I have recently started using Gaia and I love it. I mark out my route on it before leaving, put my phone on airplane mode and battery saver to reserve power, and still the accuracy of where I am is amazing. It makes getting back on track if you have veered the wrong way so quick and easy.
The first time I used it I was on a hike in Vic Alps and I had not preloaded anything before switching to airplane mode. I also wasn’t a subscriber then and was using the free version. We decided to do a side strip and I was able to navigate us to the correct path using Gaia.
And of course having a hardcopy map just in case the phone fails.
