The science behind Loci
You forget 70% in 24 hours.
Ebbinghaus's Forgetting Curve shows that without review, your brain discards most of what you learned in a day. Spaced repetition interrupts this — by reviewing at the exact moment you're about to forget.
Loci uses SM-2 to calculate when each card should come back. Got it right? Longer interval. Got it wrong? Immediate reinforcement. Maximum retention, minimum effort.
