ChronMaster is primarily a tool for mastering who is in what timezone.
With it, you can create a button to cycle through up to five time-zones with the current time and a label - such as the timezone or the person who is there.
Meaning... cycle through Jake in Utah, Fred in London and Barbs in Berlin, with their current time, all on one button.
Also includes a count-down timer that can launch a website at zero, and a stopwatch.
