Beat the forgetting curve.
Science sets the schedule.
Finished a session? Add it to your Review list with one click,
and Ritsu spaces each part out on a proven 1–3–7–16–35-day plan —
with a due count waiting the next time you open up.
The core move
You add it once.
Ritsu handles the timing.
You decide what's worth keeping. Ritsu decides when to bring it back.
- Beat 1
One click, when you’ve finished something.
- Beat 2
Ritsu spaces them out on a proven plan.
- Beat 3
And a due count is waiting when you come back.
The gap
The problem isn’t learning it.
It’s still knowing it next week.
The leak
It fades on a schedule
Most of what you learn fades within days — that part's just how memory works, and no amount of willpower changes the shape of the curve. The fix is old and proven: revisit it, spaced out over time. The catch is the next trap.
The miss
Hand timing misses both ways
Doing the spacing by hand is a mess. Review too soon and you waste effort on what's still fresh; too late and it's already gone — and with a dozen things in flight, you never quite remember which one is due when.
You shouldn't have to hold the timetable in the same head that's trying to hold the material. That timing is exactly what a schedule is for.
The schedule
A schedule that adapts to how well you actually remember.
Each thing you review moves along a ladder of widening gaps — a day, then three, then a week, then more.

“The Calvin cycle” sits in box 2 — its next review comes in 3 days.
Nail a review and it steps up a rung, so it comes back less often. Struggle and it drops back, returning sooner, until it sticks. You're never quizzed on what you clearly know, or left to forget what you don't.
What a review is
Every review makes you recall it, not re-read it.
A review isn't skimming your notes again. Ritsu builds it from your own material — and you leave having used the memory, which is the whole point.
Step 1 · Recall
A cue, not the answer
Step 2 · Check
A quick quiz
Step 3 · Explain
Written, then graded
Get one wrong and it comes back around before you finish. Every screen is built fresh from what you studied — no cards to make, nothing to look up.
Anything worth keeping
Finish it, decide it's worth keeping, and it's on the schedule.
Every review is built fresh from what you actually studied — first turn a source into a session, work through it, then add it — from there the timing is Ritsu's job.
Questions
What people ask before they add their first session.
You'll see a due count in Ritsu the next time you open it — a badge on your Review list. It doesn't send push notifications or emails; the schedule is waiting for you inside the app.
Learn it once. Keep it for good.
Finish a session, add it to Review, and let the schedule do the remembering.
