Description
BACKGROUND:
Created during a combat deployment to Afghanistan in support of Operation Enduring Freedom (OEF), Tactical NAV was developed to honor the soldiers who made the ultimate sacrifice. As the first MGRS-focused navigation app available on all app stores, it serves as a tool to enhance soldier safety and mission success, built with the memory of fallen comrades at its core.
Built from the ground up in the rugged mountains of eastern Afghanistan, Tactical NAV was developed by a U.S. Army Field Artillery officer with the vision of crafting a low-cost and highly accurate mobile navigation platform tailored for the U.S. military.
Tactical NAV’s journey began in the Pech River Valley in Kunar Province, Afghanistan.
U.S. Army Capt. Jonathan J. Springer, a Field Artilleryman serving as a Fire Support Officer with the 101st Airborne Division (Air Assault), embarked on the development of Tactical NAV following the memorial services for Spc. Blair D. Thompson and Spc. Jared C. Plunk, who were killed in action on June 25, 2010.
Despite initial rejections by the Department of Defense, Captain Springer remained steadfast in his mission to continue developing Tactical NAV — even to this day. His ultimate goals were (and still are) to make a positive difference for other soldiers and service members and to honor the men and women killed and wounded in battle.
He used his life savings to fund and develop TACNAV-X, all with the ultimate hope of saving military lives, and helping his fellow service members in accomplishing their missions at home and abroad.
Tactical NAV officially launched on the App Store and Google Play on February 14, 2011.
BUILT FOR ACCURACY:
TACNAV-X’s performance accurately matches that of the AN/PSN-13 Defense Advanced GPS Receiver (DAGR).
MISSION:
Empower military service members with a highly accurate and powerful mobile navigation platform.
VISION:
Assist and support our nation’s service members with their mobile navigational needs and enable them to operate and win in both training and combat environments.
BOTTOM LINE:
Tactical NAV has successfully undergone evaluation against other software platforms and devices such as Nett Warrior, ATAK, and BFT. Its accuracy is within 1mm of these officially approved systems issued by the DoD.
IAPs & SUBSCRIPTIONS:
Tactical NAV offers in-app purchases (IAPs) and subscriptions. Currently, tactical drawing mode is available as an in-app purchase, and offline mapping mode is also accessible to users as either a monthly or yearly subscription.
All revenue generated from these features contributes to further developmental coding and updates, and a portion of the proceeds are donated to charities that specifically benefit disabled veterans.
KEY FEATURES:
• A military-quality precision targeting platform • Purpose-built for the individual Soldier • Offline mapping capabilities (complete usage of the app with no emission of a cellular signal) • WGS-84 standard (MGRS, UTM, BNG, and USNG coordinates) • Tactical drawing mode (useful for mission planning, building overlays, targeting, etc.) • Waypoint plotting functionality with military graphics (per FM 1-02.2) • Compass “FastLock” function for capturing quick and precise azimuths • Snap and save photographs onto the main map to increase situational awareness • Location, waypoint, and photo-sharing capabilities (via email and text) • ‘Go to Grid’ feature for precision planning, drawing of overlays, and dropping waypoints • Android native code built for austere and contested environments
IMPORTANT NOTES:
The Department of Defense does not endorse Tactical NAV and TACNAV-X, nor should it be used in life-threatening or combat situations in place of a government-issued device.

*A Note from Jonathan (Creator of Tactical NAV)*
What’s up, guys. Jon here.
This app was built out of my commitment to honor the soldiers we lost in Afghanistan in 2010 and 2011.
For me, this will always be more than software — it's a living tribute to their memory. They deserve nothing less.

Excellent GPS and tactical military app. Will be utilizing this on jumps and field ops. Offline mapping works as described and the app, overall, is very easy to use. Recommended.

This is my son's app. He created this app during his combat tour to Afghanistan after two of his soldiers were killed. He continues developing Tactical NAV in honor of his fallen soldiers, and he also donates proceeds from the app to disabled veterans. Jonathan has given his heart and soul into making this app available for other soldiers, and it's his way of giving back to the military community. We love you son, and dad and I are proud of you!

Not very user-friendly. Doesn't allow you to delete things easily. Created an entire overlay and wanted to delete one drawing. Had it selected but kept saying I must select at least one event. Deselected and it deleted my entire overlay. Creator is overthinking it too. All these military symbols but not a standard CP symbol. No one is creating a BN overlay on this thing. Do the simple things right before trying to create a complex nav app.

Not at all what I thought it would be. From my experience so far the android version is subpar to that of the iphone. I've had the app for roughly 1.5 weeks, tried opening it today to work on an order, and it won't open. Force stoped it, restarted my phone, reinstalled the app. Nothing has worked.

It took years after purchasing this app for the developers to finally make it work for Android. THEN I had to pay for it again because...you know...screw me, right? Now it crashes every time I try to open it and won't even open to the first screen. I'd demand my money back, but I don't expect these guys to have any kind of urgency in doing it. I'm a veteran like them and am really disappointed by these brothers in arms. Waste of money, full of frustration, no follow through from the developers.

Was using this app as an OC at Ft Irwin. Worked well for a while, albeit location lock was a little laggy. However, app will now randomly wipe out all saved nav points and now no longer locks onto my position
