Offline USGS topo maps with built-in trails, trail recording, elevation profiles, and GPX import and export. No account, no subscription.
Download USGS topographic maps of the United States and use them offline, with no account and no subscription.
Topo Maps US is built for people who go where cell service doesn't: hikers, backpackers, hunters, anglers, paddlers, mountain bikers, geocachers, and anyone who wants a real topographic map in their pocket.
MAPS
Choose from three USGS map layers: standard topographic, aerial imagery with a topographic overlay, or plain aerial imagery.
OFFLINE
Tap the map squares you want and download them before you leave. Downloaded maps work with no Internet connection and use no cell data in the field.
TRAILS AND POINTS OF INTEREST BUILT IN
Every map download includes the trails, summits, lakes, campsites, and other named places in that area from OpenStreetMap, so you can search them by name while you're offline.
TRAIL RECORDING
Record where you go. Recorded trails show your path on the map with distance, elapsed time, and average speed. Recording stops automatically when you start driving, and any drive at the start or end of a trail is trimmed off.
ELEVATION PROFILES
Every recorded or imported trail gets an elevation profile with distance labels and color-coded grade shading. Drag along the chart to see the matching point on the map, its elevation, and the time you passed it.
FLAGS
Mark your current location or any spot on the map. Flags record coordinates and elevation, and you can add notes and organize them by color: geocaches, trailheads, summits, camps, and so on.
NAVIGATION
Pick a flag and follow the direction arrow, driven by your compass heading, with the distance remaining. Handy for geocaching and for finding your way back to camp or the car.
LOCATION
See where you are on the map, your elevation, speed, and the accuracy of the GPS fix.
MEASURE
Trace a route on the map to measure its distance, then save it as a trail to follow later.
IMPORT AND SHARE
Import trails and waypoints from GPX files and geocache LOC files. Share your flags and trails by email, Messages, or AirDrop as standard GPX files that work with any GPS unit or mapping software. Back up your maps and data to a computer over Wi-Fi.
Designed for iPhone and iPad.
Note: Continued use of GPS in the background can noticeably reduce battery life.
So far i am liking this app really well. It took me a bit to figure out some things - like down loading the map squares. But it seems to work well for looking at the map and seeing where you are. One item about this app that i think is killer is the distance drawing facility. One selects the measure option and then draw lines on the map then you see how long that route is. It doesn’t appear to do some other things one might expect, like track you route, but what it does it does well and i prefer that!There seems to be a few bugs: My most compelling issue is that somethings just don’t show up. EI: I wanted to look at Long Island, Willapa Bay Area, but it wasn’t showing up until I changed the zoom level. So I had to down load the squares, then zoom in quite a bit to se the island.One thing that could be improved is the transfer/loading of the tiles. As far as I can tell, one has to do this one tile at a time. Select a group of tiles and download. I commonly forget to download an area, then am in the mountains and off the grid before I remember I don’t have the map.So I spend my evenings selecting 20 or so tiles, downloading them to my phone. I also have a tablet, that I wish just could have the same tiles I downloaded on my phone. And, when you get a new phone, one has to start the processes all over again….
Excellent app!

This is a really excellent topo app without the silly cloud or social features that seem to be commonplace on nearly all other topo map apps. Thanks developer! I owe you many beers for all the trouble this app has gotten me out of in the mountains. Some of what makes this app great:- Doesn’t require a user account to access the publicly available topo and imagery base maps. Just download before you go, then turn off Map Management to hide the download maps interface. - Allows you to save the maps for offline use which is the cure function all such map apps should have but in reality many others do not. Let’s be realistic, when you’re in the mountains you won’t have cell service and this developer gets it. - Can trace your route, drop flags, and categorize and hide them to reduce map clutter. - Can get your GPS location instantly (new awesome feature, and useful for emergencies)!- Uses little battery when tracing and less when not tracing. I was seeing ~10-15% for a half day of hiking on an iPhone 8. (If you are seeing high battery drain, it’s not this app. It’s probably your other background apps refreshing. Turn off background app refresh for useless apps, or toggle low battery mode to disable it globally and you’ll see that this app uses minimal battery. Also, use airplane mode If you’re not in a service area.)- Map export is reasonably easy: send via email, or bulk export via a simple freeware, no-install WebDAV program.
Direct USGS Topo Map Access
KRRK
If you want real topo maps beyond “terrain”, this app is the one you want; it’s built to be useful, not to make money for the author, and it shows in every feature. You get direct access to real and downloadable USGS topographical maps, with or without satellite imagery. It does lack some nice features other apps have, but I always find myself using this one instead because it works and provides direct access to the thing I actually want, the map. It’s simple, clear, and direct because it was written in the true spirit of the Internet, open information for all. The author made a very helpful tool and I thank them for it. Features: multiple map choices, map downloads for offline use, track recording, waypoint recording, on-the-fly measurement tools, and full data exporting including downloaded maps, all from a small, simple, cleanly coded, efficient, old school, useful app. Yay.
Great topomap with the right features

This is a great app! I have been using it for about 5 years give or take a bit. You can download the maps, estimate routes and never worry about being on line. There are a few features that others offer, but every app has something you want that doesn’t exist. The beauty of this app is has the most important features and has a one time fee. You can store your maps on your computer to make changing phones easier. Although this feature requires a bit of technical know-how, it seems to work seamlessly- at least on my Mac. The one feature that would make this easier is to have a laptop map manager(?)! Get updates and the disperse them the you have a bit of time to update.The short story is if you want a good mapping app, that works, this one is it. I use other apps, but I always come back to this app to do the real work.
• Recording stops when you start driving. Finish a hike or ride and drive off, and the app notices, sends a notification with Stop and Keep Recording options, and trims the drive from the saved trail. Turn it off in Settings if you prefer.
• Trim drives from older trails. Open a trail that ends with a drive home and the app offers to remove it.
• Cut a trail anywhere. Scrub along the elevation profile and tap the scissors to drop everything before or after that point.
• Save polyline measurements as trails, not just freeform ones.
• Elevation profiles for imported routes and saved measurements now follow the terrain between widely spaced points instead of drawing a straight line.
• Fixes for flags that never got an elevation, plus memory and stability improvements.
