I recently discovered that a student pilot was using Skydemon to make up his Plog. The simple (!) acts of deciding what route to fly, measuring the track angle and distance on a chart, applying wind corrections manually (whether mental DR or using the whizz wheel), preparing and studying the chart etc are essential building blocks in learning how to navigate.
Once these steps have been mastered including how to navigate whilst airborne then and only then is it acceptable to start using other devices to assist the task.
