I know this isn't directly an answer, but I live in Utah and find that mapping on a device is not reliable in some of the parks, and definitely not out in the wilderness. The cell network just isn't 100%, and unless your device has a satellite-based GPS, your mapping won't work anyway.
I do agree that better apps are needed. I'm an avid explorer of Utah's western desert, and even with both paper maps and electronic, and prepping by looking at what Google maps thinks is correct and reviewing satellite imagery before I go, the patchwork of old abandoned dirt roads out there is still a maze much of the time.
The point being... when going out into the wilderness, even with a good app, please don't rely on it 100%. Plan well and be safe.
