Anki
Flashcards that know when you are about to forget
What it does
Anki uses spaced repetition to show you each flashcard just before you would forget it. Make your own decks or download shared ones.
Who it’s for
Language learners, medical students and anyone memorizing lots of facts.
Why it’s cool
Free on desktop, Android and web, and made by one developer for nearly two decades. The iPhone app is paid to fund it.
