About

Countdown Color Timer

Features
Read full description

This is just another countdown timer, but with a focus on displaying of halves and quarters on four different views. You can set hours, minutes and seconds. The yellow fields turn red the last 10 seconds. It might be 'useful' to some people to have a stand-alone app for doing just this. To see more apps like this, go to www.discobajas.com
