SRS (Spaced Repetition System) is a personal learning and revision app designed to help users retain knowledge for the long term instead of forgetting it after a few days. It lets users organize content into subjects and topics, store detailed lessons, summaries, notes, coding examples, and reference links, and mark topics as either "to learn" or "learned." Once a topic is learned, the app automatically schedules future reviews using a spaced repetition algorithm based on the user's confidence and previous performance.
The app is aimed at students, software developers, and lifelong learners, with a strong focus on technical subjects such as DSA, programming, algorithms, and interview preparation. Each day, it generates a personalized review queue so users know exactly what to revise, helping them strengthen their understanding over time while spending less time reviewing concepts they already know well. The goal is to serve as a personal knowledge base and long-term memory system that makes learning more efficient and consistent.
