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. - Do please visit for complete instructions, so that you don't miss any features.

App Reviews

  • Just what I wanted

    By 
    I was considering buying a 250-300$ GPS. I figured I'd throw down a couple of bucks before I dropped that much cash on another device, to try this app out. It is exactly what I need! I have been backpacking / hiking for over 30 years and I am so happy with this app. I am still getting used to how awesome it is being able to tell exactly where I am during hikes or driving on logging roads. This app is amazing. There is no cost to download topo map after map, just pick which ones you want! Took me a bit to figure everything out but now that I have the best part is that I don't need another device, charging cord or any other crap, which is what I was dreading more than the price tag of a gps device. Everything is neatly available on my phone. I haven't had any connection issues weather there is cell reception or not. It just tells me exactly where I am.
  • I use it on every hike

    By Jasonc_
    So much easier than carrying a sheaf of paper USGS quads! I use this app on nearly every one of our hikes, and love the fact that I can pre-download map data for use in the back country where I often have no cellular service. And I love being able to merge adjacent topos. Somehow I'm always hiking on an edge or at a corner. I just wish for some way to sync the pins/placemarks across multiple devices
  • poor quality maps

    By recent purchaser
    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.
  • Awesome

    By Booger finger
    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

    By Luckydragon13
    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

    By Erflowers
    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

    By drabenau
    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

    By Kutzukid
    Same type maps I carried in the army. True topo maps.
  • Great functionality, very well done

    By J Lima
    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

    By Alaric45
    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.
