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.

iOS app prototype using the magnificent Proto.io that let users share their stories about their travel. A work in progress but definitely in good direction! To experience, simply click anywhere on the main screen. On mobile, tap on the password field and then tap done.
