Modern FSRS scheduling, flawless Anki & Quizlet import, and automatic local backups. Your cards can never be taken from you — and you pay once.
Quizlet paywalls studying your own sets. Knowt charges $150 mid-exam-season. AnkiMobile is great scheduling wrapped in fifteen-year-old UX. Slap Card is the missing middle: modern, one-time, and data-safe.
Tired of ads between cards and a wall in front of sets you made yourself.
Surprise $95–150 charges the week before an exam. Never again.
Love the algorithm, hate the decade-old interface and deck-eating sync.
The modern open spaced-repetition algorithm. Four ratings, smart intervals, zero setup to start.
Anki .apkg, Quizlet exports, and CSV/TSV — scheduling and structure preserved.
Automatic daily local backups. Restore and export are free forever — even on the free tier.
Set a date and the scheduler compresses intervals so you peak right on exam day.
Review heatmap, retention, a 7-day forecast, and a gentle streak — no guilt-trip notifications.
Turn notes into cards on-device. Every generated card is shown for your review before it saves.
Studying should feel good. Flip a card with a tap, rate it with a satisfying haptic, and watch the interval update live.
Your streak headlines the home screen. Stats celebrate the work — retention, reviews, a GitHub-style heatmap, and badges you actually earn.
No subscriptions. No ads. No "your trial is ending" emails. Try it free, then unlock everything once.
Free tier: 3 decks & 200 cards, full FSRS, full import preview, free backups.
Yes. One purchase of $24.99 unlocks Slap Card Pro forever, with Family Sharing. There are no subscriptions and no ads, ever.
Automatic local backups, restore, and full export (CSV + your cards) are never gated — not even on the free tier, not even at the limit. Your data is yours, and that's unconditional.
Yes. Import Anki .apkg files (with scheduling state and structure preserved), Quizlet exports, and CSV/TSV with a column mapper. You always see a full preview before anything commits.
Free includes 3 decks and 200 cards with the full FSRS scheduler, study, stats, import preview, and free backups. Pro removes the limits and adds AI drafts, custom themes, card images, and exam mode on every deck.
Completely. Slap Card is local-first — no account, no server required. Everything lives on your device.
FSRS (the Free Spaced Repetition Scheduler), the modern open algorithm that adapts to how you actually remember — more efficient than the classic SM-2.
Spaced repetition that's fast, tactile, and pay-once.
