Customer Reviews

Does not work with Apple Watch 3 GPS

I just spent four days in Zion Park hiking and was excited to use the app. Do not download or use this app. The mileage and elevation tracking are grossly off. For a 7-mike hike, the app recorded 20.8 miles! For 1,400 feet in elevation gain, it recorded 2,800 feet in gain. I contacted Trails support, sent both days worth of tracking data from their app and they simply said they cannot resolve and told me to request a refund from the Apple App Store. I wrote this I hoped that it might save someone the trouble I just went through as well as the disappointment of not being able to track a few epic hikes.

UPDATE: Trails responded to my reviewing claiming I did erratic zig zagging causing the error. Any person who hikes inclines at altitude knows this is the norm - they’re called switchbacks. If an app cannot track someone cl moving switchbacks then it should never claim to be a Trails app.

Absolutely THE BEST tracking app

I rarely write reviews but I love this app. It works perfectly for what I do (hiking and kayaking). I love the features! I can map, the stats are awesome, I can take a picture and see exactly where on the map it was taken, it auto turns off when I get back to where I started so I don’t end up recording my ride home, etc, etc. I bought the pro version because it’s worth it and soooo reasonable compared to the other expensive pro versions of other trail apps. This is THE BEST mapping app for keeping track of your outdoor activities!


As of October 30 2017 still no heart rate info. When I go to activity on iPhone the app states heart rate info was not captured. When I check the Trails app on my watch and go to stats heart rate is activated. Still no response from developer either. If this is a pro feature then they should state up front. I can’t seem to find this info in their advertisement on the App Store. I’m using iPhone 7plus and on Apple Watch Series 2.

I really want to like this app. I can't however because it does not work as advertised. Many glitches such as creating new trail despite same trail already recorded. Also, and this is huge for me, I have an Apple Watch and when I do a trail run or walk, the app never ever sends workouts to the health app despite that I have all activity from Trails activated in the health app.
