Rappel

Rappel shows each card again just before you would forget it, so a few minutes a day are enough to remember what you learn. After each card you only say whether you knew it: Fail or Pass.

Cards are written in Markdown, with formulas, images and sound. Everything stays on your computer: Rappel never goes online and needs no account.
