Try a real card from each app: tap it, then rate it.

The family

Pick your subject.

Each app has its own carefully written decks.

The films

Six apps, one short film each.

Short narrated tours. Each one plays on its app's page.

Spaced repetition

Cards you miss come back sooner. Cards you know wait longer.

Flip a card, rate it Again, Hard, Good or Easy, and each app keeps the schedule for you.

  1. Recall

    Read the question and answer it in your head before you flip the card.

  2. Rate

    Tell the app how it went. Honest ratings make a better schedule.

  3. Return

    Open Today and the cards that are due are waiting, with a few new ones and your daily goal.

The gap before the next review grows each time you remember a card.
