User Reviews
I downloaded and set up a one year elite for $80. When I logged into the app it showed me an offer for $40. When I clicked on it, it said I was already subscribed. So why didn’t I get the offer when signing up?
The app constantly nagged me for a review even after I stupidly paid for a subscription just to get access to public information that you can get for free at sites like OpenTrailMap.us, so here’s my review: don’t pay for this. These clowns bought the REI Hiking Project, MTB Project, Powder Project, Trail Run Project, and Mountain Project, then OnX acquired them and ruined them all with their subscription plans that they gate everything behind. Everyone who contributed anything to these just gave free value to capitalist pigs. Don’t support this and use something open source instead.
Signed up for their year promo deal only to find out they scam you to pay more money for the options you believe your getting in the advertising, but aren’t there!
I’ve used OnX Backcountry for several years now. I find it fits my needs better than other mapping/route-finding apps. The layout is intuitive and quickly accessible. With offline maps, I don’t need to worry about cell service. The features are too many to list here, but OnX frequently offers free seminars/tutorials/classes that teach basic and advanced features of software. Their customer service is also top notch. Of course, no matter what tech you use always have a map and compass with you and know how to read and use them. I’ve been backpacking for 40 years and I gotta say, OnX is the mapping app I’ll stick with.
The OnX world continues to grow at a rate only outpaced by their greedy fees. There are many OnX specialty apps these days, and every single one of them has its own fee and usually limited to 1 state. You would think it would be 1 app with all those features. Afterall, if you’re hunting or fishing, you’re driving and hiking in. But no. You have to subscribe to all of these apps all separately or you have to get the elite subscription. However none of these apps are integrated and so they are all essentially standalone. They all require their own updates and favorites and learning curves and features etc etc etc and subscriptions. Lame and cheap cheap cheap cheap cheap. There are much better alternatives on the market that aren’t so expensive and that offer combined features. OnX is garbage
great
Kept me safe
This app was so much easier to use when there was a dedicated weather button on the Home Screen
Super easy to use and quite accurate
Works
I love that you can make your own route and I will know if my legs can make it before I even attempt it.
Cool app
