At this site you find information about my software PTimLog for 3Com's Palm/Pilot.

PTimLog is a program, which helps you to track your working times and projects. If you have to report the times you worked on projects or like to see how many overtime you have at a current date (or how much you have to work until years end), then this may be the right program for you. In addition, PTimLog can handle different project-costs

PTimLog is published as shareware and costs 7 $ (8 EUR). However, you can test it as long as you like. But if you like to use it regulary, please register and support future development.
