The poolcalc webpage can be saved to your desktop so it can be used off-line if needed. It's a really user friendly way to show all of your test results and chemical needs on the same page.

Bleachcalc is a great tool, too and is really good at giving you the data for one chemical at a time. After you've been testing for a while, either tool will do the job.
