5 Mobile UI Design Rules That You Must Follow

The use of applications and their impact on people's lives is increasing at an exponential rate. 

More than 28% of the world's population used a smartphone in 2016. According to mobile statistics, the number of mobile device users worldwide is predicted to reach 6.1 billion by 2020. Hence, there is a huge transformation in the app industry. For example, today we have multiple types of apps that are being designed and developed everyday. And, that's not it! 

Since they are instantly available at any time and from any location, smartphones have become a go-to source for all kinds of information. Services and features such as banking, placing orders, healthcare tracking, and even home security has become part of the smartphone experience, in addition to communication and information collecting.

But it takes more than beautiful looks to provide a functional and engaging mobile experience. To elicit favorable responses, you must adhere to the basic mobile UI design rules. So, what are the top UI design rules that you must follow to ensure a good user experience for your app? Keep reading on!

Learnability is the ease with which new users can accomplish fundamental activities.

Efficiency refers to how quickly people can do fundamental activities after learning the design.

Memorability refers to a user's ability to recall how to utilize a system.

Errors The number and severity of errors made by users, as well as the ease with which they may be corrected.

Satisfaction refers to how enjoyable it was to use the design.

Now, with that being said, here are ten tried-and-true mobile UI design rules for generating outstanding mobile user experiences.

Content Prioritization

The attention span of humans is quite limited. I mean, it's really, really brief. To be precise, 8 seconds. As a result, capturing your consumers' attention during the initial few seconds of engagement with your products is critical.

Less is more in this case. Keep the number of interface components in your goods to a bare minimum while creating them. Users are more engaged and comfortable with items when they have simple designs.

Display only the material and features that the user needs. Because of the limited space on a small screen, every additional element you add will overwhelm your users. A menu should be used to access secondary material.

Make Navigation Easier 

The capacity of your design to be learned is critical to its success. Users should be able to navigate around your program using clear paths and perform all key activities without the need for any explanations.

Users lack the patience to struggle through several processes to achieve their goals. If learning how to navigate around your product takes too long or requires too much work, you're likely to lose customers.

User journeys should be designed in such a way that a job can be completed in a single app. Allow consumers to do tasks without having to switch between sites and apps. Simplify the procedure by having all of the necessary information on hand.

The user should constantly know where they are in your app, without having to wonder how they got there or what they should do next.

Sizes of Touchscreen Targets

People use their fingers, and maybe their toes, to interact with touch displays, but that's none of our concern. Making interface components large enough to capture these actions is crucial. But how large can they get with such a tiny quantity of screen real estate?

When using their cellphones, people use their thumbs more than any other finger. Small touch targets can be aggravating since they need more precision and are more susceptible to mistakes. The iPhone Human Interface Guidelines recommend a goal size of 44 pixels wide by 44 pixels height as a minimum. Microsoft recommends a touch target size of 9mm/34px with a minimum touch target size of s in the Windows Phone UI Design and Interaction Guide.

The size of the target is significant, but so is the distance between them. If action buttons are too close together, the user may take unintended actions, resulting in irritation. To avoid problems, it's especially necessary to space apart conflicting action buttons, such as the save and delete buttons.

At the end of the day, even when goal size and spacing are scaled correctly, we're all human and make mistakes. As a result, incorporating an undo button in your designs will help many people (including yourself) avoid making mistakes.

Provide User Control

People like to believe that they have control over their activities. So that's what you're going to have to offer them.

Allow people to customize their experiences by allowing them to make selections. The user has control over the system by changing settings, managing notifications, and canceling actions. Apps can provide suggestions or issue cautions, but they should not make decisions for you.

Let the user know what's going on when they need to know! Integrate status and other forms of feedback without interfering with the user's workflow. If an app needs registration, let them try it out first or continue as a guest to get a feel for it before committing. 

The ultimate objective of developing online experiences is to provide a seamless experience across all devices. But saying it is easier than doing it.

Ensure Seamless User Experience

Effortless events go unnoticed. The user is unaware of it, yet the flow is a natural process that seems "correct" to them. Users today want to see mobile designs that are functional, adaptable, and responsive. Reduce interaction time by decreasing friction, eliminating steps and page loads, and focusing on essential user goals.

Reduce interaction time by decreasing friction, eliminating steps and page loads, and focusing on essential user goals. Make material available even if you don't have access to the internet, and give alternate routes to avoid dead ends. Make use of the phone's functions, such as the camera to scan barcodes, GPS to locate destinations, and touch ID to replace passcodes to make travels easier. Users like seamless interactions with designs and are pleased when their requirements are accomplished without difficulty.

For building seamless experiences, synchronization across devices is a top requirement. It gives consumers the impression that their workflow is not being disrupted, and that they are not being burdened by the need to transmit data. To build pleasurable and addicting experiences, go beyond fundamental usability characteristics. Communicate with your users to learn what they require and then provide it.


Designing mobile experiences must incorporate usability considerations in order to stay up with rapid technological developments and the move to smartphone use. Smartphone technologies are nearing their pinnacle of development, and consumers are intolerant of slow systems. The way forward is to provide amazing experiences for consumers to enjoy. And, the only way to ensure that the experience is good, mobile UI design rules must be followed with perfection.
