The problem
Without recall, 70% of a course is gone in 48 hours — your brain sorts as it goes.
Ebbinghaus measured it back in 1885: memory drops off exponentially. Every spaced recall flattens the curve — the trick is revising the right card at the right moment. That is exactly what Memojin computes.
FSRS, named and owned
Every card gets its own schedule from your past answers — 20 to 30% fewer reviews, for the same retention. A measured property of the algorithm, until our own data says otherwise.
Deterministic, not a black box
Choosing the cards and computing the intervals is a calculation applied to YOUR answers — no AI model takes part in those decisions.
Memoboost: never a random pile
Cards tied to a nearby exam first, then overdue ones, then today's.
15 minutes a day is enough
Well placed, they beat the all-nighter before the exam.
In the app
Today's recall
Each morning Memoboost assembles the pile: the nearest exam first, then overdue cards, then today's — neither too early (pointless) nor too late (forgotten). The link with Exam mode is direct.
