Build an iPhone app for beginners who want to learn Spanish through short, game-like lessons. The main screen should show a simple lesson path covering greetings, food and everyday phrases, with completed lessons clearly marked. Tapping a lesson opens a short quiz with multiple-choice questions and sentence-building exercises. After each answer, show whether it is correct and give a brief explanation. At the end, show points earned and a button to return to the lesson path. Save points and completed lessons on the device. Use warm orange, cream backgrounds, rounded cards and playful animations, with an original look. Include realistic sample lesson content with Spanish phrases and English translations.

Vibecode builds a first version from one prompt, and the checker would start with these parts: a beginner lesson path for one language; short multiple-choice and sentence-building quizzes with answer feedback; points and completed lessons saved on the device. Plan on an afternoon for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Duolingo, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
Duolingo gives learners its own course library and years of learning data that a homemade lesson app would not have. A version you build yourself won't have these: Duolingo's full course library; years of learner performance data; Duolingo's language teaching team.
