Memorization & Review

A page-by-page plan, review that brings back what you are about to forget before you forget it, and self-testing in three modes — one of them links verses to each other.

You need an account because your schedule is saved across your devices.

How to use this page — a full guide

Memorisation holds through review, not repetition in a single day. This page answers one question for you: when should I review each page I have memorised? It spaces reviews further apart as a page settles, and brings them closer when you stumble — so you neither review what needs no review, nor lose what is about to slip.

  1. ١ Open the “Add memorisation” tab and pick a surah you have memorised; its pages join your plan. The unit here is one page of the Mushaf, not a whole surah, because a page is an amount reviewable in one sitting.
  2. ٢ Each day the top shows how many pages are due today. Press “Start review” and they appear one by one. Only what is due appears, capped at twenty pages a day however much has piled up — so no day grows long, even after a week away.
  3. ٣ Recite the page from memory — the text is hidden in front of you — then press “Reveal” and compare what you recited with the Mushaf. Three test modes are explained below.
  4. ٤ Then choose one of the four ratings. This is not a score kept against you — it is what decides when the page comes back to you.
  5. ٥ The first three reviews are fixed: after one day, then three, then seven. After that the gap grows by a factor that rises as you master and falls as you stumble — weeks become months for what is firm. The plan shapes itself around your own memory, not a fixed timetable.

The three test modes — and how to choose

Three ways to test yourself on the same page, chosen from the bar above the text. Your choice is remembered for later sessions.

  • Hidden — the whole page is blurred and you recite it from memory. The hardest, and it suits what is already firm.
  • First two words — the first two words of each verse are shown and the rest is blurred. Gentler for beginning, and it exposes whoever knows a verse but not how it starts.
  • Linking — odd verses are shown and what lies between them is blurred, so you are tested on joining a verse to the next. This is where a memoriser most often breaks: he knows the verses separately and stalls at the transition.

What each rating means — and its effect on scheduling

  • Forgot — It returns tomorrow, and its spacing starts from zero.
  • Struggled — It returns after roughly two thirds of the previous gap, and does not count as a success, so it does not advance on the ladder.
  • Good — It advances on the ladder and spaces out at the usual rate.
  • Perfect — It advances and spaces out further than “good”, so what is firm does not take your time.

The four numbers at the top

  • Due today — how many pages have reached their review date. If any are past due, the overdue count appears beneath.
  • Pages in the plan — the total you have added, and its share of the Mushaf’s 604 pages.
  • Consecutive days — how many days in a row you reviewed something. One day without a review breaks it.
  • Average strength — an estimate from two things: how long a gap the page has reached (capped at sixty days) and how many successful reviews it has had (capped at six). It is an estimate, not a measurement, and its meaning is in how it moves, not in the number.

The look-alike alert — before you recite, not after

If the page contains a passage resembling another in the Mushaf, an alert appears before you begin, with both places side by side. Most of a memoriser’s confusion comes from look-alikes — and warning you before you recite serves better than correcting you after.

Common questions

I was away a week and much has piled up — what now?
No more than twenty pages are shown in a day however much has accumulated; the rest waits its turn. Review what is shown and do not burden yourself.
I added a whole surah but do not know all of it.
Remove what you have not memorised from the “My plan” tab — removal is by page, not by surah. Or rate it “forgot” so it returns daily until it settles.
Is my plan kept if I change device?
Yes — the plan is stored with your account, not in the browser, so you find it by signing in from any device. That is why this page requires an account and does not work for a guest.

Honesty with yourself in rating is all the plan needs to work. Rate yourself above your true state and it will space out what has not settled — so you lose it while believing it is kept.
