Reviews for US Topo Maps

I use this more than OpenCPN for navigation as it allows me to save and use offline charts more intuitively (late 2025). Once Dave gets OpenCPN to function better maybe that will climb back up but for now this (pro version) is just the bar that needs to be beat. 4.7+/5 ☆

Perfect, manual style map! Does everything you need without taking over your route for you.

This app represents the pinnacle of bureaucratic catch-22 nightmares. I am trying to determine the height of the crater walls of Kilauea summit caldera, at top and bottom of each wall, with the height changing along each wall every three feet. Data more recent than 2018 is restricted by the FBI or CIA or both. Yet the terrain changes daily. Want more recent data? "Use the app." App refuses to use current data. Complain about the app? "That's from LIDAR data." Then why isn't it in the ap

I bought this app many years ago and suddenly they want me to buy it again. I emailed asking them for clarification. never heard back. buyer beware. I enjoyed the app, except you couldn't create a track without keeping the app open in front of you. if my phone locked, the track would stop recording.

I paid for Pro but doesn't load on my phone. Great tools and options love topo maps except Pro features didn't appear on any devices and not user friendly. Upon further research I found I only paid $30 for an ad blocker. The only thing different is the Shapes category and zero tutorial of how to use it.

I've been a happy user of US Topo Maps since 2016 and have just upgraded to the latest version. It has everything that I use/need/want at an incredible price. Some of my favorite features are the GPX imports, easy route creation, lots of information about routes (for example elevation profiles) not to mention the ability to add maps such as Geo PDFs and Geotiffs. The developers are accesible and responsive. I couldn't be happier! Thanks Atlogis!

One big problem This is an excellent app for displaying a wide variety of different maps. One serious negative is that it won't let me zoom in enough to read the labels. I can momentarily pinch zoom in, but as soon as I let go it snaps back out so i can't read it again. Why? Seems like an arbitrary restriction that greatly reduces the usefulness of the program.

Amazing app for years! For those who want a stable offline or online map client for running, hiking, walk etc that can record tracks, this is perfect! For more advanced users, you can export the tracks (automatic or manual). I use Syncthing to automatically copy the tracks over to my laptop and server so I can do cool things like open up my recordings on QGIS. I'm thinking I should now contribute to OpenStreetMaps by uploading my trail recordings. Highly recommend purchasing.

I had the premium version of this several years ago. I have recently installed it again to find out that I no longer have that. If there is a reason behind that or maybe got lost within the several years of updates that were missed. Then that is my own fault. I'd rate it higher if it didn't want me to pay for the premium service again. Other than that it is a very useful application especially for military or any other kind of land navigation scenarios that you may use it for.

I purchased the full version and have been using this app for a few years now and am overall happy with its features. It is simple. It loads and operates quickly. I can save tracks. I can import gpx files from friends. It is mainly used in offline mode using previously downloaded ESRI aerial or topo maps which I find the most useful. Downsides, you Aren't allowed to download Bing or Google maps to your device but can use them when in cell range. It lacks historical satellite imagery.

the program works but the map images arent sharp and are hard to see on a phone screen. it has a lot of potential to be a close rival to OnX but as it is, it can only tell you where you are currently in relation to surrounding landmarks that are shown on the map. as a route planning tool it is worthless until the zoom graphics get enhanced. if one has patience and a general understanding of the area they are in, it may help to become un-lost, or less confused as to which direction to go..

Unbelievable map resource...and im only using the free app. Will definetly buy the pro version when i get a new phone. In free you get crazy maps, overlays, weather, etc plus route tracking, so many GPS functions as well. If you spend time in the woods and want more than google/apple maps for camping, hunting/fishing, trail work, hiking etc, then you need this.

Whoever's rating this app at 4 or 5 stars has never been off the paved road or been out of cell service. Even if you get a map cached, its difficult to use, you can't zoom past a certain point, can't use the normal tools and is super slow. I sent my an inquiry for assistance but never heard back from the publisher. I would like my money back.

I'm still really new to navigating the wilds, but this app is easy to understand with the experience I do have. I was able to navigate a brand new trail I found using this. Definitely worthwhile to have. Still, its more of just a map than anything, I couldn't remember what direction I was going in so I had to turn back at a certain point. Wouldn't hurt to carry a real compass with you when using this.

Overall, not bad. But, if you want to download a detailed area of your state for when you have no cell signal - good luck! I've been trying to download a segment of my state for five days! First, there is no "resume" if the download stops. There is "restart" and the app tries to download everything again. It validates some tiles - but, the validation takes so long that my phone will pause so to inactivity before it finishes validating! I can never get more than 75% of level 16.

This is a fantastically useful app. It's generally easy to use, reliable, and provides a wide selection of base layers and overlays. Route tracking is accurate, and even while active, isn't too bad a drain on battery life. I still carry a backup paper map in more remote areas, but I'm very comfortable using this app as a primary. Really I'd like to give this app 4.5, not 4 stars, the half-star for the confusing process of importing data from external sources. That said, it's worth every penny.

I'm upgrading this to 5 stars. I finally found an Android setting under the app's battery usage that needs to be set to Unlimited. With that change, the tracking function works as it should. [Original post: Would be 5 stars if I could get the tracking function to work without having to keep the display on at all times. Turning off the display stops recording the track, which makes it unusable for anything longer than a very short walk. I've given the app every permission I can find and turned off the device's battery-saving features, but have not been able to find any way to solve this issue.]

I recently used this app as a fall back for a land navigation exercise I was running. There were a lot of pros and cons I witnessed in two days of heavy use, but the experience was positive over all. The map was more accurate that I expected, and the GPS was accurate when it was working. My problems with the app are GPS reliability and way points dissappearing for no reason (fixed by going to legend, clicking on the way point, and pushing "show on map"). Needs some work, but a very useful tool.

Fantastic app! The only complaint is that I wish there was a way to overlay multiple maps at once. I would love the ability to set the base map as satellite imagery, then overlay both aspect and contour maps! Unfortunately, it seems only one other map can be overlaid at a time. Other than that, love it!

This app puts an entire map cabinet in your pocket! Gone are the days of an entire back seat filled with maps and still missing the needed one. It's also a lot easier to determine your map location using the GPS, than by searching for identifying land features. Unfortunately, the concentration on routes often interferes with simply displaying the map and my location. I have not yet wanted to save a route, but an easy way to save a point would be nice.
