Smart Menu is a smartphone app that allows students to create their own health goals and uses those goals to find healthy restaurants and food options nearby. Smart Menu collates menu data from the restaurants and individual reviews from students. This data plus the health goals allow the app to help students find healthy eating options.

This is a UX design prototype for Pandora's Android app (from October 2014), adding a "Driving Mode" and lateral navigation between stations from the Now Playing screen. I took a challenge to redesign Pandora's Android app or add features at my discretion. Focusing on the Now Playing screen where users probably spend most of their time, I identified two areas in which I wanted to improve its UX: station identification and navigation, and its user experience while on the go. A 7 minute 25 second presentation of this demo with commentary is available on YouTube: http://youtu.be/LyH6Gl580OY A full write-up of an earlier, pre-Proto.io iteration of the design (along with a downloadable pdf) is available at http://edwinli.com/ux/portfolio/pandora-driving-mode/.

I created a prototype of the UBER app for Android in order to demonstrate what is possible using Proto.io. This project was a massive undertaking as my goal was to simulate the user experience of what it would be like to order 4 different UBER cars in San Francisco. I plan on doing a full "behind the scenes" article on my website about the challenges I faced along the way simulating the UBER app in Proto.io. Special thanks to the awesome team at Proto.io for all of their tireless assistance along the way!

An as close as possible copy of the IFTTT onboarding experience. This prototype is also made in 4 other tools (Pixate, Origami, Framer & Form) to compare the differences between them.

An extended collection of fully animatable UI libraries like triangles, stars, arrows and more, let you bring your idea to life all within Proto.io.

This is a custom tablet prototype of my take on a popular carnival attraction called the shooting gallery. I wanted to show everyone how versatible and powerful the Proto.io tool is and demonstrate that anyone can make video games using Proto.io. This prototype was inspired by various versions of the classic game created for mobile devices released a few years ago. This is meant for educational purposes only.

I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

This one-screen prototype demonstrates some of Proto.io animation functionality.
