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

A prototype we had to make for school.

This is an expand/collapse menu example that can be created using container states.

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.

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/

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.
