This is Jon, the creator of TACNAV-X, an offline tactical navigation platform built for austere and contested environments. I sincerely appreciate you taking the time to check out the app. TACNAV-X is dedicated to the 24 Soldiers killed in action during our deployment to Afghanistan in 2010, and to the men and women who continue to serve today. I'm still here, I'm still listening, and I'm still building. God bless you, Jon --- KEY FEATURES: • Offline mapping capabilities (full app usage with no emission of a cellular signal) • Purpose-built for the individual Soldier • WGS-84 standard (MGRS, UTM, BNG, and USNG coordinates) • A military-quality precision targeting platform • 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 • ‘Go to Grid’ feature for precision planning and targeting • Snap and save photographs onto the main map to increase situational awareness • Location, waypoint, and photo-sharing capabilities (via email and text) • One-button night mode function for low-light situations • Apple Watch support included for free BACKGROUND: Built from the ground up in the rugged mountains of eastern Afghanistan, Tactical NAV (also known as TACNAV-X) 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 and Korengal Valleys of 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), began developing this tactical navigation platform immediately after 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 TACNAV-X, even to this day. 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 accomplish their missions at home and abroad. Tactical NAV officially launched on the App Store on February 14, 2011. BUILT FOR ACCURACY: TACNAV-X was extensively field-tested during military operations in Afghanistan and later at Fort Bragg, including comparative testing alongside the AN/PSN-13 Defense Advanced GPS Receiver (DAGR) and other military navigation systems. 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 undergone extensive real-world evaluation alongside Nett Warrior, ATAK, BFT, the DAGR, and other military targeting and navigation systems. During comparative testing, TACNAV-X demonstrated accuracy within 1 meter of a DAGR. IAPs & SUBSCRIPTIONS: Currently, offline mapping mode is available as a monthly or yearly subscription, or as a one-time purchase. Drawing mode, previously an in-app purchase, is now included free for all users. All revenue generated from these features contributes to further development and updates, and a portion of the proceeds are donated to charities that specifically benefit disabled veterans. IMPORTANT NOTES: The Department of Defense does not endorse Tactical NAV or TACNAV-X. The app should not replace a government-issued device during life-threatening or combat operations. SUPPORT: If you have any questions about the app, please contact Jonathan Springer directly at jon@tacnavx.com. ## Key features - Precision targeting platform - Offline mapping - Waypoint plotting with military graphics - Tactical drawing mode - Location and photo sharing - Compass FastLock function ## Pricing and in-app purchases Base price: $8.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Drawing Mode | $4.99 | one-time | | Offline mapping for 1 month | $9.99 | one-time | | Offline mapping for 3 months | $6.99 | one-time | | Offline mapping for 1 year | $24.99 | one-time | | Offline mapping for life time | $39.99 | one-time | ## Chart rankings - #8 in Top Paid · Navigation (US App Store) ## What do users think of TACNAV?

Each update makes the app better and more capable, and it’s clear you’re putting real thought into how it’s used in the field. Keep up the great work, and keep making those of us at Fort Campbell proud.

Thanks again, Captain. Keep it up. ~ Chief “Night Stalkers Don’t Quit!” ### 4/5 — Nice app *2026-05-06, version 5.0.11* Nice app ! I would perhaps appreciate altitude data and more drawing mode options, e.g. drawing spaces using coordinates, circles using radius, etc. ### 1/5 — Crashes *2026-05-02* Keeps crashing and loosing map overlays waste of money ### 5/5 — Superb 👍🏼 *2026-02-16, version 5.0.11* TACNAV-X is excellent.

I’m super impressed! ### 5/5 — Best app + customer support *2026-01-03, version 5.0.10* I wanted to share my thoughts about this app because I was impressed when Jonathan (Captain Springer) took the time to respond to my email about a couple new features he's working on. This app is excellent. I've verified its accuracy, which rivals the DAGR and Falcon View, and it’s accurate to less than a meter. My mortar guys have used TacNav-X to plan and verify targets during live fire training. All on target. Pretty BA. I completely recommend this app to anyone in the military. And for infantry dudes like myself, this app is an absolute necessity. ### 5/5 — Best app + customer support *2025-12-28* I wanted to share my thoughts about Tactical NAV because I was impressed when Captain Springer, the app's creator, took the time to email me directly in response to my inquiry about a new feature he's working on. Since Jonathan made the effort to provide me with a detailed response, I felt it was only fair to offer my honest assessment of the app. TACNAV is excellent. I've personally verified its accuracy, which rivals the DAGR and Falcon View, accurate to less than a meter. Some of my mortar guys have used this app to plan and verify targets during a recent FTX that involved some live fire training. I completely recommend TACNAV to anyone in the military, regardless of branch. However, for fellow infantry soldiers like myself, this app is an absolute necessity. **Developer response:** Hi Tiger, Brother, thank you for leaving such an amazing review. You don't know how much these mean to me. Please hit me up anytime if you ever have feedback for me and the team, or if you ever need help. Take care, brother! - Jon ### 5/5 — Built for Real-World Use *2025-12-24, version 5.0.10* Hi Jon, I just wanted to update my review and let you know the latest updates to the app are outstanding.

Jon here. I like to keep things real with you, so I appreciate you taking a moment to read this. As many of you know, I built this app downrange as a Field Artillery Captain in the Pech and Korengal Valleys of Afghanistan, and I’ve carried that mission with me ever since. TACNAV-X was born out of my commitment to honor the brothers we lost in 2010 and 2011. For me, this will always be more than software. It is a living tribute to their memory. They deserve nothing less. In this update, drawing mode is still completely free. It was previously an in-app purchase, but I don’t want there to be any barrier when you need it most, or for anyone to feel they’re being taken advantage of. Offline mapping remains available as a one-time purchase or subscription. That support is what allows me to pay my developers, maintain updates, and keep TACNAV alive. Nothing more. I’ll also be honest with you. I’ve been dealing with some significant health issues lately. Continuing to build and support this app is how I stay grounded and keep going. Bottom line, I appreciate the prayers, support, and well wishes during this time. If you have ideas, requests, or just want to reach out, you can always email me directly at jon@tacnavx.com.
