About this app

Created to save military lives, Tactical NAV was the first MGRS-focused app on the App Store and is the only tactically-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 mobile-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), who was on his third combat deployment, began developing the tactical-navigation platform following the memorial services for Spc. Blair D. Thompson and Spc. Jared C. Plunk, 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 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 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 navigation 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 the utmost accuracy and reliability
• Android 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 combat situations in place of a government-issued device.


For users who have purchased Tactical NAV in the past, please email us and we will take care of you directly and issue you a refund so you can download the new version.

This application is awesome. And they have made many improvements. But it still has one very frustrating bug when used on the Android platform. It locks up all the time. It takes for ever to do whatever it does to unlock, so it takes time to use.

Hi Thomas, thanks for your review, and I appreciate your feedback. I promise I'm working on ironing out the bugs and crashes that are occurring and am working behind the scenes on this stuff now (identifying which Android phones are having problems and addressing them). Thanks so much for your support, and have a great day. Take care! - Jon

Option for graphics and free draw are great, but the app crashes pretty frequently. Use interface is not intuitive, difficult to figure out how to save overlays. Offline maps should be an option in Android for the price paid. Crashes when trying to open gpx files.

This version seems to have much more functionality than the last one. I was very disappointed as a long time user of the previous version to find out that the update was released as a new product. Nothing like paying for something a second time. 5 star application, minus one for making me pay again.

Hi Lyle, thanks for leaving such an excellent review for the app. Please contact me at jonathan@tacticalnav.com, and I'll take care of you ASAP since you purchased the older version. Bottom line, I had to release a new version of the app because I rebuilt the code from the ground up (sorry about that). Take care, and thanks for your support! - Jon
