Land Nav Assistant is the kind of tool that makes most sense to someone who already carries a compass and a map sheet. It takes MGRS or latitude and longitude coordinates and walks you toward each point, showing distance, direction, speed and bearing as you move. It was made for soldiers and others in the armed forces, and that audience shows in everything from the grid overlays to the pace count analysis.
At $2.99 with no ads and no in-app purchases, it is a straightforward purchase rather than something you try and then decide whether to keep paying for. More than 50,000 installs and a 4.1 average from 341 ratings is a reasonable sign that a niche navigation utility does what it promises. It has been on Google Play since January 2012 and was updated in August 2026, so the developer is still working on it.
What appeals to me most is that it does not try to be a general-purpose map app. It is built around a specific job: getting you from where you are to a coordinate you have written down, in the format the military actually uses.
Coordinate formats and how you enter them
The app accepts 8-digit and 10-digit MGRS, latitude and longitude in decimal, latitude and longitude in degrees, minutes and seconds, and map input. That covers the formats you are likely to be handed on a range card, in a briefing or in a set of instructions from a teammate. DMS entry follows the DD:MM:SS pattern followed by a direction letter, with north and west as the defaults.
Angles can be shown in degrees or mils, distances in meters and kilometers or feet and miles, and speed in kilometers or miles per hour. These are small choices, but they matter when you are working alongside people who use one system and you use another. Being able to switch rather than convert by hand saves a step and a possible mistake.
You can also place points directly on the map. A long tap anywhere gives you the coordinate for that spot, and new locations can be added through the map interface. When you have a list of points to work through, you can order them yourself or let the course optimization tool work out the shortest path between them. Tapping the line drawn between two points gives you the distance and direction between them, which is useful for checking a leg before you walk it.
Locations can be displayed as 10-digit MGRS, 8-digit MGRS or decimal latitude and longitude, so the same point can be read in whichever format your paperwork uses. For anyone who has ever copied a grid reference onto a notepad and then second-guessed a digit, having the app hold the point and show it back in the format you need is a quiet but real convenience.
Maps, grids and what you see while moving
Navigation happens either through a simple arrow interface or on a map, and the app keeps distance, direction, speed and bearing visible as you go. The arrow view is the one I would expect to use most on the move, since it points you toward the selected point without asking you to read a map while walking. The map view is where the planning happens.
Four map types are available: satellite, terrain, road and a basic topographic layer. On top of any of them you can overlay a 1000-meter or 100-meter MGRS grid, which is the feature that ties the whole app back to paper map work. Seeing your position against a grid you recognize is a good way to confirm that the coordinate you entered is the one you meant.
The app also displays the distance and direction from your current location to every point in your list, or between any two points you choose. That makes it easy to see at a glance which point is closest, or how far apart two objectives are, without doing the arithmetic yourself. For a squad or a small group working through a series of points, that overview is more useful than a single bearing.
The compass work got attention in the most recent update, which mentions a smoother and more accurate compass and headings that no longer stick when you are standing still. I have not used this build, so I can only report what the developer lists, but those are the kinds of fixes that matter in a navigation app, where a heading that freezes at a stop can send you off in the wrong direction.
Planning a course and sharing the results
Beyond single-point navigation, the app is set up for working through a route. You can arrange points in the order you want to visit them, or hand that job to the course optimization tool, which calculates the shortest path through the set. On a training course with half a dozen points spread across an area, that is the difference between a sensible route and a lot of unnecessary walking.
Your location list is not trapped in the app. It can be downloaded as a spreadsheet, which you can save or pass on to whoever needs it. There is also a web import utility on the developer's site for bringing in a large batch of locations at once, which is the practical way to load a full course rather than typing each grid reference by hand.
Together these two features suggest the app is meant to be part of a workflow rather than a standalone gadget. It suits people who already have their points worked out elsewhere and want to bring them in, walk them, and export what they recorded. That is a more useful shape for a navigation tool than a list you can only read on one phone.
What you need before you start
There is no subscription to manage. You pay $2.99 once, and the app contains no ads and no in-app purchases. A one-time price with nothing nagging you on screen is easy to appreciate in a tool you might rely on outdoors.
The app warns against using it while you are still learning. The developer treats navigation as a skill to be mastered first and warns against relying on the app alone, particularly if you are lost. I read that as a statement about the app's role rather than a hedge. It is a tool for people who already know how to read a map and use a compass, and it assumes that knowledge rather than teaching it.
The same caution applies to awareness of your surroundings. A phone screen is not a substitute for looking where you are going, and the app's own guidance says as much. Anyone expecting an app that holds their hand through unfamiliar terrain should take that warning seriously.
Analyzing your own technique
One of the more interesting uses the developer describes is correcting your land navigation technique by looking at your pace count and your tendency to drift left or right. That is a training function rather than a navigation one. If you walk a leg and end up off to one side of your intended point, the app gives you something to examine afterward.
This is where the app separates itself from a plain coordinate reader. This one also gives you a record of how you got there. For someone preparing for a course, a selection or a qualification, that feedback loop is the part worth paying for, because it turns a walk into practice you can actually learn from.
It follows that the app rewards a certain kind of user: someone who wants to understand their own habits rather than just arrive at a point. If you are the type to note your pace count on a range card and compare it later, this feature will feel aimed at you.
Who gets the most from it
The clearest fit is military personnel and others who work in MGRS as a matter of routine. Army and Marine users are named directly by the developer, and the coordinate formats, grid overlays and mils option all point the same way. If your day involves grid references, this app speaks your language without translation.
Outdoor enthusiasts who have learned map and compass work are the second group. Hikers, land surveyors and anyone who plans a route through a series of waypoints can use the course ordering, the map overlays and the spreadsheet export. The app assumes you already understand the underlying skill, so it suits people who have put in that time.
It is a paid, focused tool rather than a free general-purpose map app, and the developer's own warning makes the intended order clear: learn the skill first, then use the app. Readers who want something to teach them navigation from scratch are looking at the wrong product, and the app is honest about that. For everyone else in its target audience, the combination of MGRS support, course planning and export makes a strong case at this price.
A focused tool for people who already read a map
Land Nav Assistant does one job and does it in the formats its audience uses.
Its limits are the limits of its purpose. It is built for people who already know land navigation, and the developer says plainly not to use it while learning. The coordinate formats, the mils option and the pace count analysis all assume that background. If you have it, the app looks like a well-considered companion for training and for work in the field.
For military personnel, outdoor users with map and compass experience, and anyone who needs to move between a list of grid points and keep a record of it, this is an easy recommendation.
The short verdict
A focused, fairly priced MGRS navigation tool for people who already know map and compass work.

Land Nav Assistant: frequently asked questions
What coordinate formats does Land Nav Assistant accept?
It takes 8-digit and 10-digit MGRS, latitude and longitude in decimal, latitude and longitude in degrees, minutes and seconds, and points entered directly on the map. Degrees, minutes and seconds follow the DD:MM:SS pattern with a direction letter, and the default direction is north and west. You can choose to display your saved points as 10-digit MGRS, 8-digit MGRS or decimal latitude and longitude.
How does the course optimization tool work?
You build a list of points and either order them yourself or let the tool calculate the shortest path through them. Tapping the line between two points shows the distance and direction for that leg. It is aimed at planning a route through several locations rather than navigating to a single one.
Can I get my locations out of the app?
Yes. You can download your locations as a spreadsheet and share or save it as you like. There is also a web import utility on the developer's site for bringing in a large set of locations at once, which is faster than entering them one by one.
Does the app cost anything or show ads?
It is a paid app at $2.99. There are no ads and no in-app purchases, so the purchase is the only cost involved.
Can beginners use it to learn land navigation?
The developer advises against using the app while you are learning land navigation, describing the skill as one to master first. It also warns against relying on the app alone, especially when you are lost, and reminds users to stay aware of their surroundings. It is best treated as a tool for people who already know how to read a map and use a compass.
