Stop forgetting what you study. We use proven spaced repetition to help you master any subject for the long term. Just log your study sessions, rate how hard they felt, and let the algorithm schedule the next review at the right time. You focus on learning, not figuring out when to study again. KEY FEATURES Study smarter, not harder SM-2 calculates exactly when to review, so you spend less time on what you already know and more time on what you still need. That means fewer crammed rereads and better retention over time. Organize everything you study Break complex topics into clear groups and subtopics. Works great for exam prep, medical school, law, certifications, and any structured curriculum you need to track and revisit. Log sessions in seconds Record a session fast and choose a difficulty rating (Easy, Good, Hard, Extremely Hard). The app uses your ratings automatically, so your schedule adapts as you improve. Visualize your progress See your learning progress with calendar views, streak tracking, and detailed session history. Quickly spot what you’ve mastered and what needs attention next. Track multiple subjects Keep your entire coursework in one place. Each subject gets its own schedule, topics, and progress tracking, so you can study everything with confidence. Built for students preparing for exams and anyone who wants a reliable, science-backed study system that actually helps you remember.
