Stop forgetting what you learn. REVU schedules reviews at the perfect moment — so knowledge sticks. Private, adaptive, and built on proven cognitive science. REVU – Learn better. Remember longer. REVU is a spaced-learning app that helps you turn important knowledge into lasting memory. Built on proven cognitive science, REVU schedules reviews at the moment you're most likely to forget—so every session strengthens what you already know instead of wasting your time. Whether you're studying for an exam, learning a language, working with technical standards, or simply trying to remember what matters, REVU keeps your memory sharp with a simple daily routine. How it works Create your own cards Add questions and answers in your own words. Attach images, diagrams, screenshots, formulas—anything that helps you understand the concept. REVU can even extract text from images using on-device OCR. Review at the right time The app shows you exactly what needs reviewing each day. Cards you know well appear less often. Cards you find hard return sooner. Choose between two proven algorithms—SM-2 (classic) or FSRS (adaptive)—for each topic. Answer and improve Test yourself, type or dictate your answer, then reveal the solution. Rate how difficult it felt. REVU updates each card's stability and schedules the next review automatically. Optional AI answer checking Choose between: - Local processing (on-device) for full privacy - ChatGPT for semantic feedback and guidance Only your question and answer are sent—never images or personal data. Powerful features for real learning - Adaptive spaced repetition that adjusts to your memory - Choose SM-2 or FSRS algorithm per topic - Image support on both sides of a card - Full-screen image viewer for diagrams and notes - Fast dictation using on-device speech recognition - OCR text extraction from screenshots and photos - Dark and light modes with clean, focused UI - Optional reminders that respect your focus time - Local-first storage: everything stays on your device - Private iCloud sync across your Apple devices REVU is designed to stay fast and stable even with hundreds or thousands of cards. Privacy built in Your data stays yours. All content is stored on your device and, if you enable it, synced only through your private iCloud account. No external servers store your notes, images, or learning history. AI features are fully optional and transmit only the text needed for answer verification. Perfect for - Students and exam takers - Engineers, doctors, lawyers, and technical professionals - Programmers learning new tools or frameworks - Language learners - Anyone who wants to remember what they learn REVU turns cognitive science into an everyday habit—so knowledge becomes something you keep, not something you lose.
