1. 5/5Nothing Better for Exploring

   I’ve been using these topo maps for years - pretty much everywhere I go I download the local area with these maps if I’m going to be out and about at all. Also, where I live I like to explore the back country, often overland with no trails or roads or on old two-track roads hours away from anywhere with cell service. These maps have been invaluable for offline use. I would say, however, that the most interesting use has been the fact that the old WGS84 took maps this app uses show a huge amount of things that modern maps omit. Old structures, mines, prospects, old roads, trails, and miscellaneous items that have been forgotten by all - including modern cartographers - are shown on these maps. A lot of these old things are still around, and are still visible even on satellite maps, but if you were only using modern (non-satellite) maps you would never know they were there many times. I love detail, and I hate how modern maps ignore so many different features that are in fact extant. These maps are perfect in ways so many other newer maps fail. A few things I wish it had though: 1. The ability to add kml files, including tracks and shapes etc. 2. A mode where the gps would still track but not force you to be centered on your position. The second tap just shows where you were when you tapped it the second time. 3. The ability to switch between a height map and the gps elevation. The app currently uses a hidden elevation map (the same thing it uses for the line of sight feature) to tell you your elevation, not the gps. There can often be pretty drastic differences between your actual elevation and the elevation it shows. I’ve seen these when I’m flying my plane a number of times. 4. All of the above without a subscription and add on features you have to pay for as well (like the new app).

2. 5/5Issue w/ Downloading Maps is Fixed!

   OCTOBER 2025: The issue with being unable to download new maps to my device has been fixed. when trying to download new maps, I would get an error message saying the map wasn’t available for download or something like that. I sent an email to the app developer last night, and six hours later he had responded and said the problem was fixed. And it really was! After all these years, this is still the best topographic map app out there for use in conjunction with hiking and exploring.

3. 5/5Best app for US topos

   I live with topographic maps in the field both for work and recreation and after many years, I still find this the best app for accessing topo maps out there. The interface is clean, downloading maps is quick and fairly straightforward, I can upload text files of waypoints, I can mosaic maps. This app does not chew up battery as some do. The only downside is tied directly to the maps themselves, which are dated as USGS has bailed on true updates, instead turning out substandard GIS-based maps that, while more up to date on roads, are otherwise lacking. So long as the user knows the limits of these maps, there is no problem.

4. 5/5My favorite app all time

   I have owned this app since its launch and can honestly say it is my favorite app period. I am an avid backpacker and hiker and this app has allowed me to find some of the most amazing places in the wild. Maps must be downloaded while you an internet connection, but the gps usually works while out of service so you can locate your position on the topo. I love the ability to link maps together and zoom way in for detail. The map quality is identical to paper topos. I used this app while hiking the John Muir trail and it was great for checking my location and finding off trail lakes and campsites. The search feature works really well so you can find the map you need quickly, download and head out for your adventure. Can't believe this app isn't more popular as it is awesome.

5. 5/5This is the topo app for backcountry

   I love this app. The map resolution and stitching are excellent. The maps are stored on your phone, so it works way out of data range. Each map is about the size of a standard photo, so you can download hundreds if you want. You see your position on the quad map, and you can drop waypoint pins at your current location or at other points without going there first. The only thing it doesn't do that my old Garmin does, is show your track. The compass link function lets you aim the whole map at a distant object to identify it. You can also switch the map to Google aerial photo of the same area, if you are in data range. I like the old '83 topo quad maps. You see old trails that aren't on newer maps. You wouldn't use this app for driving around town, because a lot of newer roads will be missing, but rarely a problem out in the woods. This app has almost completely replaced my old GPS. The tutorial is nice and clear.
