✦ Spaced Repetition

FSRS-5. The algorithm that actually works.

FORKSAI uses FSRS-5 — the most advanced open-source spaced repetition algorithm available. Cards are scheduled at mathematically optimal intervals based on how well you know each one.

1
Review a card and rate it Easy, Medium, or Hard
2
Easy cards are pushed further into the future
3
Hard cards come back after just 1 day
4
Your deck shrinks over time as cards move to long intervals
