Hashcards is a free spaced repetition scheduler app that helps you remember what you study. No subscription. No account required. Works completely offline. Just open it and start learning.

Most flashcard apps either charge you monthly, force you to create an account, or use outdated algorithms that waste your time. Hashcards is different. It uses FSRS — the latest advanced spaced repetition algorithm available — to schedule your reviews at exactly the right moment. You study less and remember more.

✨ Why Students Choose Hashcards
Hashcards was built for people who are serious about learning but tired of apps that get in the way. Whether you're preparing for medical exams, learning a new language, or studying math-heavy material, Hashcards adapts to how your memory works and helps you retain knowledge long-term.

🧠 What Is FSRS?

FSRS (Free Spaced Repetition Scheduler) is a research-backed algorithm that learns how your memory works. Unlike older scheduling systems, FSRS adapts to your individual forgetting patterns and schedules each review at the optimal moment. You spend less time reviewing and retain more.

🔢 The Only Flashcard App with a Math Keyboard

Most flashcard apps treat math as an afterthought. Hashcards has a built-in math keyboard so you can create flashcards with equations, integrals, matrices, and chemical formulas — no workarounds needed. If you study anything with formulas, this changes everything.

✈️ Truly Offline

Many popular flashcard apps require an internet connection. Hashcards works completely offline. Your flashcards live on your device. Study anywhere — no Wi-Fi needed, no cloud dependency, no sync issues.

🆚 Spaced Repetition Without the Complexity

Other spaced repetition tools are powerful but overwhelming — steep learning curves, complicated setups, and plugins. Hashcards gives you the same advanced algorithm with a clean, modern interface anyone can use from day one. No plugins, no desktop app, no configuration.
