Flippy is the flashcard app that brings cards back exactly when you're about to forget them. Learn less. Remember more. A STAGE, NOT A FORM Your decks live on a wallet of passes in front of a photo stage — chalkboard, water, sunset, chemistry, space, or your own photo. Glass navigation, paper cards, serif type. Dark, calm, focused. SPACED REPETITION THAT ACTUALLY THINKS Grade every card Again, Hard, Good or Easy. Each card keeps its own ease, its interval stretches as you remember, and a daily session picks what's due plus a few new cards. Memory-strength rings show what's fading. Leeches are flagged before they eat your time. Undo any answer. EIGHT WAYS TO LEARN Today's session · Quick 10 · New cards · Hardest cards · Reverse · Quiz · Write · Match · Cram. Deselect topics you don't want right now. Every session starts with a 3-2-1 countdown and your settings right there. QUIZ — POWERED BY APPLE INTELLIGENCE Multiple-choice distractors are written on device: plausible, same style, same topic, never the correct answer paraphrased. Match spreads pairs across the whole screen and races the clock. Write forgives typos. SCAN DOCUMENTS & SLIDES INTO CARDS Photograph pages with the document camera or drop in PDF slides and images. Text is recognized on device, then Apple Intelligence drafts your cards — long slide decks are split into chunks automatically. BRING YOUR CARDS Import Anki decks (.apkg, with images and subdecks), Anki text, Quizlet and Flashcard Hero exports (.flashcards, with images and topics), CSV and TSV. Export any deck or topic as a .flippy file with everything inside — text, photos, drawings, LaTeX and your learning progress. RICH CARDS Photos, PencilKit drawings, LaTeX formulas, cloze deletions, read-aloud in the card's language, scrollable long content. WIDGETS EVERYWHERE Today pass with goal ring and streak · interactive flashcard widget (flip and grade on the Home Screen) · streak & week · 14-day forecast · deck passes · learning modes · Lock Screen and Apple Watch complications · Control Center: start a session or mute today's reminder · a Live Activity keeps your session on the Lock Screen and in the Dynamic Island. STATISTICS THAT MOTIVATE Learning score, accuracy and volume trends, activity heatmap, hour × weekday grid, Leitner boxes, memory-strength buckets, forecast, deck health, records and insights — for the week, month, 90 days or the year. YOUR DATA STAYS YOURS No server, no account. Sync through your own iCloud. A trash keeps deleted decks, topics and cards for 30 days. FREE VS. PREMIUM Free: 2 decks with 2 topics and 40 cards each, every learning mode, statistics, import and export.

ReceptionRating · Positive reviews · Number of ratings

Flippy holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 19 and 91 respectively.

UpkeepUpdate frequency

Flippy ships an update weekly, Feyn every 9 days. The most recent releases landed on September 29, 2026 and September 27, 2026 respectively.
