NFP For the Palm Pilot

I found a really great program, thanks to Alicia, that puts an Natural Family Planning or NFP program on your palm pilot and at your fingertips. It seems to do everything that some of the pricey computer programs do, but for free! I wish I could do more with it, but I can't since I'm pregnant. But after this baby I'm going to be VERY careful about keeping track of my fertility. I'd prefer these happy little surprises to be a little better spaced next time! For my own sanity, of course.
