InerziaTimer is a simple but powerful countdown/chronometer/alarm clock for the Mac, completely written in Cocoa. You won't lose a second again, with InerziaTimer!

InerziaTimer does exactly what real chronometers do: if you can measure it with a professional chronometer, you can do the same with your Mac. With a precision of 1/100 seconds, you'll be able to time about everything with a precision never seen before. And there are features for every need: simple shortcuts, laps, export and customization are all available in InerziaTimer.

Even digital wristwatches have a countdown built-in, so why your Mac doesn't have more...
