Basic To Do prototype based on: https://www.sketchappsources.com/free-source/3625-basic-to-do-app-design-sketch-freebie-resource.html

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

I used the Sketch "Delicious" free UI Kit for a food recipes app. It includes 11 pixel-perfect screens. I just added Proto.io interactions and created a great prototype! This Delicious UI Kit was designed by Robert Anitei Sketch source: https://www.sketchappsources.com/free-source/1765-delicious-ui-kit-sketch-freebie-resource.html

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.

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.
