Racki turns the vocabulary from your Duolingo courses into spaced-repetition flashcards — so the words you've learned actually stay learned. No account, no sign-up, nothing to configure. Open it and start reviewing. Enable the course sections you've finished and drill just those words — nothing you haven't reached yet. What you get: • Spaced-repetition review that resurfaces words right before you'd forget them • Two drill directions — meaning → word and word → meaning — each scored separately, so you can see which way needs work • Original script displayed alongside, so you can always check your reading • Choose exactly which sections are active and review only what matters now • Progress tracked automatically as you go • Works fully offline — the entire word set lives on your device • Your study data stays on your device: no account, no cloud, no sign-up • Free, kept that way by a single discreet banner ad — no pop-ups, no paywalls Supported courses (18 and growing): Arabic, French, German, Greek, Hindi, Irish, Italian, Japanese, Korean, Latin, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, Turkish, Ukrainian Racki is an independent companion app and is not affiliated with, endorsed by, or sponsored by Duolingo. "Duolingo" is used only to describe the courses whose vocabulary you can review.
