No price levels displayed on your account when you want to check on renewal. This creates a lot of frustration when you just simply want to check the current pricing level before you make a decision on membership levels.

Great navigation app. I use it mostly for hiking, some for biking, and I have even used it sailing and paddle boarding to make fun designs, like a heart or a flower. My only complaint is that it tends to register long with the distances. That's the only reason for giving it 4 rather than 5 stars.

I just got back from a fun hiking and camping trip. I downloaded the offline maps because I knew I wouldn't have cell coverage. The HUGE problem I had was that when I needed the maps in areas without cell service the app wouldn't even launch. It would get stuck on the blue loading screen. Thank God I had a backup paper map and compass (and know how to use them). Why did I pay so much for an app that's false claims could have gotten me ☠️?

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 have been using on x since fat map was bought out. It wasn't my favorite then, but now the app is becoming more useless and hard to handle. Its offline maps have dropped in their quality/usability, with issues finding north, and the 3D function for me. The 3D maps in general feel janky and awkward, making it more difficult to correctly plot my planned route and get an accurate feel for the topography. If I have to just use the topo version, I may as well use a different app.

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.

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 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.

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.

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.

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.)
