Sometimes when designing a new project we get stuck and need a little inspiration. The problem I find is that all the design galleries are focused on websites, not web applications. Since marketing websites usually follow different design patterns, I don’t find them very helpful for inspiration on web app projects.
So here are a few of my favorite interfaces. Here I am mostly focused on aesthetics, but for some (Gumroad in particular) you should check out their user experience first hand.
YouVersion uses great simple typography to create a clean, focused interface. They don’t overwhelm the user with too many choices. In fact, they even have an icon-only navigation bar (you have to hover over the navigation to see the label).
