How review works

Step 01

Practise as normal

Every question you attempt becomes a card. The ones you get wrong are flagged to come back soon.

Step 02

FSRS schedules it

The modern algorithm predicts the exact day you're about to forget, and books the review for then.

Step 03

Review, rate, repeat

Answer, see the worked solution, and rate how it felt. Nothing you fix slips before exam day.

Built to make it stick

Not a plain flashcard app. A scheduler that models your memory and fits your exam window.

Expanding intervals

Get a card right and it drifts weeks, then months into the future. Miss it and it comes back tomorrow.

Tuned to your exam date

Intervals are capped at your sitting, so every card is reviewed at least once before you walk in.

Review forecastExam day

Nothing scheduled past your sitting.
