What's New in DirtOS

4.3.1

August 28, 2026

Know the land. Ride it in any language, any orientation. Land Ownership overlay See who owns the land, nationwide: BLM, Forest Service, National Parks, state trust land, and more — color-coded over the satellite map, with private land left clear. Tap any parcel for the agency and unit name. Turn it on in Settings → Map Overlays. Landscape mode Rotate sideways for dash mounts and wide screens: the next-3 waypoint panel moves to the left edge and the whole navigation display rearranges to use the space. Speed zone limit sign When you enter a speed-restricted zone, the limit now shows as a sign on screen — and turns red if you're over it. Callouts in your language Turn callouts now use your phone's built-in translator (iOS 18+) so waypoints are spoken natively in Spanish and 27 other languages — even when the course was marked in English. The app tells you if a language pack needs downloading instead of failing silently. Smarter callouts Close-together waypoints chain into a single call — "Ruts in 150 feet, then Danger" — and a new Short Numbers option reads distances digit by digit ("two nine zero") for radio-style clarity. Submit your trails Found or recorded a great trail? Submit it to DirtOS right from the item menu — name it, rate the difficulty, tag the biggest vehicle that fits — and help grow the trail map for everyone. Race ops direct messages Race organizers can now message individual riders privately from the portal, alongside the existing group broadcasts.
