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.

This update is for compatibility with the iPhone 6s, along with various minor bug fixes. If you don't have an iPhone 6s there is not much to be gained by updating.

  • 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    Topo maps are so out of date it's really bad.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.
  • Superb App

    By Tesla_2016
    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.
  • My favorite app all time

    By Far out man
    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.
  • Very disappointed

    By ksquire
    While this has some nice features, I was very disappointed to learn that it does not support tracking. And the very first screenshot of the app in the appstore shows a map with a TRACK on it!!!! That's very misleading and I want a refund!!!!! From what i can tell, this app has been out for a long time, and the manual says "tracking features are coming soon..." Where are they? The developer hasn't provided an update in almost a year. Even free map apps provide tracking!!
  • Great but..

    By Yarrr123467854
    It would be good to get more features such as "bread crumbs", importing routes and the like. I also had an issue with downloading maps after getting an error due to spotty cell coverage. That did not allow me to download maps even when I had good coverage or wifi afterwords. Still does not work after deleting and reinstalling app :(.
  • Not a topogrophy map

    By Rydnu
    Need a refund!!
  • Excellent App

    By Recalledtolife
    This is a wonderful app. Allows to download USGS maps for offline use.
  • Not intuitive at all

    By ineedareed
    I just bought this app and uploaded a gpx file into it. I can see that the file is in the app with all my waypoints and tracks. But for some reason I can't see the waypoints and tracks on the map. I see no button that indicates how to do so. Nothing. I hate this app and wish I hadn't wasted my money. Total garbage as far as I can tell. I did download GPS Tracks and it works beautifully.
