Synapse
Read full descriptionHide full description
Study anything. Remember everything. Synapse is a fast, native flashcard app for learning anything ā built around proven spaced repetition, so it shows you each card right before you'd forget it and you remember more in less time. Create your own decks or import the ones you already use, sketch with Apple Pencil, and get private AI coaching that knows exactly where you're struggling. WHY SYNAPSE ⢠Modern spaced repetition ā Synapse uses FSRS, a modern open-source memory model, to schedule each card just before you'd forget it. Grade every card Again, Hard, Good, or Easy and Synapse handles the rest. Prefer the classic SM-2 algorithm? Switch any time in Settings. ⢠Bring your own decks ā Import the .apkg flashcard decks you already own. Synapse rebuilds the subject and chapter hierarchy and renders images, LaTeX, and cloze deletions. ⢠Apple Pencil scratchpad ā Work physics and chemistry problems right beside the card. The scratchpad clears between cards, so your reasoning stays with the question it belongs to. ⢠Insightful analytics ā See your reviews over time, filter by range, and tap any subject to drill in. Spot the topics slipping before they cost you points. ⢠Resource library ā Keep your PDFs, notes, and reference docs in nested folders right next to your decks, and read them without leaving the app. ⢠iCloud sync ā Study on iPad at home and review on iPhone between classes. Your decks and progress sync automatically through your private iCloud ā no account to create. STUDY ANYTHING Synapse started as an MCAT tool and still excels at it ā but you can build decks for whatever you need to learn: med-school boards, anatomy, pharmacology, histology, nursing, the bar exam, the GRE, languages like Spanish, music theory, and more. If it fits on a flashcard, you can learn it here. A STUDY COACH THAT RUNS ON YOUR DEVICE Synapse uses Apple Intelligence to turn your own study data into real guidance ā what to review next, which subjects are slipping, and how your progress looks. Ask it anything about your decks. ⢠Grounded in your data ā it only talks about your real subjects and progress; it won't invent topics or facts. ⢠Private by design ā the model runs on-device. Your study history never leaves your iPhone or iPad. No servers, no accounts. ⢠Works offline ā coaching is right there during a study session. PRIVATE BY DEFAULT No ads. No tracking. No account. Your decks, cards, and progress live on your device and sync through your own private iCloud ā we never see them.
