A simple, one page prototype inspired by Ramotion's Contact Sync (https://dribbble.com/shots/1749645-Contact-Sync?list=users&offset=11). Just play with the on/off switches.

A demo created using draggable and rotation features.

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.

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.
