Understanding FSRS and Scheduling Settings

Memo uses scheduling settings to decide when flashcards should come back for review. Advanced users can adjust FSRS-related values from Settings → Configuration → Scheduling.

What FSRS is

FSRS is a spaced-repetition scheduling system. Its goal is to show cards again at useful intervals so you review before forgetting, without reviewing everything too often.

Settings you may see

• Request retention: how strongly Memo should aim to keep cards remembered. Higher retention usually means more frequent reviews.

• Maximum interval: the longest allowed gap before a card can be scheduled again.

• Learning steps: short early review steps for new cards.

• Relearning steps: short steps used after you forget a card.

• Fuzz: adds slight variation so reviews are not scheduled too mechanically.

Should I change these?

Most users can keep the defaults. Change scheduling settings only if you understand the tradeoff between review load and retention.

Reset to defaults

If your review schedule starts to feel too aggressive or too light, use the reset option in scheduling settings to return to Memo's defaults.

Important notes

• Scheduling settings affect review behavior, not how flashcards are generated.

• Changing settings does not rewrite the content of existing flashcards.

• Learn Mode and Cram serve different purposes: Learn follows scheduled review, while Cram is a faster extra review session.
