A simple implementation of Pull to Refresh

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

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.

Hi there! I would like to share with you the latest version of Spotify prototype. Now you can listen to music while browsing the prototype.

Custom Android KitKat Scrollable Tabbar

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.

This simple prototype demonstrates how have a container expand and collapse while moving adjacent content in sync.

"It’s still all ones and zeros!" We got inspired by this article on Quora (https://www.quora.com/How-could-Googles-new-logo-be-only-305-bytes-while-its-old-logo-is-14-000-bytes) that talks about the Google logo and how it consists of circles and rectangles. So we set off to validate this inside Proto.io (https://proto.io). Proto.io is particularly strong for it’s interactive UI Libraries but it’s web based editor also offers great support for basic shapes like ovals, lines and rectangles. So we recreated the Google logo using only rectangles and circles and what do you know! It all checks out! Having done all this in Proto.io that it also known for it’s pretty neat animation capabilities, we went a step further and created a cool animation that shows how it’s all done. For even more fun you can even import it in your own Proto.io account and edit it! Enjoy!

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.
