A Sign up - Sign in page example project using Variables and States to validate the correct user input in both pages.

A project which uses Vector Animations to recreate popular social app interactions.

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

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.

Created using Proto.io library of fully interactive, native watchOS components.

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 an example of a sign in screen that validates a username and a password. Feel free to import this fully editable project into your own account for use in your prototypes. Use the following to successfully sign in and proceed to the next screen User Name: john Password: proto.io

A Simple recreation of the Messenger bubble using Proto.io stock images. Basic functions such as drag/drop to screen corners, drag to the bottom to delete, swipe down to reveal 'contents hidden' to bring the bubble back to the screen and tap bubble to show conversation.

Using color adjustment and filters, I've simulated the iOS spotlight animation. Learn how you can apply these filters at https://proto.io/en/new-features/adjustments-filters/
