DirtOS vs DirtSync

DirtOS is GPS built specifically for off-road — racers, chasers, rally teams, overlanders, UTV crews etc. Not a generic outdoor app with a "trail mode" tacked on. Built by people who actually drive in the dirt.

TOUR MODE + WEATHER - Tour Mode — Wikipedia landmarks narrated as you drive. - NEXRAD radar overlay + NWS forecast + severe alerts + precipitation warnings 20 miles ahead.

DirtSync keeps your whole group on the map — even when cell service is gone. Built for off-road crews, trail parks, guided rides, and anyone who has ever turned around to go find somebody. Create a session, share a 7-character code, and every rider appears on a live satellite map in under 60 seconds. No account required. WORKS WHERE OTHER APPS STOP DirtSync uses your internet connection when it's available and automatically switches to mesh radio when the trail goes dark. Connect a Meshtastic LoRa node over Bluetooth and your position, chat messages, and SOS alerts keep moving over radio — canyon, timber, deep park, no signal — it doesn't matter. LIVE RIDER TRACKING Every rider on the map with name, speed, heading, and live status. See who's ahead, who's behind, and who hasn't moved in a while. ONE-TAP SOS Send an SOS with your exact GPS coordinates to every rider and Mission Control instantly. Works over mesh radio when there's no cell signal — so help knows where to go even in a dead zone. TRAIL MAPS Import KML, KMZ, and GPX files from Google Earth, Gaia GPS, or CalTopo. Trail names and colors are preserved and shared to every rider in the session the moment you upload. RIDE CHAT Group chat that routes through the cloud when you have signal and through mesh radio when you don't. Messages find a path either way. WAYPOINTS Drop hazards, water crossings, fuel stops, and photo spots on the map. Visible to every rider instantly. MISSION CONTROL Park operators, ride leaders, and guides get a full web dashboard — live riders, SOS alerts, chat, trail maps, waypoints, and draw tools from any browser. No app install required for the operator. GPX EXPORT Export your recorded ride track as a GPX file for mapping, analysis, or sharing after the ride. SESSION CODES 7-character codes like DUST421 or RIDE873 — short enough to fit a Baofeng channel name. Share it at the trailhead and everyone is on the map before the first rider rolls out. Free for riders. No account required. For park licensing, relay station installs, and Node Kit fleet pricing — contact us at jdmatkowski@gmail.com.
