The schedule
Every time you remember a card, Ruled waits longer before showing it again. Grade it Good seven times and it comes back after 1 day, 6 days, then 15, 38, 95, 238 and 595. That's seven reviews across nearly three years. Forget it once and it starts again tomorrow, so you relearn it before it slips.
How it works
Type cards in, front and back, with line breaks kept. Or import a CSV from a spreadsheet or a classmate.
Open Ruled once a day. See the front, recall, show the answer, grade it. Space and keys 1 to 4 do it all.
Each grade sets the card's next date with SM-2. Cards you know drift away; cards you miss come back tomorrow.
What's in the box
Today shows what's due in each deck. The longest-overdue cards come first, and Review all runs every deck in one session.
At most 20 new cards per deck a day, so a 2,000-word import arrives a little at a time.
Each button tells you when the card would come back before you press it.
Import any CSV with front and back columns. Export keeps every card's schedule, so a backup brings your progress back exactly.
No account and no server. Your decks live in this browser's storage, and nothing is sent anywhere.
Space to show, 1 to 4 to grade. Focus never gets lost, and every save is announced.
Light and dark follow your system. With reduced motion on, the card just appears instead of flipping.
The real thing
It runs right here, the same as at app/index.html. Anything you make is saved in your browser and will be waiting when you open Ruled.
