumb-friendly design

Considering thumb reach is crucial. Twitter’s mobile app strategically positions its main navigation bar at the bottom, easily reachable with one hand, enhancing the user experience for single-handed use.

Clear Call-to-Actions (CTAs)

Uber’s mobile app provides clear CTAs for users to request rides. Their prominent ‘Request Ride’ button with clear indicators makes it easy for users to take action, contributing to an intuitive user experience.

Visual Hierarchy

Prioritize essential elements through size, color, and placement. The Nike Training Club app uses bold typography and contrasting colors to highlight crucial features, guiding users through their fitness routines effortlessly.

Feedback and confirmation

Giving users immediate feedback is vital. LinkedIn’s ‘Connection Request, Sent’ notification assures users that their action was successful, providing reassurance and clarity.

Usability Testing and iteration

Continuously test and refine. Slack regularly gathers user feedback to enhance its interface, resulting in iterative improvements that align with user needs.

Navigating the challenges

The journey to crafting exceptional interfaces is as much about avoiding pitfalls as it is about implementing best practices. The landscape is riddled with potential stumbling blocks — missteps that can deter users, disrupt flows, and tarnish the overall mobile experience.

Since the mobile UI UX design world is ever-evolving, we must pay attention to missteps, or it could hinder user engagement and compromise the success of mobile applications and websites. In this data and AI-driven world, designers must be equipped with the foresight to sidestep these pitfalls and pave the way for a smoother, more user-friendly mobile design journey.

Don’ts of mobile UX/UI design

Overwhelming users with information

Avoid cluttering screens. Facebook streamlined its mobile app by simplifying its design and prioritizing key content, improving user engagement and retention.

Ignoring platform guidelines

Disregarding platform-specific guidelines can confuse users. The app ‘Foursquare’ initially faced criticism for ignoring iOS design principles, resulting in a redesign to align better with Apple’s guidelines and improve user experience.

Complex forms and inputs

Lengthy forms deter users. Booking.com reduced its form fields and introduced a visual progress indicator, resulting in a 3.5% increase in bookings.

Tiny or overcrowded touch targets

Accidental taps frustrate users. Spotify adjusted its mobile interface to have more significant touch targets, reducing the chance of misclicks and enhancing the overall user experience.

Intrusive pop-ups and ads

Disruptive ads hamper user experience. Forbes faced backlash for intrusive ad experiences, resulting in an ad-light version of their mobile site to enhance user satisfaction.

Ignoring accessibility

Inaccessibility alienates users. The redesign of the BBC Sport mobile app improved accessibility, adhering to WCAG guidelines, and consequently broadened its user base.

Auto-play multimedia

Unwanted auto-play disrupts user experience. Facebook revised its mobile app to allow users to control video autoplay settings, enhancing user control and reducing data consumption.

Unclear error handling

Vague error messages confuse users. Google’s mobile sign-in process provides clear error messages, guiding users on rectifying issues, resulting in a more user-friendly experience.

Excessive user permissions

Over-requesting permissions deter users. Over time, apps like WhatsApp have streamlined their permission requests, asking for access only when necessary, improving user trust.

Skipping User Testing

Not testing leads to overlooking crucial issues. Airbnb continuously tests its app with real users, enabling them to identify pain points and iteratively improve their platform.

Ignoring feedback

No matter how attached you are to your design, it can’t be set in stone. The design must be flexible enough for last-minute changes or revamps. Listening to what the user needs or demands might help you improve your UI UX design skills in the long run.

No dead-end pages

This one is for users needing help figuring out what to do after encountering a dead-end page. Ensure there are no blockers on the pages and there’s enough guidance for users to follow if they discover a dead-end page. Such pages affect consistency and rub users the wrong way.
