Accord is the only app built specifically to drill one of the hardest parts of learning Spanish, French, Italian, and Portuguese — grammatical gender. Every noun has a gender. Get it wrong, and your adjectives, articles, and pronouns all fall apart. Most language apps test you on it without teaching it. Accord fixes that. SWIPE TO LEARN Swipe-style flashcards make drilling gender feel effortless. Swipe left for masculine, right for feminine. Simple, fast, addictive. FOUR LANGUAGES, 4,000+ WORDS Spanish, French, Italian, and Portuguese — all in one app. Switch languages instantly. Every word comes with phonetics and translation. SENTENCE-BASED AGREEMENT CARDS It's not just articles. Accord teaches the full agreement chain — adjectives, partitives, indefinites — so you understand why la maison est grande, not just that maison is feminine. COLOR-CODED REVEALS After every swipe, see the complete gender agreement highlighted in blue (masculine) or pink (feminine). SPACED REPETITION Words you miss come back more often. Words you know fade into the background. Efficient, science-backed learning. WORD LOOKUP Studying specific vocabulary? Look up any noun and add it to your deck. FREE VS PREMIUM Start free with the 100 most common words in one language. Upgrade to Premium to unlock all 4 languages, 4,000+ words, word lookup, and ad-free learning. Gender mistakes are embarrassing. Accord fixes them. Key Features: Spanish/French/Portuguese/Italian Support: Over 1,000 words per language, comprising a mix of nouns complete with articles, phonetics, and translations most commonly used adjectives seen in sentences. Interactive Flashcards: Swipe left or right to match the correct article with the word. Track Your Progress: Build streaks and see how quickly you improve with real-time feedback. Learn at Your Own Pace: Choose the number of words per round—10, 20, or even 50! Engaging Gameplay: Improve your skills with a game-like interface that makes learning fun and addictive. How It Works: Studying regular flashcards is boring, but this game makes flashcards fun. Simply swipe left or right to match the word with the correct article. At the end of each round, view the words you missed along with their correct article and translation. Who Is It For?: Accord is perfect for students, travelers, or language enthusiasts who want to improve their language and grammar skills quickly and effectively.

Verdict

The call

The clearest difference is review sentiment: Accord at 100% against Duolingo's 65%. Accord also leads on ads (none vs shown) and rating (5.0 vs 4.7). Duolingo's advantage is update cadence (weekly vs every 9 months) and ratings volume (5.5M vs 6). On price, in-app purchases, monetization model and device support there is nothing between them.
