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. In the U.S., 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. We have many ideas for additional features to add to future versions of this app; if you have ideas or other questions or comments, contact details can be found on the website, The website also has more screenshots and other information.



  • Doesn’t support basic GPX Tracks

    By Captainahob
    I can’t believe I paid $10 for this app. It’s so poorly supported. Why bother with GPX support if you’re only going to support waypoints? Also I got lost once because the app must be closed and re-opened to update one’s GPS location on a map after locking my phone. Otherwise it will tell you that you’re in the same spot until you finally figure out that you’ve been moving while your GPS location hasn’t.
  • What a disappointment

    By Miss...Vee
    I seriously wish I could get a refund for this.. what a joke.
  • Great app! Very helpful!

    By mtessier23
    Used this app to find the drop in to a canyon in Zion. The maps were quick to download, even when I had bad service, which was great, because I didn't think to download this app until we were driving to the trailhead. It was easy to see where we were and compare it to where we were supposed to be. We made a couple of wrong turns and this app made it super easy to get back on track!
  • Great app

    By DesertRain102938
    I appreciate the older maps! Lots more info that has been removed off newer maps. Works great. Good job.
  • 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 i. This app has all usgs and canadian government topos. It doesn't provide tracking, profiles, etc, so if you want that look elsewhere, but this is an excellent app for navigation, pins, and topos.
  • Best Topo App!

    By will505
    I've had this app for over five years and it is the best. No subscription fees or in app purchases and it just works.
  • Excellent and Reliable

    By WineReader7
    The app is great, and really saved my butt in the Denali backcountry when I was having doubts about my map reading skills. It does great offline and the basic functionality is simple to use. Also useful is the waypoint feature--you are able to track your progress and timing on hikes and ensure you don't get too far out to make it back by sunset. The only thing that could be improved is adding a time stamp to the waypoints--I've been doing that manually.
  • 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.
