I use google docs. I have the following tabs: Date, Result,Casino, Approx Hands, Approx Advantage, Average Bet, EV. Then I have tabs for what I was doing: Counting 21, 3cp, unnamed cool thing 1, unnamed cool thing 2, poker, other AP, weekly freeplay & promo cash, and the -EV stuff: gambling (recreational or for cover), and tips. I also have a big column for comments. It is a pretty good list, there are a few things I would change. Sometimes I keep great records, sometimes I am real lazy and just fill in the "results" column.
