Duolingo, Anki, tutors, immersion, books — log it all in one place. WHY FLUENCY STREAK The hardest part of learning a language isn't the grammar or vocabulary. It's showing up every single day, for months and years. Fluency Streak is designed around one truth: consistency beats any method.

Language learning that actually works. Roleplay real-life scenes in Spanish, French, and Italian. Get instant feedback on every response. Track your fluency with a science-backed rating — not streaks. PRACTICE WHAT YOU'LL ACTUALLY SAY Order coffee in Buenos Aires. Check into a hotel in Rome. Make small talk at a dinner party. Every scene is something you'd actually use — not disconnected vocabulary or contrived sentences. FEEDBACK ON EVERY RESPONSE After each thing you say, you get specific notes on grammar, word choice, and natural phrasing. The feedback prioritizes what matters at your level: first, can you be understood? Then, does it sound natural? Then, is the grammar tight? That's how real fluency builds. ADAPTIVE TO YOUR LEVEL New to the language? Start with structured choices. As you improve, the app weaves in more freeform writing so you're always practicing at the edge of your ability — not grinding through easy drills or hitting a wall. A RATING THAT MEANS SOMETHING Dialog Engine uses a research backed fluency rating based on the ELO system — the same math that ranks chess players. It moves based on how you perform relative to the difficulty of what you practice. It has been validated to have a 0.90 correlation with CEFR, the international standard for language proficiency. When your rating goes up, your fluency actually went up. NO STREAKS. NO OWL GUILT. No push-notification guilt trips. No fake progress bars. No daily streak anxiety. Practice when you want, for as long as you want. The rating is the feedback — everything else is noise. LANGUAGES Spanish, French, Italian — with more on the way. — — — Dialog Engine Unlimited gives you unlimited conversations, AI feedback on every response, and full access to all scenes across all languages. Subscription options: - Unlimited Monthly — $4.99/month - Unlimited Annual — $29.99/year (save 50% vs monthly) - 7-day free trial available on either plan Payment will be charged to your Apple ID account at confirmation of purchase.
