Frequently asked questions

Answers to what people ask the most.

Does the app work offline?

Yes — once you connect once, maps and the latest positions are cached locally. When you lose signal you still see the last known teammate positions, and chat messages are queued for delivery when the connection is restored.

What is the battery consumption?

The biggest battery drain is high-accuracy GPS. Thanks to the adaptive GPS interval based on player activity, consumption is typically around 10–15 % of the battery for ~2 hours of active tracking. Battery health also matters. When the phone sits still, the GPS sampling interval extends, saving battery.

What if I lose signal mid-event?

The app keeps tracking GPS locally, queues positions, and once the connection is restored it syncs everything. Maps remain available from local cache. Push notifications arrive with a delay once you reconnect.

How do I protect myself if captured?

Use Lock mode — tap the map five times and the app switches to a decoy snapshot. Once active, the enemy sees a screen that looks like a normal map, but with shuffled positions. Long-press on “Tools” unlocks and returns you to the game.

What platforms can I play on?

STORM has native iOS and Android apps. The app can also be used in a regular web browser on PC, tablet, or mobile, but with limited features. A web browser cannot send GPS position when in the background, and you won't receive any notifications. Web browser usage requires the device to be unlocked and the browser kept in the foreground. It's more of a viewer of what is happening. You can still create markers, draw on the map, etc. — most features are available in the web browser too.

Do you collect my data?

Only what is necessary — callsign, GPS positions, chat, mission photos. Used solely for the event, on our server in the EU. No ads, no third-party analytics. Details in the privacy policy.

How long do you keep data?

For the duration of the event + 12 months for replay and statistics. After 12 months the event is archived and personal data (callsigns, IP) is anonymized. You can request deletion any time.

Can I upload my own map?

Yes, the event organizer can upload a game overlay as a TMS ZIP. The map renders over an OSM base with adjustable opacity. If OSM doesn't suit you, you can use a different base map and put the game layer on top of that.

How many players can an event handle?

The server is tested for ~100 players per faction (so ~200 in total). The bottleneck is more on the mobile-device side. Many markers/players in a small area can overwhelm mobile rendering — you need to use filters and only show what is necessary on the map. Larger events are possible but require server tuning. For those, contact us.

How do I report a bug or suggest a feature?

Use the form in the Feedback section — you'll find both bug reports and feature suggestions there. For new features, describe the use case from a real game situation — it really helps when designing the solution. For bugs, include platform, app version, and steps to reproduce.

Is STORM open-source?

Not at the moment. STORM is still being developed and stabilized, and serves the internal needs of Metrocity Squad and partners. If you're interested in deploying it on your own servers, we plan to support that in the future.

Does mesh radio (LoRa) work?

Yes, we support a Meshtastic gateway over MQTT. Mesh players (with a LoRa device like the Heltec T114) are full event participants — chat, GPS positions, marker creation, bidirectional via LoRa into the main map. For now this feature is being tested on Android only and isn't fully working yet.

Who pays for STORM? How come it's free?

Nobody. The idea was born out of the absence of a solution like this. The only paid part is the App Store release, which the airsoft community chipped in for. The goal is high-quality mil-sim events, and that needs feedback from you — the players. Let's make our game fun, and as long as I have the strength, drive and energy, I'll happily keep pushing STORM forward for free.

What's the goal of STORM? Is it trying to compete with something?

Not at all. It was an idea that came overnight. I enjoy airsoft and mil-sim events, and my goal is to build — together with you — an app that serves all of us.
