I would like to be notified for tahajud but maybe have 2 options like one to wake up two-thirds of the night and one to wake up 1 hour before fajr to help those have difficulty getting up for two thirds of the night. I unfortunately, have difficulty getting up to an alarm to wake up 2/3 of the night as the gaps between fajr and tahajud tend to differ so 1 hour before would be nice.
