This app may be good for highly used trails, but finding places to backpack around my area sucks. Most of the trails have little information and no hiker feedback at all. Trying to find trails by map view is almost impossible because the trails don't stand out well at all no matter the basemap layer. You can't see anything if your zoomed out very far at all. The search feature is useless too, won't find trails I know exist. A nice interface is not enough.

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.)

Strange "trails" at time. Marked a single pedestrian crossing as a trail. Nothing else in the entire area. Marked an elite country club golf cart road as a trail as well as private property roads in two rich folks properties. Not sure how trails are vetted. I asked a few years ago before subscribing and was told trails are vetted. Unsure about that now. Nice that you see property ownership like in the hunting app. Seems focused on popular/hip outdoor states, think CO & UT.

Basic membership doesn't provide any good functionality anymore it's all part of the Premium plan. Might as well just use Google maps...I don't use it enough to upgrade. Once Basic pulled the slope angles layer I stopped using it. Everything you try to click has a lock and you're constantly prodded to upgrade to premium. The user interface is also clumsy and hard to navigate at times. Offline map quality sucks. The app is glitchy offline too which is frustrating. Not impressed.

Maps are great for looking at, especially cool in 3D. Unfortunately, the tracker seems to crash (or auto-stop) too frequently to be useful (will stick with Hiking Project for that). Would like to see a good trail searching tool to boost usefulness.

I recently switched from another app and am paying for the premium version. My main complaint is no elevation graph offline, that's so helpful it's probably a deal breaker for me. I'd also like to see 3D available for my offline downloaded maps. I've tried the app on the trail a few times, I like the detail in the satellite image layer and the location looks to be accurate. Still figuring out whether I'll stick with it or try another.

I primarily used it for trip planning, and for that it's fantastic. It has a great interface to plan a route, and the route snaps to the trail very well. it's annoying the app defaults to find nearby trails, but it's easy enough to go to tools. My problem is with the maps that it uses. Many campsites aren't listed, and one that is indicated on the map was removed 20 years ago (some trails too)! I mostly hike in New Hampshire, so other regions might be better. I'll stick to Caltopo/FarOut

This app is a total no go. Extremely glitchy. the app crashes constantly, the features bring up error messages, and there are tons of local trails that aren't available. I bought the premium version because I wanted a good app. I hike around 1000 miles a year in the Colorado Mountains. I completely don't feel like this is a dependable or even safe app to use to go into remote areas. In the end the app just sucks and that's a fact. Don't get the free version, don't buy the premium.

Unfortunately not as reliable as OnX hunt. Even when maps are downloaded at high resolution, the offline map is extremely slow to load and grainy. The app has also reverted to basic subscription status when I'm offline, leaving me without access to the "elite" tools I paid for. Extremely disappointing, and possiby dangerous to rely on when recreating in backcountry environments.

Great map but doesnt include portages or camp spots. please On X im a premium user but use this map mainly as backcountry canoe and hiking for days or weeks at a time. would love if you could include the portages and camp spots on map. love everything about this Map app except those things. would love to just have a one stop shop for route planning. we're up in Northern Ontario. having to use avenza alongside, on x is kind of a pain.

I am only giving 4 stars because I got an email saying that my account is renewing next month, but there is no amount. Nor is there any info on the amount in the app. For an app this popular, it doesn't make sense that it doesn't give you an amount that your subscription will be renewed for. Other than that, I love the app. Update: Didn't know I would, but I got an email from customer service telling me what the amount would be. P.S. It should tell you in the app.
