Study flashcards the way memory actually works. FlashLeaf uses real spaced repetition to resurface each card at the exact moment you're about to forget it β€” so you remember more in less time, and it sticks. Most flashcard apps just flip cards. FlashLeaf runs a genuine adaptive review engine: grade each card Again, Hard, Good, or Easy, and it schedules every future review for you. As you study, a living garden grows on screen β€” visible proof that your knowledge is taking root. WHAT YOU GET - Remember longer with an adaptive spaced-repetition engine that plans every review - Build unlimited decks for any language, exam, or subject and add cards in seconds - See what's working with retention %, review history charts, a study heatmap, and a forecast of what's due next - Stay consistent with day streaks and a longest-streak record that reward showing up - Find any card fast by searching the front or back across all your decks - Never lose momentum with a daily study reminder that keeps the habit alive PERFECT FOR - Students cramming for exams and finals - Language learners drilling vocabulary - Professionals mastering a new field or certification - Lifelong learners who just want to stay sharp WHY NOT JUST USE PAPER CARDS OR A NOTES APP? Paper can't tell you which card to review today, and a notes app can't schedule your memory. FlashLeaf does the timing for you β€” reviewing only what you're about to forget β€” so every minute of study counts. PRIVACY Your decks and progress live on your device. No ads, no tracking, and it works 100% offline. FULL ACCESS FlashLeaf Premium unlocks the complete app: unlimited decks and cards, the full adaptive review engine, and every retention insight and forecast. Choose the plan that fits β€” weekly, yearly, or a one-time lifetime purchase. Plant your first seed of knowledge today.
