Both my previous handheld devices (Lowrance and Garmin) in track up mode did precisely that - even the smallest course correction resulted in a small rotation of the map. The ownship icon remained strictly pointing up.

Skydemon appears to implement a 'track nearly up' option instead - resulting in the track being often a few degrees either side of straight ahead - and also in the map only moving periodically to reflect movement along track. I assume this is a design feature to improve performance rather than redraw the map constantly on slower devices.

Is there a way to get a true 'track up' display? If not, I might request it in a future release...

I may, of course, just get used to it!

SkyDemon only redraws the map once you've changed by X degrees, for performance reasons. It's one of many things we do to make SkyDemon kinder to your battery than other apps. We have no plans to make X configurable; it's never as much as 45 degrees and is actually 15 degrees on modern phones and tablets.
