The Essentials of Mobile App Design - Principles and Best Practices

The modern user's relationship with their phone is more intimate than ever. We dedicate a staggering 2 hours and 51 minutes to mobile apps every day and we expect a lot from these app experiences. Super-fast loading times, intuitive navigation, and maximum delight in each in-app interaction are all fundamental to user satisfaction and essential for app success.

So, how do you create apps that consistently deliver such fulfilling experiences?

This is where professional mobile app UI UX design solutions come into play. UI (User Interface) design focuses on the app’s visual elements and layout that users directly interact with, while UX (User Experience) design delves deeper, ensuring that every touchpoint feels effortless and enjoyable.

Professional designers combine the art of UI design with the subtler science of UX design to craft mobile applications that are not only visually stunning but also a pleasure to use. This is the magic that transforms a standard app into a ‘good app’, and a one-time downloader into a lifelong user.

Here we will discuss the core principles that guide the leading providers of mobile app UI UX design services. By applying these essentials of mobile app design, anyone can design apps that not only function flawlessly but also keep users coming back for more.

Minimize Cognitive Load

The true measure of an app's success lies in its ability to deliver effortless experiences. Users should be able to navigate and experience your app without needing to think. That is why minimizing cognitive load is a key principle of mobile app UI/UX design. Cognitive load is the amount of brainpower users have to apply to use an app. The lower this load, the more effortless and engaging their experiences. To create such a clean and intuitive UI that delivers effortless experiences, professional designers take various steps, including:

• Decluttering: Since designers do not have as much ‘real estate’ to work on with mobile devices as they do with desktops/laptops, cutting out the clutter is one of the main principles they follow. Every extra button, image, or icon makes the interface appear more complicated. So, pro designers eliminate every extra element in interfaces, that isn’t absolutely necessary.
• Minimalism: Since reducing clutter keeps mobile app users at ease, minimalism has become a bedrock of modern-day mobile app design. Most pro designers embrace a minimalist design approach that strives for simplicity and focuses only on essential app features and content.
• Intuitive Navigation: Implement intuitive in-app navigation patterns that your target users are likely to know already. For example, all app users know how swipe gestures, tab bars, hamburger menus, and other popular navigation patterns work. Including these familiar design features will help users navigate your app fluently.
• Break Complex Tasks Down: Breaking complex in-app tasks into manageable steps can instantly transform user frustration into accomplishment. For example, a lengthy payment process on an eCommerce app instantly feels more engaging when it is broken down into a series of clear, actionable steps. That is the power of dividing complex tasks into several less complex subtasks. It promotes clarity and drives user engagement.

Visual Hierarchy

A well-designed app can not only control users' attention, but it can also command and direct it. That is because well-designed apps always have a clear visual hierarchy: a clear visual order of design elements that subtly guides the users’ attention through the interface, drawing focus to the most important pieces of information. Here's how professional designers apply this order:

• Size and Proximity: Varying the size/proximity of design elements creates a sense of order. For example, larger design elements naturally draw more attention. Similarly, grouping certain elements establishes clear relationships between them and draws user attention.
• Color and Contrast: Contrasting colors can be used to highlight crucial interface elements. For example, using specific color combos consistently for navigation elements like menu icons or tab bars helps users visually connect the elements and better understand their functions.
• Typography: Designers carefully select the right size, weight, and style of font to ensure all the text in the app is easy to follow and understand. They also use headings and subheadings to improve the text’s readability further. This strategic use of fonts is called establishing a ‘typographic hierarchy’ and it is vital for ensuring smooth information flow.

Minimize Typing

Most people do not enjoy typing for too long on their small mobile screens. It’s a tiresome and error-prone process of collecting user input that can and should be minimized by designers. Here are a few practical ways designers can minimize typing:

• Keep sign-up and other forms as concise as possible; only ask for the bare minimum of info from users
• Use smart features like autocomplete
• Customize the keyboard design for the type of query being made. For example, when asking for the user’s phone number, present users with only a short numeric keyboard

A rule of thumb in UI design is that shorter is always better, especially regarding forms.

Maintain Design Consistency

Design consistency improves user familiarity which in turn eliminates confusion and fosters engagement. Make sure all visual elements (typefaces, buttons, etc.) and functional elements (interactive buttons) look and work similarly in all sections of your app. Respect Apple and Google’s design guidelines, and if you have a website, make sure it looks and feels just like your app.

A ‘great’ UI/UX design is a seamless combination of beauty, functionality, and constant improvement. So, treat your app’s design as an ever-evolving project and use user feedback to constantly refine the experience.
