Zynlo
Read full descriptionHide full description
Zynlo is a spaced repetition app for people who already have something to learn. Bring the material. Zynlo handles what happens after a card exists: it tests you in a way that produces real evidence, notices where recall breaks down, helps repair the gap while it is still fresh, checks the fix worked, and schedules the next encounter so the knowledge stays. WHY ZYNLO IS DIFFERENT Most flashcard apps show you a card, ask whether you knew it, and trust your judgement. Zynlo gradually asks you to produce the answer yourself. New material starts gently. As your recall becomes stronger, cards progress towards typed production so Zynlo can measure what you can actually retrieve rather than what you think you knew. When something goes wrong, the mistake becomes useful evidence rather than just another red card. BRING WHAT YOU ALREADY HAVE Import from Anki, including supported media and review history. Import from Mochi. Import CSV, TSV, JSON or Markdown files, including awkward files full of commas, quotes and formatting. Generate learning material in ChatGPT, Claude or another AI assistant and import the result. Or create cards yourself with formatted text, images and maths. Your learning material belongs to you. Zynlo is designed around studying it, not locking it inside a content catalogue. BUILD BETTER CARDS AS YOU LEARN Learning does not stop when the flashcard is created. Attach multiple notes, screenshots or photographs directly to a card without changing what the card is testing. Review all of your Notes & Images from the subject itself, while keeping them hidden during recall until they are appropriate to see. Create reverse cards when you need to learn knowledge in both directions. Or reverse an entire subject without duplicating the underlying material. A STUDY LOOP WITH AN OPINION - Typed production once a card is ready for it - New cards begin with recognition before harder recall is earned - Hints while you are still thinking - Immediate repair and retesting when recall breaks down - A Daily Review built around what actually needs attention - A new-card limit you control - Practise freely without disturbing the real schedule - Undo an answer made by accident - Independent scheduling for reverse cards SEE WHERE YOU ACTUALLY STAND See which cards are slipping and what needs attention now. See confusions Zynlo has genuinely observed rather than guessed. Check subject and deck health before weak material turns into weeks of wasted review. Progress figures are based on defined learning evidence rather than decorative scores. MADE FOR MORE THAN ONE LANGUAGE Zynlo's interface is available in: English French Turkish Italian Spanish German Hindi Arabic Urdu Arabic and Urdu include right-to-left support. Your own flashcards are never automatically translated or rewritten. PRIVATE, OFFLINE-FIRST AND YOURS Your study library lives on your device and works offline. Accounts are optional. Sign in with Apple, Google or email if you want a Zynlo account, while continuing to use the app without one. Your local cards, review history, typed answers and Notes & Images remain available without signing in. Export a complete Zynlo backup whenever you want, including supported images and learning history. Anonymous usage statistics can be switched off in the app. Zynlo is built for the part of learning that matters months later: being able to retrieve what you learned today.
