Coverage: this app makes available more than 70,000 maps covering the United States, including Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands, and Canada.

The Maps: This app uses high-quality scans of the traditional USGS and NRCan topographic maps which have been the definitive resource for hikers and other backcountry users for many years. You can make the terrain stand out with hill shading, using simulated sunlight from the direction of your choice. This app does not use the new "US Topo" maps because they do not show hiking trails and lack other details: please see the web site for more details.

Downloading: US maps are around 8 MB in size and download in a few seconds on a typical home broadband connection. Canadian maps are larger. Both cellular data and WiFi can be used, though WiFi is likely to be more reliable in most cases.

Topo Maps Reviews

recent purchaser

poor quality maps  recent purchaser  2 star

I would save your money. Maps are just scans of usgs topo maps. Scan quality is poor (low resolution), the ones i tested all appeared to be crooked. I uninstalled the app and asked for a refund by never heard back from the vendor.

Booger finger

Awesome  Booger finger  5 star

This is the best app in the store. I do a ton of camping and use this app constantly to find fire roads and trails. I highly recommend this to any camping or backpacking enthusiast. It would be nice to be able to download multiple maps at once instead of one at a time.


Worthless. Want a refund  Luckydragon13  1 star

Maps are outdated and worthless. Put in location and map puts me miles away. No tracking features. Worst $8 I have ever been scammed out of. Doesn't look like there is any refund options.


One Problem  Erflowers  2 star

Topo maps are so out of date it's really bad. I checked the maps of my area and in 1958 there was no "my area". According to the map I'm out in the wilderness. I'm afraid accuracy is a big problem. The maps are nice to look at but the airport here was moved in 1976 and these maps have it in its old location. About 4 miles in the wrong direction. Too bad I really wanted to like this app.


No updates, disappointing  drabenau  2 star

If I had known this app would not get regular updates I would never have bought it. Both the older maps and lack of tracking is way behind the curve. Look elsewhere.


5Stars, same type maps I carried in army  Kutzukid  5 star

Same type maps I carried in the army. True topo maps.

J Lima

Great functionality, very well done  J Lima  5 star

This is a fantastic app for topo maps. I've used this app for a couple of years and love it. With all usgs topos, as well as canadian maps, this is the only topo maps app you need for the us and canada.


This is the topo app for backcountry  Alaric45  5 star

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.


Superb App  Tesla_2016  5 star

This app is very simple to use and yet very useful for what we really need in the field. The fact that you can select an entire region (multiple quadrants) for download is worth its weight in gold. In addition, once a region is downloaded, you can load a composite of them with the arrows as you start scanning beyond the loaded quadrant. These are the features I really look for and use most frequently.

Far out man

My favorite app all time  Far out man  5 star

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.

Old Maps-not good for hikers  Finestudio  1 star

I purchased the app as a backpacker- hiker companion thinking it would replace the defunct Accuterra app. This app downloads maps very quickly but they are very old, lack solid trail detail and are hard to use. If you are backcountry hiker or camper - don't waste your money. There is no trail hike trek recording of where you have been, The search feature is confusing and at times does not work. The location button often prevents moving around a map area to explore an area due to wanting to " locate" you. The fix is to repetitively turn off location services- but what a pain. Overall, very disappointed with general operation as well as map quality, will be dumping app.


Hunting, hiking, camping, fishing  Cutieface77  5 star

Very reliable, even with limited or no connection. Just be sure to download the maps before heading out. The locator function works well even with almost no signal! I've been using this app for a year with absolutely zero complaints. Love switching between this and Google Maps to compare Topo with birds eye view, but rely mostly on Topo once I get out into the forest and hills. Works great for planning hunting trips: I spent weeks studying geography to predict deer movement, then put that knowledge to work when setting up stands, and it all worked out exactly as planned. Buying custom topo maps would cost more than this app, and take up more space. As long as your battery lasts, even if in airplane mode to save it longer, this app will serve as your map.


Keeps me from wandering  MOhiker  5 star

Whether I'm hiking in the Ozarks or in the deserts and canyons in Utah, I rely on this App to keep me on the trail. I understand that USGS Topos vary in their update ages, but I depend on the coordinates and contours more than anything else, and those don't change much if at all.


No Topo, really old style map  Sonksonk  1 star

I bought this because it is suppose to be TOPO but it is really bad, not like any Topo I own. Just use google, it's free. If you use TOPO, why would I want to enter an address, no you enter your God cords duh! Horrible app want my money back

Terra Cruiser

Great App!!!  Terra Cruiser  4 star

Bought this to use while offroading and after first use I'm thoroughly impressed. Would only add route tracking to increase to 5 stars. Great res on topos, easy to download maps! For those upset about old maps, they are USGS TOPO maps and many are old. Good maps, even if they are old.


Some missing roads  JSilva35  3 star

I've found some dirt roads missing. One is the very road I live on in Idaho. It should be there unless this is a very old map. Seems like a pretty good app but I don't totally trust it & advise to use with caution.

Ak person 123

No western Aleutians  Ak person 123  2 star

Please add the western Aleutians or don't claim to Cover all of Alaska. I purchased this app for adak and now it's useless to me.


Awesome app for hunting  Kysandman  5 star

I've used this for years and it's easily the best topo app I've seen. It's great for scouting new property and going deep on public land to get away from everyone else.


Well done, very handy.  Clockwork.  5 star

No complaints. Simple and useful. Thanks.
