G-Watch is a stop watch and a countdown timer with all features you’ll expect of a stopwatch.

As an additional feature there is GPS support. You can (you don’t have to!!) use your GPS device to monitor your training session. You can export your sessions to CVS (e.g. for Excel), KML or GPX (e.g. for Google Earth).
