User reviews

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.

Almost

The only significant attraction this app has over the others is the mobile phone coverage. But this is crowd sourced from their users, and they presumably have almost none of those in Australia cause there’s almost no such data, even in popular visitor locations like Gariweid (Grampians). So basically you’re paying to supply the app with data for no return at the moment.

Safety!

We had many deaths on the trails this year due to heat, no cell service, and a snake bite. I love that this app shows where cell service is available and notifies my family where I am.
