This app has great features. I had really high hours for it. I used it on several hikes and each one had missing information. Part of the trail was closed or changed, a whole trail was permanently closed. I don't know how they get the trail information. Maybe they need more hikers giving them information. For that price point I need much greater accuracy.

Thanks for the thoughtful feedback and for giving onX Backcountry a try. Trail status can change quickly and we’re sorry some info was out of date—that’s not the experience we want. We use multiple data sources plus user reports, and your input helps. If you have any questions, please reach out to our support team with [email protected].

The app is easy to use and works well for the most part. I can only give 2 stars though, because it is missing parts of the Superior Hiking Trail, so I am unable to create a route for a section hike. With these missing sections, the app is unusable for my purposes. I requested a refund for the premium subscription through Google and it was denied - what a waste of money!

Requires a subscription now to view trail info. Used to be able to tap on a trail and see the trail info, but now it all requires a subscription. The features that come with a subscription aren't bad, but sometimes I can't afford it and would just like to look into general trail info, especially when I want to compare things across different apps. I probably won't be using this app again for at least a while because of this. (And I don't buy them doing it just so you can save all your trails.)
