Why spacing works

Projected recall across your decks over 30 days: reviewing on schedule (green) versus never reviewing again (amber), at your target retention.

Performance

Your memory, measured — every indicator derived from the DSR model and your own review history
Grounded in science. These numbers come straight from the memory model — retrievability R(t)=(1+19/81·t/S)−0.5, stability S and difficulty D updated on every review. Nothing here is estimated or faked; it is your real study signal.

Reviews per day

Your retrieval volume over the last 30 days.

Stability distribution

How firmly your cards are held — stability is days until recall falls to ~90%.

Rating mix

How you've graded recall — the balance of Again / Hard / Good / Easy.

Maturity

Share of your cards that are new, learning and mature.

By deck

Per-deck breakdown of size, maturity, due load and average stability.
