Frequently Asked Questions
Quick answers before you start your first smarter study plan.
How does it work?
FSRS-6.0 tracks memory strength for each lecture. When you review and rate your recall, the system calculates the best day for your next review to hit your target retention (e.g., 90%). The algorithm is adaptive — it learns from your recall patterns and improves over time.
Why lectures instead of flashcards?
Creating flashcards is time-consuming. Instead, you add your lectures and focus on the actual material. No pressure to formulate questions or answers — just read, review, and rate your recall. Perfect for university students dealing with hundreds of lectures.
What if I miss a review?
Overdue items get highest priority. You'll see them at the top of your Study Session page, sorted by how overdue they are and how important they are.
What devices does it work on?
All devices! Desktop, mobile, tablet. The app works in your browser and can be installed as a Progressive Web App (PWA) for offline access.
Is it free?
Yes, Fakarny is completely free. We're students building this for ourselves — we added what we needed for exam prep and share it with you.
How accurate is the FSRS algorithm?
FSRS-6.0 is scientifically validated and open source. It outperforms traditional systems like SM-2 (used in Anki) by adapting to your individual learning patterns. Studies show it achieves higher retention with fewer reviews.
