Created to save military lives, Tactical NAV was the very first MGRS-focused app on the App Store, and it is the only battle-proven app commercially available today.


Built from the ground up in the rugged mountains of eastern Afghanistan, Tactical NAV comes from the mind of a U.S. Army Field Artillery officer who had a vision of creating a low-cost and highly accurate tactical navigation platform built specifically for military service members.

Tactical NAV's journey began in the notorious Pech River Valley of Kunar Province, Afghanistan.

U.S. Army Capt. Jonathan J. Springer, a Fire Support Officer with the 101st Airborne Division (Air Assault), began developing the tactical navigation platform following the memorial services for Spc. Blair D. Thompson and Spc. Jared C. Plunk, who were killed in action on June 25, 2010.

After pitching the idea and being turned away by the Department of Defense on multiple occasions, Captain Springer remained resolute in his mission to continue developing Tactical NAV — even to this day. His ultimate goals were (and still are) to make a difference for other Soldiers and honor the men and women who were killed and wounded in battle.

He ended up using his life savings to continue moving forward with the Tactical NAV project, all with the ultimate hope of saving military lives and helping his fellow service members accomplish their mission at home and abroad.

Tactical NAV officially launched on the App Store on February 14, 2011.


Tactical NAV's mission is to provide military service members a low-cost, highly accurate, and exceedingly powerful mobile tactical navigational solution.


Our vision is to assist and support our nation's service members with their mobile navigational needs and further enable them to operate and win during Multi-Domain Operations (MDO).


Tactical NAV's performance is on par with the AN/PSN-13 Defense Advanced GPS Receiver (DAGR), and it has the feedback to prove it.


Purpose-built by Soldiers and created to save military lives, Tactical NAV was the very first MGRS-focused app on the App Store. It has proven to be effective across a multitude of environments all throughout the world.

Tactical NAV has been successfully evaluated against other software platforms and devices such as Nett Warrior, JCR, BFT, JBC-P, and ATAK. Its accuracy is within 1-to-3 meters of these officially approved systems issued by the Department of Defense.


Tactical NAV contains in-app purchases (IAPs) and subscriptions. Currently, tactical drawing mode is available as an in-app purchase, and offline mapping is also available to users as either a monthly or yearly subscription. All revenue generated from these features goes towards further developmental coding and updates, and a portion of all proceeds are donated to charities that specifically benefit disabled veterans.


• A military-quality precision targeting platform
• Purpose-built for the individual Soldier
• Offline mapping capabilities (complete usage of the TACNAV platform with no emission of a cellular signal)
• WGS 84 standard (MGRS, UTM, BNG, and USNG coordinates)
• Tactical drawing mode (e.g., useful for Joint Fires planning, creating overlays, route planning, and so forth)
• Waypoint plotting functionality with military graphics (per FM 1-02.2)
• Compass "FastLock" function for capturing quick azimuths
• Snap and save photographs onto the main map for intelligence purposes and AARs
• Location, waypoint, and photo sharing capabilities (via email and text)
• One-button night mode function for low-light situations
• "Go to Grid" option for intelligent pinpoint planning and drawing of overlays
• Created and tested to ensure utmost accuracy and reliability
• iOS native code built for austere and contested environments
• And so much more!!!


The Department of Defense does not endorse Tactical NAV, nor should it be used in life-threatening or combat situations in place of a government-issued device.

Tac Nav is a keeper…

Man, Ive used Tactical Nav for years serving in the military. Ive utilized this app on deployments to Afghanistan, Saudi Arabia, and its been used at home during training. Tac Nav is always an app i can depend on, it’s dead accurate, and the features that have been added to it over the years have been awesome.

Like other reviewers have said, Tactical Nav can use a horizontal option, but Ive emailed the devs about it and they responded back to me the same day and told me that they’re working on it. So thanks for the great customer service guys, and for the support and work you put into the app. Offline maps is a game changer, IMO. Its been the biggest feature that me and my guys use when we operate in areas where there’s no signal. It also helps with OPSEC because we can completely use the app while it’s in Airplane mode.

To the developers: Please keep up the great work with Tactical Nav and continue pushing ahead with the updates. This app has really been a life saver for me and my guys when we’ve needed it. Highly recommended. Always forward!

Developer Response ,

Potato Demon,

First of all, I love the username. Secondly, thanks for leaving such a thorough and fantastic review for Tactical NAV. I can't begin to describe how much it's appreciated, so thanks.

Like I said in my email, I'm tracking the need for a horizontal/landscape option for the app, and we're coding it in now (it just takes time since the UI/UX is customized). We're also working on some more updates that will follow soon, so please be patient and stand by.

Also, I'm thrilled to hear that the app was beneficial to you and your guys when you were deployed overseas. Offline mapping mode was the most significant update that we've integrated into the app. So I'm happy it has worked out for you when you've needed it.

Bottom line, if you ever need anything else from me or have additional input and guidance for my development team, please send me another email anytime. I'll do my best to incorporate your feedback into Tactical NAV in the future.

Again, thanks for the great review, and I genuinely appreciate your support. Take care!

City use / Hiking uses

This app isn’t just deployable to war zones! I am a prior Army Sergeant who loves to go out into the wild and I don’t always grab my Garmin but I always have my phone! With this app I can feel at ease knowing I have the technology to find my way out of the thick of it if I get turned around! The map is as easy to view as those such as google and maps by Apple. If you are in city limits there is even store names and very detailed mapping of the area streets and side alleys!

On the military side of this, the owner takes the lives of Soldiers very serious and created this to ensure those lobbing rounds down range had the best tool available to ensure call for fire was as accurate as possible to ensure the lives lost were the intended targets and to ensure those who called it in got the protection they needed! He didn’t create this app just for a dollar sign, he would put the lives saved and protected by the accuracy of his app over any amount of money, that’s the kind of guy who is putting his life into this!

Great app for diverse utilization!

This app is such a user-friendly platform where the everyday civilian and soldier can easily access and utilize accordingly. As a civilian traveling across various rural areas and cities in the US, this app has never failed me. I have navigated the busy streets of NYC and LA with this app, and then found my way around the less populated Midwest rural areas of Iowa and Ohio.

As a fires intelligence officer, there is no better innovation that is easily and readily available that I would trust more. The offline capabilities is truly a lifesaver where the dictating battle environment may present those complex scenarios. This app provided our artillery batteries and the chain of command the necessary information to send rounds down range in a timely and accurate manner that saved lives! Today’s technological capabilities provides such innovative opportunities for commanders and our most senior leadership....this app answers those calls to be a cost effective and reliable resource!
