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.

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.

Old Maps-not good for hikers

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

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.

Nearly perfect

I've used this app for a number of years. The map quads are real usgs maps and best of all is the stitching that adjoins the quads into a multi quad view. I'm a rock hound and geologist and spend a lot of time in Nevada . You can see yourself while driving along the dirt roads and this feature is priceless for finding overgrown roads that would otherwise blend into the surroundings.
The only drawback I've found is the lack of private property delineation.
