LearnBack vs LLM Master

Stop forgetting what you read, watch, and study. LearnBack turns everyday learning into long-term memory. Capture what you discover, recall it in your own words, and review it at the right time with active recall and spaced repetition. Whether you are preparing for exams, learning a new skill, reading books, watching educational videos, or collecting ideas, LearnBack helps you build knowledge that stays with you. REMEMBER BY RECALLING Learning is not only about consuming more information. LearnBack asks you to retrieve what you learned in your own words, helping you move from passive scrolling to active learning. CAPTURE BY TEXT OR VOICE Save a quick written recall or record your thoughts while reading, studying, commuting, or watching a video. Add a title and tag so every idea stays organized. BUILD PERSONAL FLASHCARDS Turn your own recalls into flashcards based on the ideas that matter to you. Your cards come from your learning—not a generic deck. REVIEW AT THE RIGHT TIME Use spaced repetition to revisit important ideas before they fade. Rate each review as Again, Hard, Good, or Easy, and keep strengthening your memory over time. YOUR LEARNING TIMELINE Browse your recalls by date, replay voice notes, revisit written insights, and build a personal history of what you have learned. INSIGHTS THAT KEEP YOU MOVING Track your daily streak, recall activity, review progress, and learning categories. See small steps become a lasting habit. LEARN WITHOUT BURNING OUT Optional eye-care reminders support the 20-20-20 rule, while stretching reminders encourage you to move during long learning sessions. PRIVATE BY DESIGN No account required. No cloud storage. No external servers. Your learning stays on your device, and LearnBack does not collect your data. PERFECT FOR • Students and exam preparation • Books, articles, courses, and podcasts • Language and professional learning • Coding and technical concepts • Lifelong learners and curious minds • Anyone tired of forgetting useful ideas Learn less passively. Recall more actively. Remember for longer. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://learnback.lovable.app/
