Alltrails works around the world, and outside of national parks, so not really rivalling....
I was hiking in Yosemite, about 2 or 3 days from the trailhead. There is zero cell service there, even at the trailhead I was by myself. The trail mostly followed a river. Then I meet these two girls (OK I'm an old guy so everyone only 40 looks young, they were likely in their 20s so clearly "born in the digital age")
One of them shows me her iPhone which has a map and a blinking "you are here" dot. And she asks me "Where are we?" Clearly, she knew the blinking dot was the location and that she was standing on a trail but she meant, is it a hard or easy walk to a place to camp, will the canyon open up and get wider, and how long of a walk is that? All this was clearly on her map but all she was seeing was a useless-to-her "you are here".
Think about it, if you can't read a topo map, the "you are here" dot is as useless as if you drew an "X" on the ground and I told you "You are standing on an "X". You are always "here" no matter where you go and the GPS will always uselessly tell you that you are standing in the place you are standing. Seriously all she saw was a screen filled with usless wiggly lines and a flashing dot. She could also see the direction she needs to walk.
I think this is a problem with people who depend on these electronic gadgets, You don't need "turn by turn" directions when the plan is to walk for two days on the same trail.
Because of these electronic maps, there are now maybe as many people like this with zero map-reading skills. Maybe this is an opportunity for Apple or someone else to apply AI to topo map reading. You could ask the AI "when will we come to the next good place to stop for lunch and a rest with a flat space by the water? The system then makes a custom graphic.
(let's not talk about what happens if you are 20 miles from the road and you drop your phone in the water and can't read maps and don't own a compass.)
