Lack of offline maps are a showstopper for using the new Apple Watch Ultra for multi-day hiking. This post tests the only workaround against Garmin Fenix.
Here's a counterpoint. If I actually want to look at a map, I look at my phone or a paper map. I find squinting at a map on a watch way too small to be useful. The apps I've used on both Garmins and the Apple Watch have a map screen that I basically never use.
