All Trails is a terrible app for a couple of reasons. The most important one is that All Trails is significantly wrong on many of the distances it posts for various trails. This is not only frustrating, it could also become dangerous. The app is not very descriptive, and uses the same boring, repetitive template for every trail, with just a little info specific to a particular trail. My sister and I hiked in Sedona for 3 weeks, and after about the 3rd hike with inaccurate distances and very little specific information, we quit using All Trails altogether. We use Gaia instead, very happy with it.
