DirtOS vs Field Sentinel Mapper

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. - Offline tracking via Meshtastic LoRa — share location with zero cell service. T1000-E, Wio Tracker, Heltec supported. - Public + private + persistent multi-day groups. RACE ORGANIZER PORTAL NEW: dirtos.io/org — web console for race directors. Import a master route, broadcast text or voice to every registered racer. All updates land instantly in the app. TRAIL FINDER + CUSTOM ROUTING - Trail Finder — drop pins on satellite imagery, DirtOS traces unmapped desert roads between them. - Custom GraphHopper routing, 116M edges, 9 vehicle profiles from dirt bike to full-size 4x4. - Universal Go To — tap any address, POI, coordinate, or group member. - Automatic gas stop insertion based on fuel range you set. Section Delete + Connect for field edits. OFFLINE MAPS - Route Corridor Download follows your actual track shape — 5-10x fewer tiles than a bounding box. - Silent Zoom Clamp so the map never goes white when cell drops. - Zombie-Cell Detection falls back to your downloaded zoom automatically when tiles start failing. - Region Download with polygon selection. Storage Manager with per-region size + zoom range. TOUR MODE + WEATHER - Tour Mode — Wikipedia landmarks narrated as you drive. - NEXRAD radar overlay + NWS forecast + severe alerts + precipitation warnings 20 miles ahead. ROUTE MANAGEMENT - Merge Items combines routes, tracks, or runs. - Record Mode, 3D Flyover Preview, Photo Waypoints Overlay, Cloud Sync. - USFS + BLM Trail Overlay filtered by vehicle type. RACING ESSENTIALS Next 3 Waypoints Display, Compass Pointer, Off-Course Warnings, Speed Zones with over-speed alerts, Chase Cam (double-tap Find Me for heading-up view) 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.
