See exactly how Recka schedules
No hand-waving. Every demo below runs the same scheduler the app ships with, right here in your browser. Change the numbers and watch what Recka would actually do with your cards.
The forgetting curve, and how reviews bend it
Every card has a memory that decays over time. Recka's FSRS scheduler models that decay for each card and shows it to you right as recall is about to slip below your target. Rate the card and watch each success lengthen the next interval. This is the real thing, not decades-old SM-2.
The recall you want to hold. Aim higher and Recka reviews you sooner and more often; aim lower for fewer reviews and a little more forgetting.
Exam Sprint, so nothing peaks too early or too late
Normal scheduling is built for the long run, so a card you know well might not come back until weeks after your exam. That is fine in June and useless the week of a test. Set an exam date and Recka caps every interval at a quarter of the days left, so each card keeps resurfacing and lands on exam morning still fresh. Drag the date closer and watch the two schedules pull apart.
Set a date and Recka aims every review at it, tightening the schedule as the day gets closer.
The recall you want to hold day to day, before the sprint pulls the last stretch even tighter.
Left alone, this card would not resurface until 53 days after your exam. You would walk in never having seen it again. Exam Sprint caps each interval at a quarter of the days left, so the card keeps coming back and lands on the morning of the exam still fresh, weakest and highest-yield cards first. Set it on a folder and every deck inside inherits the same date.
Same interval-cap math the app runs when a deck or folder has an exam date set.
Rescue Mode, instead of an avalanche
Miss a few days and most apps greet you with a wall of hundreds of overdue cards. Recka spreads that backlog across the days you actually have, weakest cards first, so no single day becomes the next cliff. Drag the sliders to feel it flatten.
today
Weakest cards (most lapses, lowest ease) come back first, so the day you return you meet the cards you're shakiest on while they still matter most. Change your mind and get time back? One tap pulls everything you haven't reviewed yet straight back to today, and keeps the ones you have.
