## What is TacSync?

Put your whole airsoft team on one live map. See where everyone is, drop markers, draw plans and chat, in a private session only your team can see.

Built for milsim games that run for hours: TacSync keeps sharing your position with the phone locked in your pocket, and reads new markers out in your headphones so you don't have to take it out.

NO SETUP, NO SIGN-UP
Create a session, show the QR code, and your team is on the map. No TAK server to run, no accounts to hand out. Sharing stops when the game ends.

WHAT YOU GET
• Live positions: every teammate on one map, updating every few seconds, in the foreground and with the phone locked
• Markers, routes and zones: objectives, rally points, enemy sightings, patrol routes, boundaries and no-go zones everyone sees at once
• Squad chat: text, photos and voice messages in one session chat. Every new marker is posted there, one tap from the map
• Voice alerts: hear new markers, enemy sightings and injured teammates in your headphones, with direction and distance
• Squads and status: split the session into squads and mark yourself hit so your team sees it
• Briefing: pin the op briefing where every player can open it before and during the game
• Overlays: photograph the organiser's printed or hand-drawn map and pin it onto the real one
• Maps: satellite imagery, contour lines for the terrain and a live rain radar
• Distance: measure to the objective, a teammate or any marker
• Command post: run the game from a laptop at app.tac-nav.com with the whole team on one big screen

SEE IT FIRST
Tap "Start with a demo" on the home screen: three squads moving, markers going down and radio chatter in the chat, playing out live. Your own location isn't shared in the demo.

BUILT FOR PATCHY SIGNAL
TacSync needs mobile data to keep the team in sync, but fields drop in and out of coverage. A message or marker sent in a dead spot isn't lost: it waits on your phone and goes out the moment you're back in range.

PRIVATE BY DESIGN
Sessions are invite-only. Only the people who joined can see positions, markers and chat, enforced on the server, not just hidden in the app. After the game, everyone who played keeps the full record for the debrief.

COOPERATIVE, NOT COMPETITIVE
Everyone in a session is on the same side. No hit detection, no scoring: just shared awareness for your squad or your whole side.

## Version history (last 5 releases)

### 1.1.9 — 2026-10-15

New TacSync app icon.

• Your own position shows the moment GPS comes back, even after thick forest or with no mobile signal.
• Small fixes.

### 1.1.8 — 2026-10-15

Tacnav is now TacSync: same app, same sessions, new name.

• Opens with no signal: your sessions, the map and saved offline maps work even when you restart the app in the field.
• Fixed players being signed out mid-game and having to rejoin the session.
• Faster reloading after a weak-signal spell.

### 1.1.7 — 2026-10-06

• NATO map symbols: mark units, positions and objectives with standard military symbols.
• Custom squads, with their short name shown inside each player dot.
• MGRS grid on the map, and search by grid reference.

• Line of sight: see which ground is visible from any marker or teammate.
• Height profile along drawn routes.
• Sectors: show which way a teammate or marker is watching.
• Tap a teammate in the member list to open their details.
• Voice alerts speak distances in feet and miles when you use imperial units.
• More reliable GPS sharing in the background, and many fixes.

### 1.1.6 — 2026-10-02

• Meshtastic radios: pair a Meshtastic LoRa radio (Menu > Radio) and your team keeps sharing positions, markers, lines and chat where there is no mobile signal. Phones that do have signal pass everything on to the rest of the session.
• Measure distance: long-press the map and pick Distance, or measure to any teammate or marker. Only you see these lines.
• Tap a teammate on the map to see their details and actions. Marker and teammate cards are redesigned and follow light and dark mode.
• Live positions stay fast in large sessions.
• Fixes, including a first-launch error some new players saw.

### 1.1.5 — 2026-09-30

• Invite QR codes now work for everyone: scanning one with the phone camera opens a page that launches Tacnav, or helps new teammates install it or join from a browser.
• Notifications now arrive in your app language.
• The map opens on your team and markers instead of a default location.
• The live demo is now a quick preview: leave it and it's gone from your sessions.
• Better battery life while sharing your position, plus stability fixes.
