Cesium is the award-winning clock & timing software for the Palm Computing® platform. Cesium includes a clock with 3 alarms, a count-down timer and a stopwatch.  See the features list and screen shots below for a complete description of the application in action.  Or hey, just grab a copy and try it for yourself.

Cesium was written because I needed a precision stopwatch with a large digit display.  I program for fun.  I try not to take it too seriously. Please remember that when engaging in correspondence about this software. 

Where the heck are ClockWorks & Chronos?

Cesium runs on all Palm Computing® devices, including the Pilot 1000 & 5000, PalmPilot® Personal and Pro,  Palm III, Palm IIIx, Palm V and Palm VII devices and the IBM WorkPad.

I recommend that you install the most current OS update when using Cesium.  OS updates are available from Palm Computing.

Cesium seems to work in flash memory.
