View USGS 1:24,000 topographical maps on your iPhone or iPod touch. Ideal for hiking and other backcountry activities. Map downloads are FREE Provides more than 69,000 maps covering the United States and ...
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                     Best Topo App will505
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                     Excellent and Reliable WineReader7
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                     Just what I wanted 
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                     I use it on every hike Jasonc_
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         poor quality maps recent purchaser
This is the best app in the store I do a ton of camping and use this app constantly to find fire roads and trails I highly recommend this to any camping or backpacking enthusiast It would be nice to be able to download multiple maps at once instead of one at a time                     Awesome Booger finger
Maps are outdated and worthless Put in location and map puts me miles away No tracking features Worst 8 I have ever been scammed out of Doesn t look like there is any refund options     Worthless Want a refund Luckydragon13
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         One Problem Erflowers
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         No updates disappointing drabenau
Same type maps I carried in the army True topo maps                     5Stars same type maps I carried in army Kutzukid
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                     This is the topo app for backcountry Alaric45
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                     Superb App Tesla_2016
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                     My favorite app all time Far out man
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         Very disappointed ksquire
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                 Great but NDemitri
Need a refund     Not a topogrophy map Rydnu
This is a wonderful app Allows to download USGS maps for offline use                     Excellent App Recalledtolife
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     Not intuitive at all ineedareed
I live with topographic maps in the field both for work and recreation and after many years I still find this the best app for accessing topo maps out there The interface is clean downloading maps is quick and fairly straightforward I can upload text files of waypoints I can mosaic maps This app does not chew up battery as some do The only downside is tied directly to the maps themselves which are dated as USGS has bailed on true updates instead turning out substandard GIS based maps that while more up to date on roads are otherwise lacking So long as the user knows the limits of these maps there is no problem                     Best app for US topos Cjones-CU
Good interface was confused by other apps but not this one Download multiple maps at once by dragging over a region Have used on trails works very well Thanks developers                     very usable ilya239
This is the best way to get topo maps on your phone in a seamless way It really works great and I have never had issue with it                     Priceless CognitiveG
I have had this app 4 5the years now and use it all the time while on the Jeep trails and hiking This is by far the best GPS             Topo Rvtecnorod
Definietely worth the 8 An amazingly helpful app Some complain that the maps themselves are older I think it s a good thing Shows features that are no longer shown on modern maps I m very glad I purchased                     Great app GrahamSpencer
Just great it works in offline you can set waypoints it shows where there are mines just amazing                     Most useful app Spamcable
Excellent app                     Just another user ClarkVTECH
This app I amazing Works without service It s never been wrong You should make an Apple Watch version to go with this too for quick compass work triangulation and for just a quick look at how far youve gone and have left to go                     Best app for backpacking Land Nav and Survival Sam1728384
Totally worth the money                     Love it The most random person 321
This is honestly one of my favorite apps and rightly earns a place on my home screen It s truly indispensable I cycled over 1 000 miles around Washington state and 1 500 miles down the Pacific coast back in 2009 and the app helped guide me every step of the way With my solar charger there s almost nothing I can t do with this app and features are constantly being updated as well Definitely worth the money                     An indispensable app jr98664
Best app for adventures Great customer service Thank you                     Invaluable CometWaves
I love this app I use this for all my hiking hunting and driving in the mountains The maps are great detail and have never led me astray                     Best Map App for Outdoors Electri6man
Used this puppy a ton over the past two years to map hiking routes and to discover great hunting spots App works flawlessly Thanks                     Hunting and Hiking ReconRiley
So far well worth the money Great maps and easy to use I ve been looking for software to use like this for awhile now and I m glad I found this A                     Awesome Nardojoel
I greatly enjoy using this app I can download map sections for offline use I love that with a tap of a button the map points in the direction I m facing I m sure there could be some UI improvements but I m not sure how I d do it better I do wish there were a greater variety of icons to use as pinned locations but that s no big deal                     Great SteelMinistry
This has been my go to app for years for hiking and backpacking There is a known issue for 6s users as documented on the author s web site The problem is touching on a grid square to prompt for downloading a map does not work with 3D touch If you encounter this issue goto Settings General Accessibility 3D Touch and toggle to Off Now the app behaves as before and you can download new topo maps by touching the grid When finished toggle 3D touch back on Happy hiking                     Workaround for 6s users Hey_aj
Recently updated to an iPhone 6s and topo maps no longer works I deleted the app hoping that re downloading would restore its glory but unfortunately it didn t work and deleted my waypoints and saved topo maps What used to be a great navigational all for the back country doesn t seem to work with the new iOS Bummed     Used to work great hooookup
Was a great app Down loaded it four years ago I just got a new iPhone 6S and now I can t download a single map onto the phone HELP     JimJaw Buy a map to
I can t highlight boxes I have 0 option that shows i should have All it allows is to take me to other maps on my phone I ve waisted 7 99     iPhone 6 issue Dprestonc072085
This is a great app I use it for backpacking Have on both an iPhone and iPad Also use it to plan out trips                 Great App
To those who say that the map data is a old you have to understand that this app uses USGS data maps and is only as current as those maps it is a fantastic app There is an easy workaround for maps that Havel data once you open the topple map it will let you convert that map to satellite based terrain or Google maps orOpenStreetMap So like anyone ought to before you head into the backcountry you should always check your maps against current data this app gives you all the tools to do just that The ability to stitch maps together is a great asset No more do you get to the edge of one map and have to find your location on the next one just stitch the next map to your map and the data flows seamlessly Download times on WiFi are only a few seconds per map It will even shade the maps which turns them into a visual terrain identifying tool Im taking this tool into a nine day trip in the Allagash in Maine in September I will report more on how well it works afterwards Get this app learn to use it you will not be disappointed                 Phenomenal
I live in Hawaii and purchased this to help orient myself to the often bewildering views with all the mountain valleys I dont use it for offtrail hiking but when Im trying to figure out what I can see from my elevation or how far something is and its azimuth this is perfect Each time I open it I discover something new about the apps features and am glad I have this in my suite of maps                 Great for Hawaii
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 Ive 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                 Hunting hiking camping fishing
I use this app every time I head out backpacking Ive tried other topo apps more expensive than this one but this one works best for me Big fan                 This app is essential for backpacking
Great app if you are an outdoor enthusiast I used this app consistent as a GPS and map for my through hike of the john Muir trail Maps have to be downloaded while you have an Internet connection but the GPS on my phone worked well in areas that I had no cell service This app has gotten me out of a few situations where I was on the wrong trail I have also found many great off trail hidden gems while backpacking Love the app                 Great GPS
Please add the western Aleutians or dont claim to Cover all of Alaska I purchased this app for adak and now its useless to me        No western Aleutians
This app has replaced my Garmin topo maps Exactly like the paper maps only better because you can take them everywhere without the hassle of paper maps                 Excellent map app
Not sure why there are negative reviews for this App There shouldnt be If you actually know how to read a Topo then this is prefect If you need a babysitter then go find one I use this App for walkin hunting deep in the Ozarks and find it easier to use than my GPS An excellent feature about this App is the it will work when you do NOT have phone service unlike google                 Great App All Around
This is honestly one of my favorite apps and rightly earns a place on my home screen Its truly indispensable I cycled over 1000 miles around Washington state and 1500 miles down the Pacific coast back in 2009 and the app helped guide me every step of the way With my solar charger theres almost nothing I cant do with this app and features are constantly being updated as well Definitely worth the money                 An indispensable app
Used this app for some recent hunting and hiking Love it Thanks                 Great app
Believe it or not this is my very first app review despite being a long time iPhone user This app is so useful I felt I had to leave a comment I am a local hiker and weekend car camper who always likes to see the lay of the land using USGS Quads I love the resolution and feel of the old paper topo maps and this app captures it perfectly Not only can you view the quads you can view them in different orientations set and store waypoints adjust the relief appearance see radius scales and more This app is a dream in the field Im also a geologist so I use this app on the job too Awesome app                 Fantastic app
Very nice                 Awesome
Bought this to use while offroading and after first use Im thoroughly impressed Would only add route tracking to increase to 5 stars Great res on topos easy to download maps For those upset about old maps they are USGS TOPO maps and many are old Good maps even if they are old              Great App
Ive downloaded several maps and none are newer than 40 years old The map for Mount Rushmore area is from 1971     Extremely old maps
Whether Im hiking in the Ozarks or in the deserts and canyons in Utah I rely on this App to keep me on the trail I understand that USGS Topos vary in their update ages but I depend on the coordinates and contours more than anything else and those dont change much if at all                 Keeps me from wandering
Review for 113 3 stars Please fix all the scrolling on 6 Panning the map now glitches and jumps to random points on the map This problem did not exist in 112 I contacted Phil and he is working on a fix iOS8 screwed things up Review for 112 5 stars Talk about a simple and easy to use app Just make sure your device has a lot of space if you want to load up a lot of topo maps If you have a 16 gig iSomething you wont be able to load up a lot of maps unless you pull down the low res maps and who wants to do that I pulled down most of NY state and parts of 2 other states and Im already eating 45 gigs as of this review You do have the option to delete or downgrade maps Im not a fan that I cant launch or specify that I want to launch Google Maps if I have it but its not a show stopper Im limited to Apple maps and a few others A future where I can chose Google Maps would make this app perfect I can overlook some of the internal pages that feature early 90s UI buttons and such because the main interface is clean and looks good                 Simple UI and easy to understand
Ive 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 Im 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 Ive found is the lack of private property delineation                 Nearly perfect
I use this app all winter when Im hiking in the white mountains with no cell reception I hike about 160 miles per season in the whites and this app has coverage for most of the trails up there                 Love the app
In my opinion its just about the best one out there The tracking feature Im sure will come around soon                 Best
This app is sooo outdated its ridiculous The quad for my neighborhood is from 1967 I wish I could give you negative stars you deserve 3     Very poor APP
I have used this app more times than I can count to plan out and explore potential hikes I have used it on hikes to bushwhack on a heading I have used it to get an idea of exactly what kind of terrain I was in For 8 bucks this app is so worth having to me I recall it being cheaper when I bought it but that could just be my age working against me I have planned out routes and exported the KML I have imported KML for example all the parking and shelter locations along the AT I am sure other apps do this and some apps might have more upto date versions of the topo maps themselves but this does the job just nicely                 My Number One Map App
The maps do not have enough details but that is not problem with the app itself Otherwise it works well and is able to pinpoint location quickly even if there is no network access in the area           Pretty good for the price
This app is a must for the hunter camper hiker etc If you are an outdoorsmanwoman Topo Maps ties in the ability to look at the topo for an area plot your GPS coordinates and waypoints all without going back and forth between other programs Worth every penny hint read the instructional guide very helpful to navigate the program as there are a ton of useful tips and info                 Best yet
I think its a good app The fact that the maps are free if you will are good The biggest issue I have is the roads arent marked If you bought a map from your local store with a destination in mind and seen the roads arent labeled wouldnt it defeat the whole purpose           Roads
This is the absolute best topo maps in the history of the App Store its freakin amazing                 By far the best Ive used
I just returned from a backpacking trip and used this app to assist with navigation and trail finding The ability to download the topo maps for free from within the app is huge The GPS function is great and works in airplane mode We needed 4 maps for this trip and fortunately adjacent maps can be stitched together Sometimes some of the printing from the margin will still be visible when maps are stitched but that is a relatively minor complaint Ignore the reviews that complain about the old maps The reason for using the 1970s maps is the greater detail and more trails as explained thoroughly in the app details and on the website The complaints are mostly from people that didnt read the documentation and probably dont know how to use topo maps anyway This app is highly recommended                 Excellent app for hikers and backpackers
I love all of the features of this app especially the high res map downloads for offline use waypoints and distance functions Definitely worth the purchase I think a few minor improvements would go a long way for this app For example Connect multiple waypoints to form a path or trail Group waypoints and show them as layers Great app so far really anxious to see these improvements eventually              Extremely Useful
This is a great app I use it for hiking and have been very pleased with all of the features                 Great app
I found the images on the section I reviewed to be more than three years old I need more up to date information for our fast growing area Could you please refund my cost Thank you     Topo map App
Great app Cant beat it for the price for cost and maps available Would like a to zoom closer on maps on iPhone                 JimJaw
I use this on my iPod Touch instead of hauling around paper topos It is simple and easy to use The Mosaic feature which lets you create a seamless mosaic of contiguous topos is a particularly sweet feature Highly recommended                 Great for offline use
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 dont 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     Old Mapsnot good for hikers
This app is awesome however I would love to see more maps added such as historic topos and more USGS maps                 Love this app
Ive found some dirt roads missing One is the very road I live on in Idaho It should be there unless this is a very old map Seems like a pretty good app but I dont totally trust it advise to use with caution           Some missing roads
Ive used this for years and its easily the best topo app Ive seen Its great for scouting new property and going deep on public land to get away from everyone else                 Awesome app for hunting
Ive used this app for years without any crashes Wonderful topo map resource                 Just Fantastic
This is hands down the most helpful app in my phone Having the ability to use maps even when there is no cell connection is a lifesaver Works anywhere I am as long as I downloaded the maps before I left Only recommendation would be the ability to track your path Though that could potentially destroy battery life                 Best App Ever
I use this app constantly and its amazing I work in the field doing creek surveys and love how well its location function works even when I have no service on my iphone I can drop pins where Ive done a survey or where theres good creek access during reconn Thanks for such a useful app                 Most useful field app ever
Ive been using this app since 2009 and it has consistently been my goto for reference maps of areas that I hike andor fly fish in Its been with me thru Colorado Arizona and now Arkansas The ease of use and general features of the app are perfect for me when Im the back country especially since you can download the area youre in before you go and not worry about cell signal only battery life                 My goto Topo App
I bought this because it is suppose to be TOPO but it is really bad not like any Topo I own Just use google its free If you use TOPO why would I want to enter an address no you enter your God cords duh Horrible app want my money back     No Topo really old style map
Im disappointed with TOPO It lacks a lot of common trails or I can find them There is no Bandera Mt or Little Si           Missing Trails
This app is very simple and extremely useful Easy offline access to topo maps as long as you remember to grab the ones you need before you leave cell coverage UI could be a little slicker but the simplicity makes up for it              Simple and useful
The database is impressive but even at hi res the trails are impossible to make out Its nice to have access to so many maps but as a functional replacement for a physical map its useless I had better luck with PDF maps        Not worth the money
No complaints Simple and useful Thanks                 Well done very handy
Ive had this app for 4 years Use it everyday for my profession Quick download great inapp tools Have saved time and money with this app Highly recommend for Land Surveyors                 Amazing app
Ive used this app for backpacking in the Yosemite back country on and off trail for 4 years plus day hiking in many other areas and I have found it extremely useful The maps can be downloaded and used as part of the pretrip planning and icons placed on the intended route and for identifying features you might be interested in Since I am offtrail much of the time this was useful The maps are stored on the device so no WiFi or internet connection is needed The GPS feature also is quite useful and accurate as well The button has 2 settings If you tap it it will find you and lock to that location on the map but if you tap the button once it allows you to move the map around but the unique locator icon remains on your location If you tap it again it turns the GPS locator off Unfortunately one reviewer wasnt aware of this feature and gave the app a bad review It uses official US Geologic Survey 75 minute topographical maps with 40 foot contour intervals I mention this because one reviewer gave it a bad review because they werent topo maps Unfortunately the USGS doesnt update them anymore and while the terrain may not change much towns and roads do For the backpacking I do on and off trail this has never been a problem For me its an excellent and very useful app                 Extremely useful app
Topo Maps is so much more than simply a source for reference maps My personal thanks to developer Phil Endecott for providing a product that keeps our family safe during our frequent offroading trips in Southern Utah Once Topo Maps waypoints are preplanned for each route our dash mounted iPhone with GPS function then continuously pinpoints our progress on each map and any inadvertent deviations on the intended route As we travel adjoining maps then automatically open Especially helpful here where we have less populated and complex trail systems where it would be easy to get lost and possibly run out of fuel The most valuable tool we could have possibly brought along given my admittedly poor sense of direction Thanks again                 Unbelievable Value Free Maps
Amazing program                 Geologist
Maps for the area I was interested are based on aerial photos taken in 1960 not much use Would not recommend this app     Old maps
