QuackDeck: Smart Flashcards

QuackDeck — A flash card app like none other!

QuackDeck is the flashcard app built around the science of memory. A proven spaced repetition algorithm watches how you learn and shows each card at exactly the right moment.

Make a card in seconds

📷 Snap a photo of a textbook, whiteboard, or handwritten notes
🔍 Scan documents with OCR
🎙️ Record audio for pronunciation or lectures
🎬 Record video for visual demos and clinical signs
📎 Upload images, diagrams, or X-rays
✏️ Type classic Q&A cards
A scheduler that learns you

QuackDeck is powered by FSRS — one of the most accurate spaced repetition algorithms available. After each review, rate the card Again, Hard, Good, or Easy. Nail it and it waits weeks. Struggle and it comes back sooner. Every card builds its own memory model, personalized to you.

Set a target retention level (70–97%) and QuackDeck calibrates your whole library to hit it.
