Windy maps fails to show some small trails that are visible on Open Streetmaps, Open Cyclemaps, Viewranger and even Windy.com weather. This is critical for trailfinding. I love the auto-routing function on this app, but I will switch over to Viewranger because missing trails means added walking.
I also found Offline Maps to be very lacking in resolution/scale, when you try to zoom down to the trail level there's nothing there, it only shows a zoomed out level that is just too far out to be useful in trail navigation. Again, Viewranger beats it squarely on that score.
