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.

This one-screen prototype demonstrates some of Proto.io animation functionality.

Just testing out what sharing projects is like in proto.io. Not a real project.

This is a prototype of an app that pairs with a fitness track called Pulse Band. Pulse Band can count steps, measure heart rate, count stairs climbed, and also measure blood pressure.

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

This was an app I created to answer the question of "what's there to do tonight?" in the Richmond, Virginia area.
