Here's a demo showing a basic color picker using a container with 4 states for both the colored star and the color swatches.

Designers can use their favorite design tools like Photoshop and Sketch to design the finest details of the user interface for their app. Single or multiple touch interactions can be applied on any UI element (layer) on each screen. Sophisticated animations can be created on-screen as well as screen transitions, using the powerful timeline animation features that Proto.io offers.

This prototype is a simulation of one part of the Pandora iPhone app. I have chosen to simulate the part of the app where the user selects a Pandora radio station and then proceeds to select that station. What I have demonstrated is how how the radio station animates from a small entry on a list to a large full screen entry and vice versa. If you would like to see how I created this prototype, please watch this video tutorial here: http://docs.proto.io/videos/pandora-tutorial-part-1/

Create top 5 lists about anything with photos.

Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here: http://docs.proto.io/videos/recreating-tumblr-compose-animations-in-proto-io/

A score based filter system that I hacked using variables. Each of the 10 cities is assigned a score for avg temperature, Taxes, and Cost of living, and when the sliders correspond to those values cumulatively, those cities show up on the map.

This is the prototype of my favorite music player, Poweramp. I've tried to recreate the Plastic HD theme of the app interface and made it pretty close to the original visually which includes some of the transitions. This design has been made with Adobe Photoshop CC and Material Design Library of Proto.io. Hope you guys like it! Would love to know your views on it and how can we improve it :) Cheers! Aman P.S: Turn up the speaker ;)

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!
