UX and UI are similar in many ways
CODE = skeleton
UX = organs
UI = appearance
Without solid bones, the whole body collapes and you can't use it
Without organs, the body can't function and it will die
Without a pleasant appearance, you will repulse or frighten others
„The combination of solid bones (code), healthy organs (UX) and a pleasant appearance (UI), creates a functional, meaningful and aesthetic organic machine (website or app).“
Surely you don't expect quality without any chemicals from a low-priced juice. The same applies to well-made products and services. Will you choose cheap substitutes or the real deal?
