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.

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.

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 is the companion prototype to a 2-part tutorial where we explore the utilization of variables to help us to recreate Apple’s native iOS Weather app. In both tutorials, we go over the different ways Proto.io makes variables available to use in building your prototypes - from the simple example of setting a value in the variables manager and utilizing that value in the prototype to creating and setting a custom variable based on the property of a container and then to the more advanced usage of ternary operators to affect an outcome based on conditions surrounding that custom variable. http://docs.proto.io/videos/ios-weather-app-variables-tutorial-part-1/ http://docs.proto.io/videos/ios-weather-app-variables-tutorial-part-2/

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!

Interaction prototype of the image behaviour from the Facebook Paper app.

If you need to get the Y position of a vertically scrolling container, create a text box. Then on the container scroll trigger, set a variable that evaluates the numerical callback value from the event (Y position). Then add a callback that changes the text property of the text box by reading from the variable.
