Spaced repetition method
The brain forgets information along a specific curve. Spaced repetition uses this law.
Review before you forget — and you'll remember forever.
How the forgetting curve works
- •After 1 hour — you forget 50%
- •After 1 day — 70%
- •After 1 week — 90%
Spaced repetition "resets" the forgetting curve with each review.
90%
Of information is forgotten within a week without review
In Lisn, spaced repetition is built in automatically — the app reminds you.
