Best Outdoor and Hiking App Ever!!!

This is a must for outdoor safety. I've been using it for about a year now on hikes, bikes, ski,and trail runs. Well designed and thought out app. I found it user friendly and my mom likes to receive cairns notifying her of my next hike and location status, my safety contacts don't even need the app to track me. While on the trail Cairn shows you the distance left, elevation gain, and ETA. Also where there is cell coverage on offline maps in case you need help or just want to send a text. One of the best app values since the app is free, they don't charge for topo downloads and it's become my budget Spot With I'm ok and other updates. Recommend this to all hikers, outdoor enthusiasts, and worried parents.
