FlashStacks vs PaperFlip

Your flashcards, on your Home Screen. FlashStacks turns your study cards into Home Screen, Lock Screen and StandBy widgets. Glance at a question between classes. Tap to reveal the answer. Tap again for the next card — all without opening the app. Learning fits into the moments already filling your day. ALWAYS VISIBLE, ALWAYS READY Widgets come in every size and rotate through your stacks automatically, so every time you pick up your phone there's something new to learn. Start a study session and your card follows you to the Lock Screen and Dynamic Island as a Live Activity. AI DECKS FROM YOUR NOTES Upload any PDF — lecture slides, textbook chapters, study guides — and AI builds a complete deck in seconds. Choose High-Yield for exam prep or Comprehensive for full coverage. FlashStacks even finds the diagrams in your PDF so you can turn them into image occlusion cards. LEARN A LANGUAGE FlashStacks Learn gives you ready-made packs in French, Spanish, Japanese, Korean and Mandarin — greetings, numbers, food, travel and more. Add a pack and pick up new words from your Lock Screen all day. SPACED REPETITION THAT WORKS FlashStacks uses the same proven science behind Anki. Cards you struggle with come back sooner. Cards you've mastered fade into the background. Study smarter, not longer. IMAGE OCCLUSION CARDS Add any image — diagrams, anatomy, maps — and draw boxes over the parts to hide. Tap to reveal what's underneath. Perfect for visual subjects. BRING YOUR CARDS WITH YOU Import from Anki, CSV, TSV or JSON. Search every card across all your stacks and keep them organised with tags. BEAUTIFUL BY DESIGN Every stack gets its own colour palette — soft pastels or bold modern tones — and your widgets match. Dark mode uses pure OLED black. TRACK YOUR PROGRESS See mastery, difficulty breakdown and 14-day activity for every stack, plus a study calendar across everything you've learned. Build a streak. Hit your daily goal. FLASHSTACKS PREMIUM Unlock unlimited stacks, AI deck generation from PDF, image occlusion cards and every FlashStacks Learn pack. Free accounts include up to 2 stacks. Monthly and annual plans available. Annual plans include a discounted first month. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Drop in your source — a course PDF, a lecture video, a research paper, an article — and PaperFlip generates clean Q&A cards from the content that actually matters. Edit before saving, then study with a spaced repetition engine that knows exactly what to show you tomorrow. HOW IT WORKS 1. Drop in a source — a PDF, a YouTube URL, or any web article 2.

Every generated deck is yours to edit before saving. The spaced repetition engine schedules each card individually based on how well you remember it. You review what's about to slip and skip what's sticky. That's how a 30-minute study session is worth more than three hours of re-reading. WHO USES PAPERFLIP Students processing dense reading lists. Self-learners turning videos and articles into reviewable knowledge. Professionals preparing for certifications, interviews, or licensing exams. Anyone tired of typing flashcards by hand.
