Surahs
One Surah at a time, Thabbit will help you achieve your goal of becoming a Hafidth.
Juz
With 30 Juz to choose from, Thabbit can accommodate users at any stage of their memorization.
Pages
Thabbit uses the classical Madani script for a consistent, universal experience.
Mutashabihāt
Thabbit tests all the possible mutashabihāt (similar verses) to minimize mix-ups.

Thabbit implements uniquely tailored spaced-repetition algorithms that break down the Mushaf into individual pages as testable units. As time progresses, the user is able to:
Instantly recite a page when prompted with the page number.
Instantly recall the page number when prompted with any page or verse in the Mushaf.
Be aware of and easily differentiate between the various Mutashabihat found across the same Surah as well as different Surahs.
Enhance their motivation to continue perfecting memorization.
