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.
