Nice update

I am mostly interested in this app to plan backcountry ski tours and the last update fixed the glitches when downloading terrain and slope gradient layers. It’s pretty neat to be able to pan around in 3D with the slope gradient overlay. It would be even better with slope data over the topo layer similiar to caltopo.

Hey Woodave-

We actually just pushed a fix for this, I'd love to get your feedback on the app as a whole as I actually spend quite a bit of time at BP as well.

Good start but needs route discovery

I use Gaia Maps and Maplets (and Google Maps)- all these apps serve a distinct purpose. Unfortunately, this app does deserve the phone memory. On an iPhone SE the UI is a little choppy. This app is like Google Earth, it doesn’t really add any value beyond that for me. And being old fashioned, 2D topo maps are just fine to use when exploring outside.

So what does this app need? I could see something like this being popular once AR is more widespread, but what it’s missing is everything else needed in backcountry navigation like layer support, trail names, route tracking, the ability the effortlessly find new trails.

Some easy fixes would help

I use it to orient myself to new ski areas before I arrive or maybe after a day or two, and it can be great for that. One huge annoyance: when you press a ski run to see its name and get info, the entire view reorients itself - I guess so you can see the entire run from an angle the developers like. Super annoying to have to re-orient the map manually each time I highlight a run. Makes me afraid to highlight a run at all Please fix this!

Developer Response ,

Hi, thanks for your message! This has now been updated in the app, so that when you click another run, the camera doesn't change position. Please try it out and let us know what you think!
