Here is a prototype of a music player. Click play and add different sort of beats to the audio. Sample audio is from http://tricoolore.com/ Enjoy!

An example of a low-fidelity prototype, showing just enough details to give users an idea of what this app could do. Getting feedback through moderated user testing is best in this initial phase. The app's objective is to help you record your daily expenses, see an outline of your month's finances and compare spending with previous months/periods through charts.

Animated storyboard using low fidelity assets created in Proto.io, and icons found within the Proto.io library and Noun Project. The "On Screen Show" screen interaction is used to animate the content through a sequence of callbacks. See how this was made step-by-step in this webinar video on Low Fidelity prototyping: http://docs.proto.io/videos/low-fidelity-prototyping-with-proto-io/ TAGS: storyboard low fidelity auto-play

Proto.io comes with UI libraries for iOS, Android Material Design, Windows and Apple WatchOS so that people can easily drag and drop those elements to bring their ideas to life. Simple interactions can also be applied, primarily screen-linking and basic navigation.
