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 prototype is addressing the payment portion of the Car2go app. The current mobile app has no options to manage any payment information. Use the blue car icons or the hamburger navigation to view the proposed payment portion.

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.

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.

A beautifully animated Slide in Menu created exclusively with Proto.io. Feel free to import this fully editable project into your own account for use in your prototypes.

Project using Variables to simulate Drag and Drop to Snap functionality into a predefined area. While also adding Animations and States for a more smooth and elegant process.

'Cook it' is an app where users can find recipes based on ingredients they have at home. This project uses variables to add ingredients to the list using a single input field. I created the loading animation using a group of images which rotate into a pot. I used cloning and obscurity transitions in the recipes screen to display the recipe when it's tapped.
