Review
An absolute must-have app for solo hikers. The automatic notification system gives my family so much peace of mind because they know they'll be alerted with my last known GPS location if I'm overdue coming off the trail. I especially love the crowdsourced cell coverage mapping feature—it makes finding a signal patch in the middle of nowhere so much easier. The offline maps are clear, reliable, and don't completely kill my battery. Highly recommended

Perfect for More than Hiking
I downloaded this app for hiking and tracking my path. I realized it is great for sharing your location with family and friends too. It will allow for tracking. You can also download a map of the place you are going to plan out your path.
Used Carin for years
I’ve used this app for I think about five years, all four seasons. Whether I’m hiking in the summer with my dog or splitboarding in the winter, this app has been awesome. I love being able to track my roots, elevation gain and time. highly recommend for any outdoor enthusiast.
Love the Cairn app!
I have a history of a heart attack so the feature that lets my loved ones know about my travel plans is really helpful
Failed in the middle of hike
Such a great idea so I decided to try this app out. Unfortunately, it just stopped tracking me in the middle of my Grand Canyon rim2rim hike. Not sure why this happened since I never let my battery die. I guess it was too good to be true. Subscription ended.
