PlanEx brings flashcards, spaced repetition, and a smart study planner together in one simple app. Studying for an exam? Learning a new language? Create flashcards, review what you've learned, and track your progress. PlanEx adjusts your review schedule based on how well you remember each card and how much time you have until your exam. FLASHCARDS FOR ANY SUBJECT Vocabulary, physics formulas, historical dates, or human anatomy. Turn any topic into flashcards. Add images, format text, highlight key information, and organize your cards into decks. SPACED REPETITION You don't have to remember everything on the first try. That's what practice is for. PlanEx uses spaced repetition, a research-backed learning method that helps you retain information over time. The algorithm tracks your answers and adjusts when each card appears again. Remember something well? You'll review it less often. Still struggling? You'll practice it sooner. EXAM PREPARATION One month until your exam? Or just one week? Set your exam date, and PlanEx plans reviews around your deadline and learning progress. Keep your preparation on track without having to schedule every session yourself. SMART STUDY PLANNER Check your study calendar, track your progress, and get reminders when cards are ready for review. Less time planning. More time actually learning. START FOR FREE Create your first flashcards and give your memory a workout. PlanEx is free to use. Upgrade to PlanEx Pro for more cards and additional features.
