I understand that a good design is a useful one. But the reason I ask for "beautiful" design is that I have a web app that I believe has a pretty good functional design, but it is relatively ugly. No customer is enchanted by it, making it harder to make them use it long enough to realize that the design is functional.
I am no designer. I was only capable of making it functional because I use the app myself and I listen to customers that validate that my design is more practical than competitors.
I am a solo founder, and I have no money to hire a good designer to make it beautiful and keep it functional. So I want some references to serve as inspiration so I can create a beautiful design myself. Thanks! :)
