How 99cards.dev Works

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.

Core Benefits and Applications

The system is ideal for developers who want to improve their interview performance, secure better job offers, and advance their careers. It is particularly beneficial for those who struggle with traditional study methods and need a structured, science-backed approach to learning.
