Time Controls for Memory

The Schedule Screen

One screen for everything that moves cards in time. The calendar shows how many cards land on each day of the coming weeks; below it sit four tools — Lighten, Study ahead, Days off and Rebuild — each with a live count of the cards it can act on. Pick one and the calendar redraws to show the result before anything is written, with today’s count as a before → after.

You’ll mostly arrive from the Learn tab. On a day with more than double your usual load, a small hint appears above the queue and opens the screen with Lighten already selected.

i

Shows only when today is more than double your usual load — one tap opens Lighten

iThe Learn badge is the same number the schedule tools work from

i

Every day carries its due count — today is 32, the rest of the month is what’s already scheduled

i

Live counts on the chips: 24 cards could be lightened, 16 could be studied ahead

i

Preview, not yet applied — today drops to 17 and the moved cards land on the days after

i32 → 17: the same change in one line, so you never count dotsi

New or still-learning cards have no schedule to move — the screen says so instead of hiding them

From the Learn hint to a previewed change — nothing is written yet

Lighten & Study ahead

Lighten moves cards that are due today to later days. Study ahead does the opposite: it pulls cards that aren’t due yet into today, which helps when a test is coming and waiting isn’t an option.

Neither asks you to type a number. There are three choices — Safest, Half, or All — and the panel shows what each one would do to your memory before anything happens. Not all cards cost the same to move, so the ones that can move almost for free go first. The ordering comes from the FSRS-Helper project, the same logic Anki users rely on.

i

Safest is computed per card — only the ones that can wait without a real recall hit

i

Predicted recall of the moved cards after the move — Safest keeps them in Good

iAll 24 — today goes from 32 to 8i

Push everything and the marker slides left — still Good here, but the cost shows before you confirm

Lighten — pick a size, see the recall cost, confirm

i

Safest picks only cards already close enough to due that reviewing today is On time

i

How well-timed today’s review would be for the pulled cards, from Wasted to On time

iAll 16 — today grows from 32 to 48i

Pull everything and the marker drops from On time to Good — the earlier a review, the less it is worth

Study ahead — pull future cards in, watch the timing

Days off

Tap your first day off on the calendar, then your last. Every card that would land in that window moves to the days after you return — spread over 3, 7 or 14 days so no single day gets buried, each card placed as close to its original date as possible. If the break starts today, the overdue backlog is swept along too, so you leave with a clean slate.

i

The range is picked on the calendar itself — no date pickers

iOpen-ended until you tap the last day; the button waits

i

The week is cleared and the following week picks up its 8 cards, about two a day

i

How many days to spread them over when you’re back — the calendar follows the choice

i

14 days: the same 8 cards thin out to one a day, Sep 14 – Sep 24

Days off — pause without the pile-up

Rebuild

The escape hatch. Rebuild replays your entire review history through FSRS and recalculates every due date from scratch — the same native reschedule that powers the desktop FSRS ecosystem. Changed your mind after lightening too much? This puts every card back where your actual history says it belongs. It only writes the cards whose dates actually change, and the calendar shows the new spread before you confirm.

i

The whole month redrawn from your logged reviews — today goes from 32 to 11

i

Only cards whose date actually changes are written — 40 here; new cards have no history to replay

Rebuild — every due date, recomputed from history
