Map displays beautifully and zooms flawlessly " * Includes Canada (at 1:50,000), the contiguous US (at 1:24,000), Alaska (at 1:24,000 and 1:63,360), Hawaii, Puerto Rico and the U.S. Virgin Islands. * Locate the maps you need on the satellite view. To install a map, touch for about half a second. Touch again to view it. * Search by name for over a million towns, peaks, lakes, parks and other features. * No network connection is needed once the maps have been installed. * Mark waypoints, and import and export waypoint files in GPX, KML and CSV formats. * Touch the "current location" button to see where you are, and the compass button to align the map with the ground. * See coordinates in NAD27 or WGS84 degrees, degrees minutes and seconds, UTM, or MGRS formats. * Measure distances (miles, feet and km) and bearings (true and magnetic). 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 https://topomapsapp.com/ 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, https://topomapsapp.com/. The website also has more screenshots and other information.}

OCTOBER 2025: The issue with being unable to download new maps to my device has been fixed. when trying to download new maps, I would get an error message saying the map wasn’t available for download or something like that. I sent an email to the app developer last night, and six hours later he had responded and said the problem was fixed. And it really was! After all these years, this is still the best topographic map app out there for use in conjunction with hiking and exploring.

I'm a land surveyor and this app comes in extremely useful. The quads are pretty well registered and the contours are quite accurate. The biggest downside is that many of the usgs quads are not current.

Been using this for years. I love it. I recommend it to everyone. The downloadable maps are so small I can have multiple states available offline on my phone. The gps function works without cellphone service so you can always find where you are. And the waypoints I’ve created over the years are all saved in gpx files so they’re easily transferable when you update your phone. If eight bucks sounds expensive: imagine the cost of buying your entire states topo map collection, then realize you have the entire US/Virgin Islands available to you.

Pulled up the map of the third largest city in MN. The map is decades old. Shows old names of buildings and structures that are not even there anymore. Also fails to show newer buildings and locations

I’ve been using this app since 2016 and have thoroughly enjoyed it. I love having access to all the Topos wherever I am. I use them backpacking a TON, on trail and frequently off trail. I also use them while rockhounding in obscure out of the way places up canyons and washes. I use them to look at topography to find flat places to camp and to plan routes. It’s easy to use. You can save routes, put in labels and color code different places. I like that you can use a high resolution or low resolution setting. It allows me to have all the maps I need without all the space taken up. Even the low res maps are good. Also being able to measure line of sight from one point to anyplace else is great. The one time I was having problems with my phone and I reached out to the developer for advice he wrote me back super fast with the perfect solution. Don’t hesitate to buy this app. It’s so worth it! I’ve gotten my money’s worth many times over.

Maps offered for Canada are over 10 years old. Lots of roads missing.

I’ve tried them all (Gaia, OnX, Earthmate, and others) and by far this is the most reliable and intuitive topo application of them all IMO. It has some fantastic features the others do not, and it’s the closest you’ll get to physical topo maps in hand. Sure it doesn’t have all kinds of layers to overlay, but do you want to be caught up in techno-glitter or navigate? Earthmate is lousy, OnX the worst, and Gaia is not bad. Topo Maps+ is pretty good also. This app, however, is always my go to. Kudos to the developer for focusing on simplicity and functionality rather than bling subscriptions that simply bilk you for a lot of crap you don’t need.

This app is fantastic. This is my go to for any backcountry trip- put my phone in airplane mode, use gps on the maps, and the battery will last for days and days. This has made the navigation on so many trips so much easier-from month long mountaineering expeditions to packrafting in remote places to backcountry skiing day trips. Also, the support offered is fantastic. I recently had a problem and got a really fast response from the app creator.
