I do similar to the paper tickler but on an iPhone app, Awesome Note (ANote). I'm trying to learn about birds, and I've setup a note with reminder for each one. I've got notes for each bird I want to revise after a day, a week, a fortnight, a month and a quarter.
I setup the due dates manually, and after I've revised the notes I put at the bottom of the note I put the dates when I actually revised the info, and then manually adjust the due date again.
At first I wanted an app to remind me automatically, but I find that life happens, and I don't always revise when I'd like to, but doing it manually means that the next one is always spaced apart appropriately, if they were automatic I might get a reminder only two days after I've just revised it because I was late.
Also by doing it manually you can see if you've overscheduled reminders - 6 on one day? I'll push a few back.
