Active Recall Deck
Cards drawn from all thirteen lessons and all seven feature tours, scheduled with SM-2 — the same spaced-repetition algorithm your own flashcard feature implements. Answer honestly; grading yourself generously just means you see the card less when you need it more.
How the scheduling works — and why it's the same as your app's
Each card carries three values: an ease factor (how easy you find it, starting at 2.5), an interval in days, and a repetition count. You grade yourself 0–5; anything below 3 is a lapse.
On a lapse the repetition count resets to zero and the card comes back in a day. On a pass the interval steps 1 day, then 6 days, then previous interval × ease factor. The ease factor itself drifts up when you find cards easy and down when you don't, with a floor of 1.3 so a difficult card can't spiral into being shown every few minutes forever.
That floor is the detail worth remembering — it's the difference between an algorithm that degrades gracefully and one that punishes you for having a hard card.
Progress is stored in localStorage under the same key as your lesson
progress, so clearing site data resets both. Nothing leaves your machine.
