+xso I don't know what there is to discuss here. I buy a flying map, which should provide all information for the flight and planning.
If your requirement for a moving map system is to be the sole information source for a flight, you may be terribly wrong with Skydemon (and any other consumer-grade electronic navigational app).
Many times the Skydemon staff, and Tim Dawson here in particular, did emphasize that Skydemon is only a navigational aid, a supplement, and not a replacement for proper flight preparation!
I only point to the recent discussion on NOTAMs, the Q-line and the 'reminder style' depiction of Skydemon -> which only directs you which particular NOTAMs to read and does not claim to draw the NOTAM area itself.
It took me a while to accept the way Skydemon supplements my flight planning, to some extend because I would like to have it differently, but I see this is impossible on the little manpower and for such cheap price. I am absolutely fine with the construction of Skydemon, but after understanding what they do, I never rely a flight on the information from within the app alone.
