Mobile User Interface Design Principles for 2022

Content-first Approach

Content is the first element that should be prioritized to make the app design focused on the user. Following this approach emphasizes one to think in terms of context, problem, and the user. Regardless of which methodology you plan to use, with the content-first approach, you are bound to create a unified voice.

Tips

  • Use a visual approach to map the entire customer journey and keeping the larger picture in mind, use the content-first method.
  • A lot depends on which methodology you plan to use to develop your product. It would help if you prioritized which features will be launched first.

Fullscreen Size Matters

A few years ago, 16:9 was the popular choice of mobile screen aspect ratios, with a physical button underneath. But that trend changed and mobiles these days have 20:9 aspect ratios with virtual buttons.

Mobile apps have to adapt to this changing trend, with the flexibility to further evolve as per changing trends.

Ideally, the app should make the best use of the screen real estate available.

When designing graphics for a fullscreen mobile app, do not follow the age-old rule “one graphic size for all devices.” Although it reduces the time spent on developing the app, it is bound to fail when your users are accessing your apps from multiple devices.

Tips

  • Use visual hints and focus on micro-moments to guide the user to complete his journey.
  • Understand the importance of accessibility and try to include a dark-mode with your mobile app.

No Clutter

Clarity is an essential characteristic of an excellent mobile app design. A cluttered user interface (UI) has never yielded favorable results. Elements like too many buttons or images, only complicate usability, and irritate your customers. Say no to clutter and keep the design inconspicuous for improved visibility.

Tips

  • Use a minimalistic design approach to improve UI and only focus on maximum one or two actions on a single screen.
  • Avoid random content, keep the text concise, create headlines, and use white space wisely.

First Impression

Just like a homepage provides the first impression of a website, an app’s icon is the first thing visitors notice about it. A mobile app UI design should be able to entice users to download it. App icons have proven to be a significant factor behind the failure or success of an app.

Tips

  • Your mobile app will be competing against dozens, if not hundreds of other apps. We recommend using a unique symbol or shape as the app’s icon to make it instantly recognizable.
  • It is a good idea to give your app a small and catchy name.

User-focused 

One of the most critical mobile user interface design principles is empathizing with the user. It would help if you were well-versed with your target audience, have a clear understanding of their preferences, and create an app that caters to those preferences and also sets you apart from the competition.

Keep an account of all the demographic data through analytics. By empathizing with your customers, you can design an intuitive mobile app user interface that provides a solution to all of your customer’s pain points.

Tips

  • Conducting a survey among your target audience might help you to understand the user’s expectations from the app design.
  • While developing – integrating functionalities to solve customers’ pain points is a good idea. Moreover, always pay close attention to aesthetics.

Color Psychology

Add professionalism to your apps with subtle animations when transitioning between screens and pay close attention to the color schemes for your mobile app. Every color tells a different story and invokes a specific emotion. Pick those colors that align with your branding goals.

Tips

  • Pick the color palette that matches your organization’s colors as your mobile app should look like an extension of your website.
  • If the color of a button changes after a click, it signifies that a user action has been completed. Don’t forget to incorporate such subtle yet effective elements in the user interface (UI) of your mobile app.

High-resolution Images

Present day devices and faster internet connections can support high-resolution images. Deliver the perfect mobile app user experience with excellent imagery and boost engagement levels.

Tips

  • Improve your app’s visibility on more substantial screens with high-resolution images.
  • Using vector-based images is a good idea as they are useful and scale automatically with the screen resolution.
