Struggling to retain what you study? Most flashcard apps just let you type cards by hand and flip through them randomly. Revv-AI Flashcards takes a fundamentally different approach - it analyzes your study material, tracks how well your memory is holding up, and adapts every session to focus on the cards you are actually at risk of forgetting. Revv-AI is built for students, professionals, and lifelong learners who want every minute of study time to count. Import a PDF, let the AI generate a complete flashcard deck, then follow a session designed around your personal recall data. The app monitors your overall recall probability across each deck, grades your retention health from A+ to F, and shows you exactly how many cards you remember, which ones are slipping, and which ones are already forgotten - so you always know where to focus next. KEY FEATURES - AI Deck Generation - Import any PDF and the app extracts content page by page, then generates ready-to-study flashcard decks automatically. - Recall Probability Tracking - Each card is scored with a recall probability. The app separates your cards into Recallable, At Risk, and Forgotten groups so you can prioritize intelligently. - Health Grade System - Your deck receives a letter grade (A+ through F) based on your overall retention, giving you an instant snapshot of how well you know the material. - Adaptive Study Sessions - Sessions are structured around your current recall data, not a random shuffle. Cards you are losing track of come up more often. - Study Insights - After each session, review a personal insights summary covering session duration, cards reviewed, and progress trends over time. - Streak and Calendar Tracking - A built-in study streak and calendar view keep you consistent day after day. - Deck Categories - Organize decks by subject or category so your library stays easy to navigate as it grows. - Revv Pro Subscription - Unlock expanded limits and premium capabilities through an optional in-app subscription. - Sign in with Apple - Create your account securely with a single tap using Sign in with Apple. - Local Data Persistence - Your decks and study history are saved on-device so your progress is always available. HOW IT WORKS Start by importing a PDF of your study material - a textbook chapter, a set of lecture slides, or a reference document. Revv-AI processes each page, extracts the key content, and generates a flashcard deck for you. Once your deck is ready, you can review and organize it before your first study session. During a session, the app presents cards based on your recall data. As you progress through cards, your recall probabilities update in real time. When the session ends, head to the Insights screen for a full breakdown of your performance - how long you studied, your overall recall score, and which areas still need work. Over time, the home screen streak tracker and calendar show your study consistency, helping you build the kind of regular practice that leads to lasting retention. Whether you are preparing for a standardized test, a professional exam, or a university course, Revv-AI keeps your study plan grounded in data rather than guesswork. Your data stays on your device and is tied to your secure Apple account. No complicated setup, no manual card entry required to get started.
