    Built so that words stay

      Words return after 1, 3, 7, 14 and 30 days. After a mistake, the word comes back sooner.

    • Four ways to practise

      Flashcards, spelling, multiple choice and matching pairs.

    • Your own pace

      Set a goal of 5, 10 or 15 words a day and keep your streak going.

    • Your weak spots

      WordStay collects the words you get wrong so you can train exactly those.
