The recently released Google Inbox app is a re-thinking of the email inbox experience that beautifully demonstrates Google's material design interactive animation language. This prototype focuses on the compose button's animation. Click the + to reveal a new state where a wave of buttons and labels float up, and the + becomes a pencil icon. It uses two states, with staggered animations.

Finding language learning resources can be a time-consuming hassle. This app makes your search easier by exposing you to well-designed resources. Save the ones that strike your fancy and dabble, or get the app to arrange them into a structured, daily study schedule for you. Then track and share your progress. It's that simple. You can share your progress

The project contains numerous examples completed using variables and conditional logic.

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!
