See how it works
The home page walks through the flick, the spaced-repetition scheduling, and the two deck goals. The short version: tap to flip a card, fling it off the deck to rate it, and only the cards that are due show up each day.
Add more decks
The deck library has free ready-made decks: Spanish essentials, world flags, the constellations, major bones, the periodic table, Morse code with audio, and more. Each imports with a tap. Or start from your own spreadsheet with the .flickdeck format guide.
