Just used this app in Platoro, Colorado with my family for a week. Amazing accuracy. The trail was difficult to see in a few areas so when I opened up iHikeGPS it showed us where we were in relation to the trail. We were only about 25 feet off course to the right. We were able to easily get back on course. Elevation and distance traveled was a lot of fun to keep track of.
