Very useful!
I installed it a long time ago, but it wasn’t since iPhone 12 that I was able to fully use it. I do a lot more hiking now. It’s perfect. You got the compass and flashlight right in the same spot. I don’t have to reach over with my finger or other hand. It also has access to a map, but it’s in a hidden menu. I like to see that in a icon visible and map to a allow offline downloads. I would pay more for more features. For now I guess we got what we got.
