my current routine, not pretty but it works
fajr i sit for new memorization. only half a page, sometimes less if my brain isn't there. then on the walk back from the masjid i revise yesterday's page out loud. after isha i do old revision, usually the last juz i finished, just reading from memory in salah or pacing my room.
what's working: doing new hifdh right after fajr. nothing competes with it yet.
what's not: my old revision is a mess. i built an app for this (i'm the founder of SABR: Quran Memorization) and even i skip it some nights. honest truth.
