Just like learning to code, the best way to improve as a designer is to learn by doing. Still, that’s not to say that admiring and even copying (aka practicing) great work can’t do wonders. More than anything, seeing what other designers have done in the past can save you some serious time, because design has a history and everyone should learn from what works and what doesn’t.

And so, we’ve gathered this list of 15 gorgeous user interfaces (UIs) for your design inspiration. Note that designing a UI and evolving that into the perfect user experience (UX) are completely different things, but all fit together as a complete product.

1. 76 Synthesizer:

This is skeuomorphic design at its best, as the simulated textures actually help add clarity to how the app should be used. This serves in stark contrast to much of Apple’s skeuomorphic work, which generally serve as decoration and can end up being more distracting than anything else.

Being particularly experimental and risky, this concept app packs an interesting UI that takes the user through science fiction interfaces and combines them with facts and fiction on the subject.

7. Music Player App Concept:

This app concept changes the way you’d envision a music player should and could look on a mobile device. The use of space is certainly interesting, and while smaller controls like volume might be difficult to use while on the go, that particular function is resolved by the hardware.

8. Galeria:

This guy deserves a medal simply for trying to turn the classic music box into a full blown app. The fact that he actually appears to have been successful doing so takes everything up a notch.

.

12. Belongings:

This upcoming app’s elegant and overtly high-end-looking design gives it the right to declare itself “Premium,” especially since it has managed to turn one of the ugliest experiences on the Web (Craigslist.com) into something much easier on the eyes.
