Does the viewranger have the track up function on iPhone, where the map orientates itself

There’s an “Auto Rotate Map” feature which sounds like it might be just the thing?

Yep, saw that but not sure if you have to rotate the unit to
Ine up,with a compass in the corner

Hi, Ian at ViewRanger here – just to clarify on the iphone, you can have the map set to static ie always shows North Up or as mentioned by ormondroyd – Auto Rotate. The auto rotate will rotate the map round by 90degree changes to best show direction of travel as up the screen. In either mode you can choose to have a compass on the screen. The app works in portrait or landscape mode, depending on how it is held/mounted. I hope that helps. Cheers
