Everything in one app

Built for the way pre-meds actually study

The proven spaced-repetition workflow, rebuilt as a fast, beautiful native app for iPhone and iPad.

Proven spaced repetition

An SM-2 scheduler shows each card right before you'd forget it — so you remember more in less time. Again / Hard / Good / Easy, just like you're used to.

Bring your own Anki decks

Import the .apkg decks you already use. Synapse rebuilds the subject and chapter hierarchy, renders images and LaTeX, and keeps your cloze cards intact.

Apple Pencil scratchpad

Work physics and chem problems right beside the card. The scratchpad clears between cards so your reasoning stays with the question it belongs to.

Insightful analytics

See 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. Open and read 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.

On-device AI

A study coach that runs entirely on your iPhone

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. The coach 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. No connection required — coaching is right there during a study session.

What should I focus on this week?

Frequently asked

Can I use my AnKing or MileDown deck?

Yes. Synapse imports standard Anki .apkg files that you already own — just export your deck (with “Support older Anki versions” enabled) and open it in Synapse. We don't redistribute third-party decks; you bring your own.

Is the AI coaching private?

Completely. The coach runs on-device using Apple Intelligence. Your study history is never uploaded — there are no servers and no account. It also works offline.

Does my data sync between iPhone and iPad?

Yes — your decks, cards, and progress sync automatically through your private iCloud account. There's nothing to set up beyond being signed into iCloud.

What devices do I need?

Synapse is a universal app for iPhone and iPad. The on-device AI coach requires a device that supports Apple Intelligence; everything else works without it.
