I bought an Apple Watch Ultra and was hoping to use it for route finding or get a glance of trails since it's so clunky to bring your phone out on the bike and the watch is just on your wrist, but I was disappointed to know there was no Trailforks app for it, so my buddy and I put together an app and used it quite a bit for skiing too. Let me know what you guys think, it has a bunch of backcountry trails and single tracks from OSM and you can upload from iPhone your trailfork gpx files too. It's not perfect but does the job!
