What tools or principles can I use to design a good user interface (UI)

Answer 1

Diego Durán Aja , the principles you might want to follow are clarity, accessibility and consistency across components and interactions. This helps users navigate intuitively thereby making the communication of the UI is inclusive and effective.

Some or platforms preferred by front-end designers for creating wireframes and interractive prototypes are Figma, Sketch and Adobe XD. You might also want to use Tailwind CSS or Ant Design to create a good UI.
Lastly, you can use testing tools like UserTesting to optimise your UI design.
Following the Web Content Accessibility Guidelines (WCAG) is also pretty useful.

Good luck! Hope this helps!

1. Tools for UI Design

- Figma

- Balsamiq
- Canva

2. Principle

- Consistency: keep layout, fonts, colors & button styles consistent across screens.
- Clarity (creativity): a user should immediately know what to click and where they are.
- Feedback: use hover states, loading indicators & confirmations.
- Hierarchy & spacing: use size, color & spacing to show importance.
- Mobile-first: the majority of users interact via phones today

In one of our projects (a food delivery app for a regional brand), we designed the home screen with only three buttons: Order Now, Track Order & Offers. The simplicity boosted user retention by 40% because even first-time users could instantly understand what to do.
