LeadNav GPS vs DirtOS

LEADNAV GPS is the professional off-road GPS for iPhone and iPad. Plan the route at home, run it with turn-by-turn voice guidance where there are no roads, and put your whole team on one map. Built for teams that work and travel off the grid: search and rescue, security details, expeditions, hunting camps, work crews, race teams and their chase crews. NAVIGATE WHERE THERE ARE NO ROADS • Turn-by-turn voice guidance from routes you build or import. Waypoints speak by name as you approach them. • Red warning rings and blue proximity rings that adjust to your speed, so the call comes when you need it. • Any ring you cross alerts, on the route or off it. Serpentine points keep you on the line without a word. • Works with no signal at all. Navigation never needs a connection. • Record tracks, convert them to routes, reverse a route to come back the way you went. • Drop markers for anything you want to find again. Recon, Aviation and Hunting marker sets are included for everyone. • Compatible with Bluetooth headsets, helmet intercoms and speakers for eyes-free navigation. TRIP PACKAGES • One file per trip, event or property: routes, tracks and markers together, with categories and Recently Deleted. • Built on the GPX standard. Import from and export to any GPS device or planning software. • Share a whole Trip Package with your team by AirDrop, Messages or email. • Route Editor with Undo, Join Multiple Routes, Convert Markers to Audio Waypoints, Export to GPS Unit for Garmin, Lowrance and other units. YOUR WHOLE TEAM ON ONE MAP • Group tracking is included with the app. One Team Code, a QR or an invite link builds the team. Teammates join in seconds and see each other live. • Runs over any internet connection: cellular, Wi-Fi at camp, or vehicle-mounted satellite internet such as Starlink. • Keeps sharing with the screen locked when you turn on background tracking. • No account, no login, nothing to sign up for. Your team identity is a random code you can reset any time. COMMS (PRO LICENSE) • Hold to talk with your teams from the pad on the map or from a wireless button. Release to send. • Every message is written out as text in the team thread, so a call you missed at speed is still there when you look down. • Several teams at once, each with its own channel and switch. Faster updates, teammate speed, off-screen arrows and breadcrumb trails. PRERUNNING TOOLS (PRO LICENSE) • PreRunner Bar and Pocket PreRunner: one-tap waypoint drops at speed, with a wipe-safe screen lock. • Wireless buttons: drop waypoints, record tracks, zoom and talk with your hands on the wheel. Part of our patent-pending prerunning system. • Waypoint Mic: hands-free voice notes at speed through your helmet comms. • Speed Highlighter: paint the route green, yellow and red as you run it. • Package Rules: proximity rings and marker symbols by name, saved in the file for everyone you share it with. • Off Route Alert: hear it the moment you leave the line, and which side the route is on. • Edit at speed: tap any waypoint in run mode to edit or delete it. OFFLINE MAPS • Free online map sources include USGS Satellite, USGS Topo and OpenStreetMap. • The Entry and Pro Licenses add offline map imagery for every map type, MBTiles import and overlays, and custom map URLs. Select areas and store them before you go. Maps are provided by outside services and are subject to change. LICENSES The app is a one-time purchase. Entry and Pro are auto-renewing licenses, managed in your Apple account. Details at leadnavgps.com/pricing. NOTES • This is a high-powered GPS and needs power for prolonged use in the field. Continued background GPS use can dramatically decrease battery life. • Wi-Fi-only iPads have no internal GPS chip. Use a cellular model, or an external GPS receiver with the app. • Group tracking and Comms need an internet connection. Navigation does not.
