The app is not very useful but the thing that pisses me off the most is I can't figure out how to cancel my membership. The directions to cancel give you options that don't exist in the app. It tells you to go "my accounts and orders > membership questions" but the only option in my app is "my account" and there is no "membership options" on that page

I am a long-time user of GaiaGps and sometime user of AllTrails. I was hoping to find a new application to address some of the map issues I have with GaiaGps. I liked that the map did not appear to be Open Street Map based and I liked the elevation rate coloring and the general look of the map. But I stopped using it because the onX Backcountry maps are missing too many trails and have errors. When I first bought the subscription, I sent feedback on some missing trails (Google Maps, Gaia, AllTrails OSM all have them) and obvious errors (one trail where one does not exist, a road going through a lake, a road in the ocean). None of these were fixed in the almost a year since I reported them. Having an accurate representation of the actual trails is the most important feature for me. I don’t feel there is sufficient effort in maintaining the map to justify continuing the subscription especially when Gaia and AllTrails have more accurate maps. I really wanted to like this a but I cannot recommend it.

Hello there! Thanks so much for the review. We're very sorry if there are still some unresolved errors on the Map. I'd highly recommend reaching out to our support team at 406-540-1600 so that we can take a deeper look into them and bump their priority in the resolution queue. We'll get these fixed up for you!

No offense to this app but All Trails is much better. I never needed to pay to discover new local hiking trails on All Trails. I eventually bought a subscription from them because I love the app so much and it is quite useful while hiking new trails. You should ditch the free trial and let people experience your app for a little while longer. If it's good enough then they'll pay for it.
