Study like you mean it.
A native iOS flashcard app built on real FSRS scheduling. Made for people who already know what SRS means and are tired of clunky UI and subscriptions.
One payment. No subscription. Ever.
Built for power users
Everything a serious deck deserves.
No onboarding quizzes, no streak mascots. Just the tools a real study system needs.
Real FSRS scheduling
