Flashcards, but handwritten. Ink Flashcards lets you write, draw, and sketch directly on flashcards with Apple Pencil or your finger. Create rich cards with handwriting, text, images, and audio, then study with spaced repetition, quizzes, typing, matching, cloze deletion, and games. Sync your decks across iPhone, iPad, and Mac with iCloud. Import existing decks from CSV, organize cards with tags and topics, and track your progress with review history, heatmaps, and retention stats.
