Flashcards
Real spaced repetition, built in. Cards you know come back less often; cards you miss come back sooner. Pick a deck that follows the plan, drills vocab by level, or covers everyday sentences. Flip the direction with the toggle, or turn on hints: each card has a crossword-style clue that makes you think without giving the answer away. Your progress saves on this device, no account needed.
How the ratings work: Again means you missed it (it comes back this session). Good schedules it normally. Easy pushes it further out. Over days, the algorithm spaces each card to the edge of your memory, which is what makes flashcards actually stick. Progress is stored in this browser only, so it won't sync to your phone.
