What typically works for me is just pencil and paper. I have a notebook that I use to log notes for each business day of the week. If I'm having trouble figuring out what I was working on during the previous day, I simply look at the previous day's notes. Writing notes helps commit things to memory better for me too. Also, using paper to write notes is less of a distraction than using an electronic medium to write notes in this day and age.
