A simple to use timer in the form of a traffic light. Set whether you want it to run red-amber-green or green-amber-red, set the times in minutes and seconds and then off it goes! A bell chimes as each light changes.

Designed to be used as a behavioral aid for children - set the lights to go from green to red to time an activity ("10 minutes of quiet play before bed time" or to time siblings turns on the playstation!) or from red to green as a timeout timer.

It can also be used without the timer to teach how traffic lights work or as a behavioral guide.

There is an invisible reset button at the bottom right of the screen so you can return to the menu without waiting for the timer to finish.

Each light can be set from 5 seconds up to 99 minutes and 55 seconds (in 5 second increments).

Still buggy

The default setting works fine, but switching red and green only brings up a green light.
Is there a way to update the minute setting to a push and scroll function instead of a tap? In testing the app, I wanted to see the maximum number of minutes and seconds are available for each light. Imagine my surprise when I had to tap 98 times to get to the maximum length of time!

The idea is very good, but it should be updated to current iOS expectations.


Buggy does not work when swapping lights

Default setup works.
However, when swapping the red and green lights it doesn’t work
