A well-designed User Interface and User Experience draw the attention of target audiences toward a mobile app.

As per a study by Forrester, good UI can raise the conversion rate of a website by 200% and UX design by 400%.

Around 90% of smartphone users’ time is spent on Mobile Apps as per Insider Intelligence and 90% of users will leave a site solely based on the bad design as per Finances Online.

Designing a mobile app interface is not restricted to just creating a few eye-catching designs or making navigation straightforward, it works with the aim to improve user interaction and solve what they are looking for through a mobile app layout design.

While it has been established how the success of your app relies on how well and efficiently you design mobile app UI, let us dive into the concept further.

What is User Interface Design for Mobile Apps?

The mobile user interface or mobile app interface design is what you see when you use an application. Mobile app UI consists of the visual representation, interface, navigation, and processes that work behind the functional and structural actions in the mobile app.

The importance of mobile app interface design and user experience (UX) go hand in hand. UX is the holistic appearance and function of the app, while UI is all of the interaction in the application. In short, an app that is appealing and most feasible to users is an outcome of efficient user experience and user interface design techniques involved in building an app.

Types of User Interfaces for Mobile Apps

The most important thing to remember is that not all mobile UI designs are identical. They vary from brand to brand and on platforms they get live on.

Each screen you see on your mobile app has a different meaning and processing rules to enhance the user experience. Here are different types of mobile UI patterns that you must know.

1. Splash Screen

Splash Screen UI Design

The first screen you see on the launch of any app that shows the name of the app is the splash screen. It is used as a way to conceal the processing time and help the user know that the app is being prepared in the back. In addition, some apps come with illustrations, headlines, or a loading pop-up message/moving dot to keep the users engaged and interested in the app.

2. Onboarding Screen

Onboarding Screen UI Design

These screens help first-time users understand the app’s main features, which tell them about the app’s next steps, essential elements, and functionality and make the user journey less complicated.

3. Home Screen

Home Screen UI Design

The main screen of the entire app. All other screens are linked to the home page as it highlights the functional menu and features. Ideally, the icons on the home screen mustn’t merge and should be visible and in a designated place.

4. Login and Profile Screens

Login and Profile Screens UI Design

Most apps have a login ID before you start using them. The right UI design of a login screen must clear all unnecessary distractions and make the experience quick, interactive, and smooth. The profile screen, on the other hand, holds all your information and progress and must provide customization to the fullest.

5. App Screens

Importance of Mobile App UI Design

1. Saves time and cost in the long run

By keeping the critical user interface design guidelines for mobile applications in mind, you will be able to save the time and cost that would go behind revamping the app again and again. Furthermore, the initial time investment in Android user interface design or iOS app user interface design can lessen challenges during and after the launch.

2. Attract and retain loyal customers

Good UI grabs the attention of the user and makes sure they stay. Having an intuitive UI can make users stick around and come back many times and recommend the app to others too.

3. Helps build a brand

The purpose of a good UI is to make the content engaging and navigation less complicated. It helps the user understand the app flow easily, thus increasing satisfaction, and ultimately building a good market value and surpassing the competition.

4. Assists with getting the app featured in app stores

An excellent mobile app design is determined by how many users like it. With a good UI/UX, getting good ratings and reviews from satisfied users becomes easy, which in turn,  brings the mobile app to the top lists of any category while pushing more traction toward your app.
