I put our Subac tradition into an app — the macalin recites one ayah, you answer from memory. Free on Android.
Anyone who went through dugsi knows Subac — sitting in a circle with the macalin and the other students, going round turn by turn: he recites an ayah, and you recite the next one back from memory, with everyone listening. No screens, no shortcuts. That's how our parents and grandparents carried the Qur'an.
I'm a Qur'an student myself, and together with my teachers I built that exact experience into a free Android app called Tatbith (تثبيت — "to make firm"):
Subac mode: pick your reciter, open your portion — the sheikh recites an ayah, then your ayah appears hidden and you recite it from memory. Ayah by ayah, back and forth, just like going around the circle. Stuck? Reveal one word at a time, like a macalin quietly prompting you.
And around it, everything a hifdh student needs: a full 7-step session method (du'a → tikrar → listening → memorizing → anchoring → retention → muhasaba), a counted tikrar per ayah, a revision cycle so your old pages stay strong, and Mushaf-based progress tracking by page, juz and surah. Fully offline, no ads.
Our tradition kept the Qur'an alive for generations in those circles — long before any apps. I just want to make sure it survives ours.
