Most of the people using digital media are either on mobile phones or desktops. Both platforms have the majority of digital users. Desktops are great for quick access to web pages and mobile phones are great to create engagement. We cannot stress enough on the popularity of mobiles and mobile related technologies, though. With this advancement, people are now looking to spend less time to get more done without having any issues to deal with.

Mobile applications are one of the biggest reasons why people are going mobile. In 2017, the number of app downloads was 197 billion and is said to reach 353 billion in the year 2021. People are rushing into mobile apps because of its functionality and the ability to get things done quickly. But what makes mobile apps better?

UI UX app design is one of the answers. The design of an app enhances the user experience which is the biggest factor that ensures the success of an app. Majority of users prefer an app that has simple yet elegant designs and has good performance. The UI UX design for mobile apps should not be such that it slows the performance of the app. This will result in a frustrated user eventually uninstalling the app.

To understand the importance of mobile app UI/UX design, let us understand both the terms well.

What is UI?

The abbreviation UI stands for User Interface. It is the way through which users can interact with any mobile apps. User interface design for mobile applications is aimed towards easy, enjoyable and effective interactions between users and the app. UI in IT is any device that allows users to interact with monitors, screens or mobile devices. The primary goal of UI is to provide the best interaction possible.

What is UX?

UX stands for User Experience. The whole idea of UX is to create a system that provides the best experience to the users. The aim of UX mobile app design is to turn customers into loyal customers by providing a positive experience to them. UX is responsible for a users journey through the mobile app or website which ultimately decides the success of the business.

Mobile app UI UX design is always put together as they are complementary to each other. For an app to be successful the UI UX app design must be the best.

What are the Deliverables of UI and UX?

The work of any UI/UX designer has many phases. During the UI and UX designing process, various deliverables are created for the clients. These deliverables are created for reasons like better communication with clients, documentation or presenting the ideas in a proper way. Both UI and UX have their separate deliverables, let’s take a look.

A. UI deliverables

Mood boards

Mood boards are used for presenting innovative ideas in a way that everyone understands it. It helps the clients understand the app idea that the designer will be working on.

Visual Designs

Visual designs will help understand the effects of elements in a design. The effects of elements like photography, typography, space, colours, layouts, images, etc. are better understood with visual designs.

Dynamic Prototyping

Another one of the UI deliverables is the dynamic prototypes. Prototypes help in improving the overall functioning of the app as well as making improvement as and when needed. With dynamic prototypes, UI can be built as per the clients’ desire.

B. UX deliverables

Competitive analysis report

The competitive analysis report is created to measure the level of competition your app has. All the efforts go into vain if the app is in a highly competitive market or if it is not prepared to beat the competitors. With a competitive analysis report, the strength and weakness of the competitor’s app can be found out.

User Personas

Designers have to make sure the client understand what their customers need and expect from the products. Creating a buyer persona not only helps in understanding customer behaviour but also in communicating the same to clients. UX process involves user research to learn the behavioural pattern.

User journeys, experience maps and user flows

Experience maps showcase users overall behaviour towards a product. The expectations, time spent, reactions, thoughts, needs, etc. are all displayed in the experience maps.

User journeys or user flows are specific steps taken by the user to interact at different stages of the product. These can be the current interactions or potential interaction with a product.

Interactive prototypes

Interactive prototyping is another one of the deliverables of UX. Rudimentary prototyping saves a lot of time and efforts and works well enough to get the job done. The prototypes help in demonstrating how the actual product will work once it’s fully developed. It also helps the designer communicate the ideas better.

Why UI/UX in Mobile Apps is Important?

To know the importance of mobile app UI/UX design is a must. Most developers create an app with great performance but fail to focus on the designing which leads to the downfall of the app. The balance between the functionality and UI UX design of an app is hard to keep but that’s what is needed to be done.

To answer the question, ‘Why UI/UX in mobile apps is important?’, let us look at the pointers below:

Attracts users

A saying goes, ‘A good teacher is the one that grabs and holds the attention of the students and then teaches the lessons.’. This saying is very apt for mobile app UI UX designs. The designs grab the attention of the users and ensure they spend as much time on the app as possible. However, the users should be able to understand the designs and navigation well enough to stick around for the long term.

Creates a good impression

For a startup or any small business, good UI UX is a way to create the first impression. When users visit your app, they should be hooked to it immediately so that they come back for it again and again. A good app has higher usage time and this can be done with the app’s UI UX design.

Get featured in app stores

Whether a mobile app is good or not is determined by how many users like it. The ratings and reviews by satisfied users will bring your mobile app at the top lists. To get your app featured in Play Store or App Store, make sure the users get a good UI UX. getting featured in the top lists of any category will automatically bring more traction to your app.

Get loyal customers

Attractive apps have more users and it’s a fact. Apps like Instagram, Facebook, Candy Crush, etc. have great UI/UX which has drawn millions of users to them. The satisfaction that comes from great user experience is what makes users loyal. Word of mouth is another reason why UI/UX in mobile apps is important.

Now that you have seen the importance of mobile app UI/UX design, let’s move further into the concept. It’s a common assumption that if you have mastered to design mobile app UX and UI then you don’t need tips for improvement. However, there’s no harm in going through some great tips for UI UX designing.

Tips to Improve the UI UX Design App

Use Conventional Elements

Using familiar elements in the app will save time for users. They can quickly learn the app without getting confused. Elements like buttons, icons, colors and symbols should be designed in the way it’s designed in most apps. The quicker users learn to operate the app, the higher will be the chances of liking the app.

Maintain Uniformity

It is very important for the design to be uniform across all the windows. The uniformity shows the quality of work put in the UI UX designing of the app. Not only with icons or buttons but the colors and patterns should also be the same across all media.

Employ the Right UI and UX designer

If you are focusing on the mobile app user interface design and experience then working with the experts is highly recommended. You can also outsource app development for your app from an expert app development agency to make sure the UI UX designs are on point. The UI UX designers should understand all the end-to-end user interaction and incorporate them within the app.

Make it as interactive as possible

An interactive app is better than a non-interactive one and that’s a fact. When you allow users to interact with the app, it creates a connection between them. Interactive apps give freedom to users to navigate themselves through different windows.

Don’t hamper the speed of the app

The speed of the app is just as important as the design. Startups do make this mistake by thinking the app only needs its appearance to attract users. But the truth is, the functioning of the app is just as important. The mobile app needs to be speed while having a good mobile application interface design.

Keep it simple and don’t complicate things

If a feature can be put in a simple way there is no need to overdo it. The users will appreciate the simplicity just as much as the overall app. Complicating designs leave app users either confused or furious and we don’t want either of those. It is also seen that apps with simple design have more users than complicated ones.

Keep the focus on limited things

Often the UI UX design of apps focuses on so many elements at the same time that the entire user experience turns bad. If too much is going on on the screen then that won’t let the user focus on the content of the app. Overcrowding content on the screen is another way to quickly lose users.

Google Home and Alexa have taken over the voice assistant world. These two technologies are being used by people to get anything and everything done.

Variable fonts

Fonts that will fit any writing space will have another place in the 2019 UI UX design trends. Earlier, inserting text in writing spaces had limitations to adjustment. It also made designers send multiple files for the font designs used. But variable fonts are a great solution for that as it only needs one file for any design.
