A Lotus 1-2-3 spreadsheet written for the HP95LX that performs the traditional Biorhythms calculation and shows the output in a nice graph. Nothing fancy, just for fun.
(Could run on the HP100LX or HP200LX but the screen probably won't look right -- 40 characters versus 80 characters width.)
No fee. Not shareware. (Copyright retained.) Have fun.
