Rooted memorization, رسوخ
Guard the Qur'an you have memorized
Memorized Qur'an fades once review stops. Rusūkh tracks every portion you have learned, keeps a living estimate of its strength, and surfaces the weakening passages early, while they are still easy to restore.
A complete Qur'an reader for everyone, plus a memorization system you can try free.
Where hifz is lost
The hard part comes after you learn it
Most of us have memorized a sūrah more than once. The difficulty was never the memorizing. It is the erosion that begins the moment review stops, the slow loss of something you worked hard to hold. (Hifz here means memorization of the Qur'an.)
Memorized Qur'an does not announce its own decay. A passage you once held firmly begins to loosen, one āyah at a time, a verse here, a line there, often long before you notice. By the time a portion feels gone, the ground has already shifted. The effort you gave was real, and it deserves to be protected.
- Most hifz is lost long after the memorizing is done.
- A portion can weaken for weeks before you feel it.
- The effort you spent memorizing deserves to be protected.
The method
A disciplined method that protects your hifz
Rusūkh exists to help you keep what you have memorized. It tracks when each portion was last reviewed, keeps a living estimate of how firmly it is held, and watches for the early signs of weakening. When its estimate flags a passage as slipping, you see it clearly and early, so a short review is usually enough to set it right.
Instead of summoning discipline from nothing each day, you follow a structured rhythm of review that surfaces the weakest portions first. Your attention goes where it is needed, and nothing weakens without you seeing it.
- It tracks when each portion was last reviewed and how long it has been since.
- It continuously re-estimates the strength of every portion, so you always have a clear read on what is firm and what is fading.
- It surfaces the passages its estimate flags as weakening, so you can catch them early and a short review sets them right.
- Discipline becomes a daily structure you can follow.
Inside the app
See where your hifz stands
The Reading tab stays open to everyone. The Mushaf and Workspace tabs hold the memorization system: progress, strength, and the timing of each review.
How it works in the app
Built into the way you read and review
The Reading tab keeps the full Qur'anic text open to everyone. The Mushaf and Workspace tabs carry the memorization system: the strength tracking, the review scheduling, and the weakness detection that help protect what you have learned. Each part works together so your attention always goes where it matters most.
Continuous strength tracking
Every portion you memorize is watched, with a living estimate of how firmly it is held.
Early warning when an estimate weakens
When the estimate detects a portion slipping, it surfaces early, so you can revisit it before it slips further.
Review timed to each portion
Scheduling follows each portion's own estimated decay, so each one returns when it actually needs review.
Attention, guided
Your attention goes to the verses the estimate flags as needing it most, instead of guesswork.
An honest picture of your hifz
A clear, honest picture of your memorization, reviewed and updated as you go.
Reading and memorization together
The Reading, Mushaf, and Workspace tabs work as one, so what you read flows straight into review.

The meaning of the name
The name means rooted
Rusūkh (رسوخ) means firmness, depth, being deeply rooted and firmly established. It echoes the Qur'anic phrase ar-rāsikhūna fī al-ʿilm, those firmly grounded in knowledge. Rooted knowledge is what this app is built to protect: memorization that rests on a foundation you maintain. This is memorization that stays rooted.
وَالرَّاسِخُونَ فِي الْعِلْمِ يَقُولُونَ آمَنَّا بِهِ كُلٌّ مِّنْ عِندِ رَبِّنَا
"And those firmly grounded in knowledge say, We believe in it; all is from our Lord."
Sūrah Āl ʿImrān 3:7
