With over 4,900 questions across 24 categories, the app ensures comprehensive coverage of key technologies and prepares users for real-world interview scenarios.
99cards.dev operates on the principles of spaced repetition and active recall, two evidence-based learning techniques that significantly enhance knowledge retention. The system presents flashcards containing technical questions and answers, which users must answer from memory. Based on their performance, the algorithm schedules future reviews at optimal intervals to ensure long-term retention.
Users engage with short, focused quizzes (20–25 minutes per session) that cover key concepts in web development. After each quiz, they receive immediate feedback, detailed explanations, and insights into their performance. This allows them to identify weaknesses and improve continuously. The app also includes progress tracking tools that help users monitor their growth and stay motivated throughout their learning journey.
