Training and the schedule

The five boxes, the review rhythm (1, 4, 12 and 35 days by default), and what counts as a review.

Kardamone schedules reviews with a system of boxes, known as the Leitner system: a card you know comes back later and later, a card you miss comes back tomorrow. You set the rhythm in Settings › Review rhythm: Standard by default, three other rhythms, or your own intervals.

The five boxes

Each card sits in a box from 1 to 5, separately in each direction: "France → Paris" and "Paris → France" are tracked separately.

A right answer moves the card up one box, to a maximum of 5. A wrong answer sends it straight back to box 1, however high it had climbed.

The next due date depends on the box reached, counted from the day you answered. These are the intervals of the Standard rhythm:

1. Box 1 — after a wrong answer, review tomorrow.
2. Box 2 — after the first right answer, review tomorrow.
3. Box 3 — review in 4 days.
4. Box 4 — review in 12 days.
5. Box 5 — review in 35 days. A card in box 5 is learnt. A right answer at this review makes it acquired: it comes back one last time 120 days later, then never again if you answer right; missed, it goes back to box 1.

The review rhythm

You choose the rhythm in Settings › Review rhythm. The boxes stay the same, only the intervals change, and a wrong answer always brings the card back the next day. Under each rhythm, a sentence says how many reviews it adds to or takes from your sessions.

Changing the rhythm moves no review already scheduled: the new intervals apply from your next answer. These are the intervals of boxes 2 to 5, then of the last check:

1. Standard (default) — 1, 4, 12 and 35 days, then 120 days.
2. J method — 1, 3, 7 and 21 days, then 60 days.
3. Intensive — 1, 2, 4 and 8 days, then 30 days.
4. Spaced — 2, 7, 21 and 60 days, then 180 days.
5. Custom — the five numbers you choose: each at least the one before, the first from 1 to 3 days, the last from 30 to 365.

What moves a card and what does not

Only written-test answers move a card between boxes and set its next due date — whether you typed the answer or used self-assessment.

Training does not touch the schedule: recognising an answer among four is not recalling it from memory.

Flashcards do not count at all: no box, no due date, nothing towards the daily goal.

The written test's "free practice" ignores due dates so you can revise what you like right now. It counts towards the daily goal, but changes neither boxes nor dates.

Reviews due

A card is due when its date arrives, and a card never seen is due as well. The number on the home page is the total due across your whole library; the one on a list page covers that list alone.

When a session tells you that you are up to date, it also tells you the date of the next scheduled review. Nothing stops you revising sooner: tick "Free practice".

Starting over

"Reset my progress", in the ⋮ menu on a list's own page, clears your boxes and due dates for that list only. The cards themselves are untouched, and so are your other lists.
