TacMap is an offline map for the field: unlock once, with no subscription. No TacMap account, ads or behavioural analytics. Built for hiking, hunting, overlanding, search and rescue, surveying and MGRS navigation. MAPS WITHOUT A CONNECTION • Import PDF, GeoPDF and MBTiles maps and keep several to switch between. • GeoPDFs are placed in the sheet's own projection and datum, so the MGRS grid lines up with the printed grid. • Calibrate a plain PDF, including a scan or photo of a paper map saved as PDF, from three or more grid references (MGRS, UTM or latitude/longitude) and see how accurate each one is. • Maps stay sharp as you zoom in, and can be saved as offline tiles. • Use imported maps offline, without country restrictions. • Online basemaps, terrain elevation and weather are optional and require a connection. NAVIGATE AND PLAN • Read your position in MGRS, UTM or latitude/longitude. • Keep the map North Up or rotate it with your heading. • Measure distances, areas and bearings in degrees or NATO mils. • Add waypoints, draw lines and areas, and organise them into layers. • Use search-and-rescue, points-of-interest, airsoft and NATO APP-6 symbols. • Record your route and export GPX tracks. • See the elevation profile and line of sight along any line. Uses online lookups. • Red night mode protects your night vision. • Offline sun and moon times, and range rings around any symbol. WORK TOGETHER • Share drawings and symbols with your team over end-to-end encrypted Unit Sync. • Optionally share your callsign, position and heading with your unit. • Send encrypted text or reports to the room or a selected live unit with TacMap Chat. • Screen-off location sharing has a separate switch. Updates depend on the operating system and connection. • The relay cannot decrypt mission content, but sees admission, routing, session and control data, Chat recipients, IP addresses, timing and data size. “Routed” is not delivery or read proof; member status is relay-reported. YOUR DATA, YOUR TOOLS • Import and export GeoJSON, KML and KMZ, for QGIS, Google Earth and ATAK. • Export mission objects together; recorded tracks remain separate GPX files. • Mission data is encrypted in app-private storage. Imported maps remain in private, device-protected storage. • Online basemaps and lookups are off at first launch and can be enabled independently. While enabled, providers receive your IP address and requested map area, search query or coordinates. Coordinate and mission search stays on-device. • Optional Face ID or Touch ID app lock. For iPhone and iPad. ENGLISH AND GERMAN Choose English, German or Device language in Settings. Your own names, notes and messages remain unchanged. UNLOCK ONCE Try TacMap free for three days, then unlock with a one-time purchase. No subscription. The App Store shows your local price. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Unlock App | $4.99 | one-time | ## Version history (last 5 releases) ### 3.0.4 — 2026-10-07 TacMap 3.0.4: fixes and hardening • App Lock and the privacy screen now also cover open panels. After the privacy screen briefly covers the app, for example when you open Control Center, the keyboard and VoiceOver come back where you were. • Sturdier PDF reading, so a damaged PDF can't stop TacMap from opening. • Fixed rare cases where updating from TacMap 2.x could hide or remove imported maps. If TacMap was closed while recovering your map library, maps are no longer listed twice afterwards. • MBTiles packs that store their tiles as a view (for example from TileMill, MapTiler or tippecanoe) now open, and large packs open in the background. • Sturdier MBTiles reading: a damaged or crafted pack can no longer make TacMap close at every launch, and more packs built to use too much memory are refused before they are opened. • TacMap now tells you when an MBTiles map pack can't be opened. If your saved pack is missing, has changed or won't open, the map stays blank with a notice instead of loading an online map in its place. In Layers you can delete it, or try again if it just won't open. • Choosing a map in Layers and deleting it before it opened no longer leaves the map blank. • If the saved map library is missing, TacMap now says so instead of mentioning a recovery copy that doesn't exist. No map files are deleted. • With mission data protected by Face ID or your passcode, work that finishes after you leave the app no longer asks for Face ID or stops Unit Sync. Map imports and offline tiles that finish while TacMap is locked are saved once you unlock, and unlocking while a map is still importing no longer removes it. • Unit Sync: Undo no longer overwrites a teammate's newer change. • Unit Sync: in older-style rooms (join codes starting with 2:), objects no longer disappear when a teammate on iPhone still uses TacMap 2, and the room now explains that members on different app versions can see different objects. • Security hardening for the Unit Sync relay. ### 3.0.0 — 2026-10-02 TacMap 3.0 MAPS • GeoPDFs are placed in the sheet's own projection and datum, so the MGRS grid sits on the printed grid. USGS US Topo sheets import correctly again. • Calibrate a plain PDF or a photo of a paper map: put the crosshair on a grid intersection, enter its reference in MGRS, UTM or latitude/longitude, and see how accurate each point is. Move, edit or undo points, and pick up where you left off. • Imported maps stay sharp as you zoom in, with no gaps while the map loads. Save a sheet as offline tiles, and keep several maps to switch between. • MGRS grid labels match their lines, 10 km and 100 km lines follow the curve of the projection, and the grid stays tidy at zone edges. FIELD TOOLS • Elevation profile and line of sight along any measured or drawn line, with dead ground greyed out. Uses online lookups. • Night mode: a red, dimmed screen that protects your night vision. • KML and KMZ export for Google Earth, ATAK and GIS tools, with symbol images. • Hold the map for a point menu: place a symbol, measure, add range rings, see sun and moon times or copy the coordinate. • A guided tour of the map controls, and range rings that follow their symbol. UNIT SYNC • Steadier on poor connections, quicker to reconnect, and lighter on battery while you stand still. • Undo no longer reverts a teammate's edits. ### 2.1.0 — 2026-09-28 • Range rings: add up to 10 rings at your chosen spacing around any symbol. They sync, export and undo like other drawings. • Sun & moon: nautical and civil twilight (BMNT/EENT, BMCT/EECT), sunrise, sunset, moonrise, moonset and moon illumination for the map centre, calculated offline. • Sort the symbol list by newest, name, distance from the crosshair, affiliation or layer. • Keep screen on: an optional Display setting stops the screen locking while TacMap is open. ### 2.0.2 — 2026-09-19 - Imports custom symbol packs. - Improved translations for German. ### 2.0.1 — 2026-09-17 German translation/localisation. ## Apps similar to TacMap | App | Rating | Price | Category | | --- | --- | --- | --- | | [FieldGrid: Military GPS & MGRS](https://appshunter.io/ios/app/fieldgrid-military-gps-and-mgrs/id6761104187) | — | Free | Navigation | | [Red Grid MGRS - Military GPS](https://appshunter.io/ios/app/red-grid-mgrs-military-gps/id6759629554) | 4.4 (11) | Free | Navigation | | [MapNero](https://appshunter.io/ios/app/mapnero/id6758651027) | — | Free | Navigation | | [FieldNav: MGRS & UTM GPS](https://appshunter.io/ios/app/fieldnav-mgrs-and-utm-gps/id6776675118) | — | $2.99 | Navigation | | [Vera MGRS](https://appshunter.io/ios/app/vera-mgrs/id6760157283) | — | Free | Navigation | | [MilMap: Maps & Navigation](https://appshunter.io/ios/app/milmap-maps-and-navigation/id6788657368) | — | Free | Navigation | ## More apps by Christian Brooker - [Carrot Codes](https://appshunter.io/ios/app/carrot-codes/id6782497129) All apps by Christian Brooker: https://appshunter.io/developer/484019214 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
