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), embarked on the development of this tactical navigation platform immediately 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 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 Nett Warrior, ATAK, BFT, and other military targeting and navigation systems. Its accuracy is within 1mm of officially approved DoD equipment. 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. 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) • One-button night mode function for low-light situations • Apple Watch support included for free • ‘Go to Grid’ feature for precision planning, drawing of overlays, and dropping waypoints • iOS/iPadOS native code built for austere and contested environments IMPORTANT NOTES: The Department of Defense does not endorse Tactical NAV and 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.

Theodolite HD is a multi-function viewfinder that combines a compass, two-axis inclinometer, rangefinder, GPS, map, nav calculator, and geo-overlay photo/movie camera into one indispensable app. Theodolite was one of the very first augmented reality (AR) apps when it was released in 2009, and it’s been downloaded and used by millions of customers since then. Uses are endless, and the app is great for land measurements, outdoor sports, sightseeing, navigation, and finding your way around. Theodolite is a pro grade app and is used extensively by surveyors, geologists, architects, engineers, competitive sportsmen, first responders, military personnel, and search and rescue workers around the world. Theodolite lets you take data-overlay photos and movies with 2X-8X zoom. Overlay geographical data, angle markings, date/time, author/company info, and project notes directly on photos and movies for later reference. The same data is written into the metadata record of images, making image files self-contained data records. Third-party apps can tap into Theodolite's advanced camera functions with a camera sharing feature. View current position on the built-in map with optional offline Outdoors maps that include topo contours, roads, trails, landmarks, campgrounds, ski lifts, and more. Live map markers continually update distance/heading relative to the current location and also show wayfinding info in the main viewfinder. Draw polygons on the map to mark things like property boundaries and trails, and import/export polygon data via KML. Share map markers and nav calculator points with other users of Theodolite via text messages or e-mail. This powerful capability opens up a wide range of collaborative uses including team land surveying, accident investigations, spotting wild fires, triangulation of landmarks, and advanced tactical observation and targeting. With an optional in-app purchase to enable team tracking, you can share location with up to 20 people on Theodolite's map. Theodolite includes features for serious users like a reference angle mode, nav calculator, map marker import/export, manual and automatic data logging with CSV and KML export, clipboard integration, %grade display, mil compass readout, optical rangefinders (including a mil-based reticle, sniper-style stadiametric graphs, and a variable 4X-24X scope), and night filters to improve use in dark conditions. Theodolite can provide location in military grid reference system (MGRS) coordinates, Universal Transverse Mercator (UTM) coordinates, British/Irish National Grids, US National Grid, Maidenhead locator system, Map Grid of Australia, and six latitude/longitude formats. Optional US State Plane coordinates include SPCS27 and SPCS83 zones covering all US States. The optional Datum Pack adds over 230 geodetic datums to the app to improve position computation from GPS data, covering regions and countries on all continents around the world. AR Layers include navigational aids like the sun, moon, planets, and Polaris (North star), and the optional US Mountain Summits layer that shows over 70,000 US mountain summits in the viewfinder. Theodolite has been shown in Apple Keynotes, featured on the App Store, and has been a #1 selling Navigation app in App Stores around the world. Since its introduction in 2009, Theodolite has defined augmented reality navigation. The app continually introduces new technologies, pushing the limits of iOS app development and taking advantage of new hardware capabilities. Find out why Apple named Theodolite one of the most amazing apps available and showed it being used to explore the Great Wall of China. Where will you take it on your next adventure? Note: Theodolite HD is an iPad app -- see the regular “Theodolite” app for use on an iPhone or iPod Touch.
