User testing is integral to a good mobile application design but how does one come to the best design in the first place? Simple, a UI design tool is the answer as it allows a designer to create interactive prototypes. After all, getting things right at the drawing board means improved user testing and user experience. Sunflower Lab has asked its UI/UX designers their opinion on popular UI design tools. From their decade of experience here’s their take on how to smoothen the entire design process.

User experience is an important benchmark when it comes to gauging the success or failure of a product or application. And it is User Interface (UI) that defines the design of mobile applications and websites. Just factor in what you appreciate in a mobile application yourself. The visual appeal, modes of interaction and foresight applied is a blend of both technology as well as creativity made easy through interactive prototypes used in the development stage.

And UI isn’t just about making a user more comfortable, but also about how this comfort indirectly translates into making an application or software more popular by:

  • Positive user experience which brings in more customers.
  • Users with a good experience tend to remain brand loyal, especially if they find less of a learning curve.
  • Customer support related expenditure is less.
  • A ratio of a higher rate of customer satisfaction

However, with there being so many UI design tools available, it makes sense to have a handy list of those that are expert certified as the best UI design tools. Below we explore what UI design is and the UI design tools available in more detail.

What is User Interface Design?

At its most basic, UI design is the overall look of a particular website or a mobile app. UI Design contains Typography, Colors, Visual Hierarchy, Visual Design and the use of interactive prototypes.

Usually, UI designers design mobile apps, websites, or digital assets which will be part of digital media. UI Designers need to be up to date with the latest design trends, and current tools and therefore, must be familiar with the recent tools and technologies as well as user interface design tool. However, technology does not reign supreme here as creativity is the main skill, hence, a UI Designer can fix real problems by means of creative ideas.

Of course, user testing is an integral part of the process, but until an outline or map isn’t created, testing is rather at the end of the cycle.

Captured below are the top tools UI Designers using and based on this survey, please check the below image for more details:

What a UI Designer Brings to the Plate

A user interface designer is responsible for the white space, visual hierarchy, and colors of the website or app. Furthermore, contrast ratio for better usability and readability also has to be factored in. A UI/UX designer also brings the application to life through iconography, illustration/vectors, and the device’s responsiveness of the interfaces designed.
