Synapse
Read full descriptionHide full description
Study anything. Remember everything. Synapse is a fast, native flashcard app for learning anything — 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 — 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 — 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 — 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 — 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 — Keep your PDFs, notes, and reference docs in nested folders right next to your decks, and read them without leaving the app. • iCloud sync — Study on iPad at home and review on iPhone between classes. Your decks and progress sync automatically through your private iCloud — no account to create. STUDY ANYTHING Synapse started as an MCAT tool and still excels at it — 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 — what to review next, which subjects are slipping, and how your progress looks. Ask it anything about your decks. • Grounded in your data — it only talks about your real subjects and progress; it won't invent topics or facts. • Private by design — the model runs on-device. Your study history never leaves your iPhone or iPad. No servers, no accounts. • Works offline — 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 — we never see them.

Tired of replaying conversations in your head hours later? Going quiet in meetings when you had something to say? Rehearsing a simple phone call before you dare to make it? ComposedAI is a private place to practice. Talk through real situations with an AI coach, hear how you actually sound, and build the kind of calm that comes from practice, not pep talks. PRACTICE REAL CONVERSATIONS Roleplay the moments that trip you up: job interviews, speaking up in meetings, small talk with someone new, difficult conversations you keep putting off. The AI plays the other person, responds to what you actually say, and afterward gives you honest feedback on what went well and what to try next time. HEAR HOW YOU ACTUALLY SOUND Record yourself speaking and get a real breakdown: pace, pauses, filler words, confidence, and fluency, with specific coaching on what to work on next. No vague grades. You see exactly what you did and how to improve it. BUILD A WORDBANK YOU ACTUALLY USE Save words and phrases you wish you used more, from a catalog of 500 or your own. Practice each one by saying it in a sentence and then answering two real situations with it, out loud. A word is yours once you have used it, not once you have read it. LEARN THE SKILLS IN SHORT LESSONS Every lesson in order, module by module: starting conversations, keeping them going, thinking on your feet, staying composed under pressure, handling hard conversations. Each lesson takes a few minutes and ends with something you can use the same day. BUILD THE HABIT • Daily Take: a one-minute spoken answer to a fresh prompt, four practice categories • Streaks, XP, levels, and streak freezes, so a missed day does not erase the month • Daily reminders you control, at the time you pick WHO THIS IS FOR • You avoid speaking up even when you know the answer • You dread being put on the spot • Interviews, meetings, and networking drain you • You feel like everyone else got a social handbook you never received ComposedAI is not about commanding the room or becoming someone you're not. It's relief: walking into a conversation without the knot in your stomach, saying the thing you meant to say, and leaving without replaying it all night. Practice in private, where the stakes are zero, so the real moments feel familiar. SUBSCRIPTION ComposedAI requires a subscription. Choose yearly with a 7-day free trial, monthly, or weekly. Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel anytime in your Apple Account settings.
