There are many different ways to go about designing an app, but there are some specific things you can do to make sure the design is up to par with what user want. There are a set of global user interface engineering principles when used effectively reduces the job of the designer and creates a lively connection with the users who uses the app. Here are six common UI principles to build a mobile app with a seamless user interface design and experience:

1. The Structure Principle

This principle is based on the overall user interface architecture where there must be a purposeful organization of the design interface to make the user’s journey apparent and recognizable.

2. The Simplicity Principle

According to this principle, the app design should communicate clearly and simply in the user’s own language. It should offer the user meaningful shortcuts and thus reducing long procedures to perform a function.

3. The Visibility Principle

The design of the app should not have extraneous or redundant information because it can distract the user. The options and materials of the app should be highly visible but quick and simple as well.

4. The Feedback Principle

The design should keep users informed of actions or interpretations, changes of state or condition, and errors or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to the users.

5. The Tolerance Principle

The design should be flexible and tolerant, reducing the number of mistakes and misuse by allowing users to easily undo and redo. You should be able to do this while also preventing errors wherever possible by tolerating varied inputs and sequences and by interpreting all reasonable actions.

6. The Reuse Principle

The design should reuse internal and external components and behaviors, maintaining consistency with purpose rather than merely arbitrary consistency, thus reducing the need for users to rethink and remember.

3 Common User Interface Design Screens Used Globally

Technology firms build mobile apps based on their client’s requirements and business needs. There are a bunch of common screens that are applicable to all types of mobile apps.

1. Splash Screen

The first impression of a mobile app will be the key determinator as to whether or not a user will continue using it. The splash screen is the first image that the user sees when they finish downloading the mobile app. They are minimalistic and has a name, logo, or slogan of the product/business. To ensure elegance on different devices, designers focus more on making this intuitive and attractive. Splash screens are recommended to be shown no longer than 3-8 seconds otherwise it annoys the users.

2. Onboarding Tutorial Screens

These screens illustrate the navigations, flow and the benefits of using the app to the respective users. These screens appear when the users launch the app for the first time to get them oriented with the unfamiliar features and controls of the app.

3. Log-in and Profile Screens
