HOW IT WORKS
Tap a card to flip it — or switch to swipe gestures (right = hit, left = miss) for a less crowded back face. Mark your answer and move on. Cards you miss come back more often through smart weighted shuffling — so you spend time on what you actually need to learn.
Pick your level, pick a deck, and start reviewing. That's it.
