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

What is UI Design in a Mobile Application?

The abbreviation UI stands for User Interface. It is the way through which users can interact with any mobile apps. Mobile app user interface design 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 mobile app UI principles is to provide the best interaction possible.

What is UX Design in a Mobile Application?

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 mobile app UX principles is to turn customers into loyal customers by providing a positive experience to them. UX is responsible for a user’s 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 it must be the best.

What are the Deliverables of UI/UX App Design Development?

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 to get a clearer understanding of the role of mobile app UI/UX design in the mobile app design and development process.

A. UI deliverables

Mood boards

Mood boards are used for presenting innovative ideas in a way that everyone understands. 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 understands 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. The 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 effort 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.

Now that we have looked into what UI and UX stands for and what is the role of mobile app ui/ux design in the development process, let us move on to the importance of UI/UX design in delivering a bespoke product.

To answer the question, ‘What are the Benefits of User Interface and User Experience design?’, 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 in the case of UI/UX design for mobile apps. 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, the importance of a UI/UX design lies in the creation of 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 to 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 UX design is important.

Tips to Improve UI UX Design

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 the UI/UX development process then you don’t need tips for improvement. However, there’s no harm in going through some great tips, considering how the effect of UI/UX design can be long lasting.

Mobile App Best UI/UX Practices

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.

Consider platform specific designs

There is a stark difference in the iOS app UI design and Android app UI design. Likewise, considering the way both the platforms are designed at the device level, the iOS app UX design also varies from the Android app UX design. 

What is important is for you to understand both Material Design and Human Interface Design in addition to the elements that separate them from each other

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 development process focuses on so many elements at the same time that the entire user experience turns bad. If too much is going 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.

Have detailed understanding of your audience

After everything’s said and done, the only thing that can save the effect of ui/ux design from being negative is having an understanding of your users. Only by knowing who you are making the product for, you will be able to deliver a memorable experience to your user set and the world. One way to achieve that is through a well strategized product discovery workshop

The only thing left for you to do is find a trustworthy and reliable app design company to partner with. A proper app design and development company will help you expand your mobile ui ux design services.
