The first Android app built specifically for buggy convoys. Group sync, hazard alerts, photos, music — all in one.
Locus, GAIA, OruxMaps are great — for solo riding. When there are 8 buggies of you in the Rhodopes and one breaks down 5km behind you, you need a different tool.
See every buggy in the group on the map in real time. 3-digit code to join. Firebase sync.
One tap → triangle alert + TTS notification + flash on every device in the group. "Careful, pothole."
Shoot with the camera → share to Hellstorm → it's automatically attached to the current adventure. Late-join EXIF match.
The leader plays a track — every buggy plays it in sync (±100ms drift). Server-time scheduling.
Satellite (ESRI, Google), topo (OpenTopoMap, ESRI Topo, OSM), humanitarian. Switch with one tap.
Every convoy is saved as an "adventure" — track + waypoints + photos in one frozen memory view forever.
Long-press on the map → drop a POI (water, repair, camp). Synced with the group. Personal POI library at the end.
Red button → SOS marker for everyone in the group. Voice announcement via TTS. Visible on your own device.
Snapshot every 10 seconds. Samsung battery saver kills it? Recording resumes exactly from the interruption on restart.
A real full-day adventure on 2026-05-09. 3 buggies, GPX data, 7 photos, 2 waypoints.

Hellstorm Track collects only your GPS position (for recording + group sync) and photos (when you share them explicitly). No analytics, no advertising trackers. The data lives in Firebase (Google EU multi-region) and is accessible only to members of the group.
