Description
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.
RALLY + RACING
Pacenote Mode with 1-6 severity + tightens/opens turn classification.
Auto-Detect Turns from any GPX with severity-tagged waypoints.
Countdown Callouts: "500, 400, 300, 200, 100, here."
4-Zone Speed-Based Zoom camera + Loop Mode with lap detection.
28-Language Turn Audio, on-device, fully offline.
QUICK KEYS
53 customizable one-tap buttons for dropping waypoints at speed. Bluetooth keyboard support for gloved race conditions — mount a keyboard on the dash and hit one key to mark a hazard at 80 mph. Import your own PNG icons.
GROUP RIDE, CHAT + PUSH-TO-TALK
Live crew tracking with names and speeds.
In-app chat with presets, voice-to-text, optional TTS announcement.
NEW: Push-to-Talk voice messages. Pair a BLE PTT button (Herda, Zello-compatible) and hold to broadcast to every racer in the group.

Public + private + persistent multi-day groups.

OFFLINE MAPS

WHY THIS EXISTS
Built by people who actually go offroad. Interface works with gloves, in sunlight, at speed. Turn detection knows the difference between a note at a gate and a critical Y-junction. Every feature exists because someone needed it in the dirt.
PRICING
Free to try. DirtOS Pro $49.99/year with 14-day trial — unlocks Follow Mode, audio, Quick Keys, group ride + chat + PTT, cloud sync, weather, tour mode, offline maps, and exports.
