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.

A basic example of reproducing Instagram info bars behaviour. A list header floats over the list's items and remains visible at the edge of the screen until it is replaced by the next list header

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.

Basic Resume Design

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

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.

This prototype shows a subtle animation of avatars flying in, and subtle background tint changes. See how it was created step-by-step: http://docs.proto.io/videos/prototyping-subtle-animation/ >starting at time: 28:40 Enjoy...

Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes. I have made a companion tutorial video where you can see exactly how I did it. This video is available here: http://docs.proto.io/videos/recreating-tumblr-compose-animations-in-proto-io/

Apply color adjustments and filters to your prototypes to create beautiful interactions and animations. https://proto.io/en/new-features/adjustments-filters/
