Smart memorisation (Hifz)

Essiraj's hifz engine uses spaced repetition (SRS) adapted to Qur'an: each ayah you mark as memorised is scheduled for review at the optimal moment. Build up your hifz one ayah at a time, run daily reviews, and watch progress accumulate per surah, per juz and per page. Specialised exercises — cloze deletion, first-letter prompts, elaborative recall — train deep memory, not surface recognition.

  • Spaced-repetition scheduling (SM-2 inspired, tuned for Qur'an)
  • Cloze, first-letter, elaborative and interleaved exercises
  • Progress per ayah · per surah · per juz · per page
  • Daily review queue that adapts to your pace
  • Guided hifz mode with audio scaffolding
  • Exam mode for formal hifz testing
  • Quiet mode for silent practice in public

    Each morning, Essiraj shows the ayahs the SRS chose for review — typically 5-15 minutes.

FAQ

Questions about this feature

How does spaced repetition work for the Qur'an?

Each ayah you mark as memorised enters a review queue. The algorithm (SM-2 inspired) schedules the next review at the optimal time — a day, a week, a month later — so the ayah transitions into long-term memory with minimal effort.

What exercises does Essiraj offer?

Cloze deletion (fill the blank), first-letter prompts, elaborative recall (explain the meaning), interleaved practice, tajwid drills and ordering exercises.

Can I track my hifz progress?

Yes — per ayah, per surah, per juz and per page. The app also shows your daily review compliance and streak.
