A shared map for one airsoft team, and for the events they run.
Everyone on your team opens the same map and sees where the others are, live, on satellite imagery. You can drop markers for enemy contacts, vehicles and bases, draw on the map to sketch a plan, and run a shared clock so the whole field agrees what time it is.
It is a web app. There is nothing to install from an app store — you open a link, and you can add it to your home screen if you want it to behave like an app.
A bigger game can run as an event: two teams in one world, with a host who can see both. You join with the event key, wait in a lobby where you can see nothing, and the host puts you on a team. From then on you see your own team and never the other one — that separation is enforced by the server, not just hidden in the app.
Events can run over several days, standing down at night and starting again in the morning, and they carry a scoreboard both teams can see and a boundary marking the edge of the field.
It never hides you from your own team. The map is at its most valuable for the person who is 200 m outside the line and not answering their radio. Nothing in it is allowed to be the reason a hurt or lost teammate is invisible.
It is allowed to be late. It is never allowed to lie. An old position goes grey and tells you how old it is. It never quietly becomes a confident dot in the wrong place, and it never becomes nothing at all.
You can stop sharing, and it says so when you do. Press HIT and your position freezes where you were, flagged, so your walk back to respawn is not broadcast. At an event, standing down for the night stops your phone transmitting entirely. Both are announced on your own screen — neither is a silent disappearance.
It is a private hobby project, run by the person who gave you the key, on a small server they pay for. It is not a company and not a commercial service.
It records where you are. That is the whole point of it, and it is worth understanding properly before you use it. The Terms of Use set out exactly what is recorded, who can see it, and how long it is kept.
There is an age rule. Nobody under 13, and under 18s only with a parent or guardian who knows what it shares. Whoever hands out the key has to apply that — the app cannot.
