It would help with the memorization of new verses. The first time you successfully repeat a verse back you get a notification in half an hour to repeat it again, then an hour later you get another notification, then a day later, then a couple of days later, then a week later, then two weeks later, then a month later, and so on. People could set up their own routines with their memorized verses so that they could have reminders to revisit verses every month or so to test their memory.
