DELF Pass

Stop forgetting French words. Master DELF vocabulary with science-backed spaced repetition. Learning French vocabulary feels like pouring water into a leaky bucket. You study 50 words today, remember 10 tomorrow. Traditional flashcard apps force you to review words you already know while the ones you forgot never come back. DELF Pass fixes this with SRS (Spaced Repetition System), the same method used by polyglots and memory champions. Words you struggle with appear more frequently. Words you've mastered fade into long-term memory with perfectly timed reviews. Why DELF Pass works: - Start studying in under a minute: Pick your level, start reviewing. No deck creation or import needed. - Complete DELF coverage: All 4 levels (A1-B2), organized by CEFR difficulty. - Audio pronunciation: Hear every word spoken aloud with text-to-speech, works offline. - Grammar + example sentences: See how words are actually used, with grammar patterns and real examples. - Progress tracking: Visual stats show exactly how much you've mastered per level. Built for: DELF exam candidates, French learners building real vocabulary, and anyone serious about French fluency. No gamification. No distractions. Just efficient learning. Premium: One-time purchase unlocks unlimited daily words and full level access. No subscriptions. Ever. Your data stays yours: Works fully offline. No account required. No ads. Minimal permissions.
