I promised I would test it and comment

For what I use it for, so off-trail, definitely a great thing, as it shows the terrain very well. Paths (closure) doesn't interest me, I can check that elsewhere

Ok, for the biggest zoom it's obviously necessary to have the premium version, but even one level less shows well.
I notice though that when planning routes errors often occur and it spits out a hugely exaggerated number (kilometers and time). Probably a problem with some formula in the calculation? I don't know, I'm guessing, I'm not a programmer

And one more thing, often there's an error with the location of the peak/summit, that it's not exactly where it should be. But that's probably just a copied error from openstreetmap, because those errors are also quite common there.
