it may depend on the particular map and the data they have on it. I would think that the data from the phone app and the map card would come from the same source but who knows.
I just took a look at a lake by my cabin, the phone app and the paper map I have are just about identical.
I do have the Navionics map on my chartplotter on my big boat but its at the cabin and I am at home so I cant compare it to the others right now
