Land Nav Assistant App Comments & Reviews

Land Nav Assistant Positive Reviews

1st Time rating an app in 5 years of using App StoreAwesome app, saved me on the land Nav course. Would definitely recommend for ROTC, army purposes like setting up points. It even has an arrow that points in your point direction and displays the distance. Would definitely recommend.Version: 2.2

Works perfectly in the fieldOnly thing I would request is that the app only uses location when the app is open, not all the time. Right now it's either all the time or not at all.Version: 2.0

Great app but..Really great app simple to use and accurate would really wish it had a feature to save maps into the app itself to make loading faster (make it manual so it doesnt take up much space) and it would be amazing to get a iwatch app to make things easier..Version: 2.2

Easy to useNeeded to quickly plot about 20 points to verify land Nav course. Other resources were not time friendly. Pretty accurate location And compass. Point mapping Was the best part.Version: 2.2

Still missing something...I would give it 5 stars it is compatible with Apple Watch. That would be a dream come true..Version: 2.2

You rockBest one hands down. Now I gotta make sure these privates are not using it during land nav ha! Apple watch app next maybe. I'll pay for that.Version: 2.2

Useful to a PointI love the app and it’s been really useful at times; however, not being able to download the map overlays leaves some to be desired. OK app overall..Version: 2.2

AppreciationI can’t say enough good things about this app, i use it every day in my MOS. It is one of the most useful tools I have to help me accomplish my job. THANKS A LOT LAND NAV, YOU GUYS ROCK!!!!!!.Version: 2.2

GreatI have used this on several land nav courses and on military convoys. It works perfectly!.Version: 2.2

Great app but...Would appreciate an Apple Watch version of the app but it is the best at what it does..Version: 2.2

SavedThis app saved me from a lot of pain .... you guys are the real MVP.Version: 2.1

Fool ProofFool proof.Version: 2.1

AwesomeThere's no other app out there like this one. Just plug in ur grid of where your at and the grid of where you need to be and it literally tells you the azimuth u need to walk and for how long. And u can always change the grids at anytime! Devs if this app could get any better than what it is ie.( show line on Map from the different points to give us a better sound picture of a visual of how long the two or more points are from each other would be cool) as an option! All in all I recommend this to everyone!.Version: 1.0

This app is very functional but some improvements are welcomeFirst off kudos to you, the app works flawless, but here are some list of improvements , my job is dealing with maps so here are my wishes When getting location it would be nice if you made the app collect points continuously, for improving the accuracy , specially if you are in the woods, sometimes you could get faulty readings but, if let's say you stay in one spot and take points for about a minute and average them out it would be much more accurate, currently I don't think there is a app that does this Another is the compass, it would be nice if it showed you what was the azimuth to your next point from you current location and I would like the option for full screen. It would be wonderful I the app would show speed, and the path traveled When entering mgrs it would be nice to have 3 boxes one for current zone , then the others for x and y , which will make it much simpler when entering them.Version: 1.6

Great app works perfectlyThis app worked flawlessly for me. 8 digit grids are actually within 10m not 100 as a previous review stated (hence the reason it says accurate within 10m) and if you can't find a point standing within 10m of it, thick forest or not, then there isn't much hope for you anyway! Great app, love the feature where you can press on your points and it gives an arrow pointing where you need to go and how many meters left. Does exactly what it says no more no less..Version: 1.0

IOS 11I really enjoy having this application and I use it a lot being in the military, and it has never failed me! Please update your app to 64-bit so when the new iOS comes out. I can still use it. You don't have to do anything else, just upgrade that one part lol.Version: 1.8

Accurate to 15 metersOn Ft Knox with 10 digit grids, it got me within 15 meters on all my points but two. As a downside, I would be standing in front of the point and it'd say it was about 10 meters away, but I'm not complaining. Somehow it did it when I had no signal also, which was pretty awesome. Well worth the $2.Version: 1.2

The best app ever createdI NEVER write reviews. In fact this is my first and probably the only one I will ever write. This app took me directly to the plotted points with incredible accuracy. Land Nav course on Ft Hood with almost no reception and still this app pulled through. Highly recommend and kudos to the developer..Version: 1.2

Better than military issued equipmentCurrently on my 2nd deployment, I've used this during real life scenarios and haven't had a problem. Got grid coordinates in seconds. Works great outdoors. Might have direction issues when you're inside a vehicle but outdoors is great.Version: 1.6

Would be perfectWould be perfect if they had Apple Watch capabilities. I don't like having to pull out the phone. I would rather just use my watch. Please add this feature! I still love this app though. It's awesome.Version: 1.8

It's ok but.....I'm pretty darn good at land navigation but wasn't in the mood for it. So I downloaded this app...it's easy to use and it found 3 out of 4 of my points, but it left me stranded on my last point. Had me going in circles. I had to revert back to my trusty compass. So this is why I give y'all a 3 out of 5..Version: 1.8

Best App I've spent money on.If it weren't for this app I would be lost somewhere in Camp Atterbury, IN. I'm awesome at land nav but the advanced course there would have gotten me lost a thousand times over without this app. Works perfectly for ten digit grids. Found my points exactly..Version: 1.0

Great appI seldom ever write reviews, but this app is awesome. Easy to use, accurate even with 1 bar of reception. Even if you are skeptical I urge you to trust the app when you're on the ground, or use it to just double check where you are..Version: 1.2

ExcellentVery basic very simple very easy to use. Was exactly what I was looking for. Set waypoints or locations and with no internet service will tell you the heading you need to use to get there..Version: 1.8

App works. But doesn't.While the app does work, a 10 digit grid is actually an 8 digit grid when you have to input the grid designator. 8 digit gets you within 100m of your point. Which in thick forest looking for a specific point, a white ammo can in this case, is useless. If it was a true 10digit gps, this would be the best land nav app out there..Version: 1.0

Great appUsed this both before deployment and during. Works really well. Was able to pull up coordinates faster than my dagr, and got me to every point I needed..Version: 1.8

UserFrom my experience as a scoutmaster, land surveyor, and youth leader-- this is a great app for simple, reliable and accurate navigation outdoors or to off the grid locations Google Maps can't find..Version: 1.0

Definitely worth 5 stars for a free appWorks better than a DAGR! One improvement I would recommend is to put maps on there. Lots of them available free via USGS.Version: 1.8

Great ToolFound all points with 2HRs 30mins remaining of 5HRs. Though I had some distance to make, knowing the plotting and azimuth were correct made finding the points that easier..Version: 1.3

Works greatHad absolutely no problems with this app. Was able to navigate with it perfectly!.Version: 1.6

Outstanding!!Punch in the grid and your off. Gets you were your going with ease. Would recommend to anyone for assistance with land Nav..Version: 1.8

Tested multiple timesAlmost perfect accuracy. Simple and easy to use. I sprinted through my last land nav course and got 5 out of 5..Version: 1.0

Great App for Army Land NavigationI was hesitant on getting this app but after reading the reviews and testing this out at the Fort Hood Land Nav site Training Area 72, it was quite close to where the points were. This app is worth the money..Version: 1.6

Great ProductIt's a great compliment to the knowledge you should already have with regards to land nav. Easy to use. Would buy again..Version: 1.8

NavGood app..was a little nervous using at first. But I definitely had no issues found 10/10 points with it..Version: 1.6

ReviewWorked for my night course. Put me within 20 feet of the point every time..Version: 1.3

NEEDS TO BE UPDATED!!!I like this app but is now incompatible with the new iOS 10! I can't verify my points anymore by tapping on the pins! Please fix!! It's a paid app and customers shouldn't have to go through these issues!.Version: 1.8

Great appWould like to edit points and change colors of pins. 5 stars..Version: 1.8

Good appGood app was able to find all my points and used it twice with no problems. Highly recommend app for landnav course..Version: 1.8

Great app!Outstanding app! Used it during R&R on a hog hunt in Oklahoma to get to all the different stands...worked perfectly. Just plugged in the grid coords & took off!.Version: 1.3

Simple, perfect and now even better!Simple app, but it does exactly what it says. Coordinates are dead on..Version: 1.6

Great App!This app is freaking awesome! Hands down, if you're in the military, this app is for you. Very accurate, just plot and go. Hoah!.Version: 1.2

Great App!If you are military this app is for you! It really puts you right on top of your point.Version: 1.2

MGRSStrongly recommend this app it is right on target for the price it will amaze you don't look any farther.Version: 1.2

Awesome!With this app it's pretty much impossible to get lost! Seriously, thanks!.Version: 1.8

Land NavWorks really well for the money you pay for it..Version: 1.8

ExcellentDoes exactly what it says. Simple and easy to use. Reallllllly helped me in the woods recently.....Version: 1.2
