UX vs UI
It looks a similar little bit. It is confusing if you don't fully understand what it is.
UX stands for User Experience and UI stands for User Interface. So, what is the job for UX and UI Designer?
They focus on the user's journey. They focus on how user's process to problem, solution, interest, needs, etc. They need to understand all about it to make user easy to solve their problem and to get what they need faster and better.
They focus on the product. They focus on the instrument, visual, typography, etc. They need to make the product is easy to understand and easy to use.
In the website or application design. UX is about the layout, flow, etc. UI is about typography, icons, etc.
