Quick shoutout for Trail Sense for Android. Designed to function offline, lots of cool navigation/basic tools I haven't used outside of the GPS and compass, reasonable permissions, etc. One of those "You don't know how useful it is until you don't have connectivity" things.
Excellent! I tried a couple trail apps for iPhone without any luck - they didn’t have local trails or cost too much for how occasionally I’d use it. Lately I have been doing short local hikes on well marked trails, so it’s not really a need
google also allows offline caching, but also needs to be set up ahead of time. AFAIK once you set a region to download, it will update that cache regularly.
I would expect this is a feature that most map apps would offer
Following the gps map- is great when you’re trying to get somewhere, but if the goal is walking, I usually want to leave the tech in my pocket. Compass is a nice compromise to help navigate while still taking a break from behind slave to the machine
