Lingden: Learn languages

Lingden teaches you a new language the way fluent speakers actually use it — through real sentences, not isolated words.

🌍 16 LANGUAGES TO CHOOSE FROM
Arabic, Chinese, Danish, Dutch, French, German, Greek, Italian, Japanese, Korean, Norwegian, Portuguese, Russian, Spanish, Swedish, Turkish — with curated A1–B2 decks for each.

EVERY CARD IS A REAL SENTENCE
• Word-by-word breakdowns with English translations
• IPA pronunciation guides for every word
• Native audio for the sentence and individual words
• Multiple meanings + context

SPACED REPETITION THAT ACTUALLY WORKS
A 5-box Leitner system brings hard cards back sooner and easy ones less often. You see the right card at the right time, every time — based on how well you remembered it last time.

CURATED + CUSTOM
• Thousands of curated cards per language across A1–B2 levels
• Add your own cards from any word you encounter
• Verb-conjugation packs surface every form together
• Filter by topic, level, or your own creations

EVERYTHING SYNCS
Sign in once and your progress moves with you — between Android, iPhone, and the web app. Pick up exactly where you left off, on whichever device is closest.

GAMIFICATION DONE RIGHT
Daily streak, XP, level-ups, and milestone celebrations — without the dark patterns. No popups urging you to spend. No fake "you'll lose your streak!" notifications. Just a clear daily goal and a satisfying ratchet when you hit it.

PRIVACY-FIRST
Your account is yours. Email + password or Google sign-in. No ads, no third-party trackers, no analytics SDK shipping your data to marketers. Crash reports use Sentry (the only third-party) and contain no personal data.
