User interface designing is not mere art. Interfaces are a platform meant to serve a purpose, and their effectiveness can be gauged. However, the best mobile app UI designs are not just utilitarian; they inspire, communicate, evoke, deliver, connect, and intensify the relationship between users and the digital world.

Here are some of the key elements we live by here at Xecuit that truly good quality user interface is comprised of in today’s mobile app world.


Inspire Clarity

Clarity is the most fundamental requirement of any user interface. It ensures that people are able to understand what the interface is trying to convey and how to use it. Clarity is one of the key attributes that consumers use in setting their level of expectations for user experience. Without clarity, you have no credibility in the eyes of the user. One hundred clear screens is better than a single cluttered screen. Simplicity is key, but having everything housed on one page doesn’t always make things simpler to navigate. Dividing up content onto multiple sections, pages, or screens ensures a better first impression for your app’s users.

Enable Interaction

Every interface exists with the sole purpose of building a connection. Therefore, the user interface must be one that enables interactions. Simply having information on your app isn’t enough to be successful in the age where information is boundless. It must have a way in which users can interact with the app in some shape or form. Design each interaction a user has with your interface thoroughly with all desired steps connected for them to easily be guided through your app.

Conserve Attention

User attention is priceless in a world full of distractions, and great UI design is what commands and conserves our attention. Keeping your design focused on your end goal for the user with as little extra features and distractions is key to achieving your desired interaction between users and your app.

Grant Control

Let your users have control of the interface by showing them their status on a regular basis. By guiding them, you can get the user down the correct navigation channel by offering tips and insight at each step. Putting yourself in the end user’s shoes is essential for this. Think of any questions or concerns one might have using your app, and have the answers ready right when and where they arise.

Maintain Visual Hierarchy

Visual hierarchy gives a clear viewing order to be followed by users for the visual elements on a mobile app. When everything is of equal weight or importance, the end user gets lost or the feeling of information overload and ‘bounces’ from the app. This is why at Xecuit, we stress having, at the very least, primary and secondary information and action items.

An interface can have multiple secondary action items, but it is important to make sure they are in fact secondary. It should be clear to any user what is trying to be communicated with the most emphasis so they can fully grasp your prioritization. Other factors to consider within visual hierarchy are size, color, contrast, space, symmetry, and proximity.

Reduce Cognitive Load

When you group similar elements together in placement or orientation to depict a natural relationship, it gets easier for user to understand the meaning behind your interface. This strategy is called reducing cognitive load — making interpreting and using your app less of a guessing game.

Make Everything Intuitive

The user of your  mobile app UI design should be able to expect and understand how the interface will work just by looking at it. People are more comfortable with things that behave in a familiar fashion, so by following the other key elements, this should go hand in hand.

Make It So Good, It’s Invisible

Although this may sound counter-intuitive, the most well done, professional user interface designs to date are the ones that go unnoticed by end users. This is because the best mobile designs provide not simply exuberant styles and eye-catching beauty, but they emphasize the goals of the end user — to use your app in the easiest way possible focusing on their objectives and tasks.
