Flashcards that schedule reviews before you forget

The verdict

Free and open source on the Mac, with free AnkiWeb sync, this spaced-repetition app shows each card right before you're likely to forget it and copes with decks of 100,000+ cards. The only thing you pay for is AnkiMobile at $24.99 once, which beats the subscription copycats its developer warns about. Expect a learning curve, because you build or import decks and tune the settings yourself.
