What's New in DirtOS
4.3.6
November 1, 2026
Voice keywords for your Bluetooth button, a full-screen flyover, a clearer map, pacenote-style callouts, and the whole DirtOS guide in your pocket. **Voice keywords** Settings → Bluetooth Button pairs your push-to-talk button and holds your voice keywords. Hold the button, say "Danger, big rock", and the waypoint drops with the Danger icon and colour — named with everything you said. Triple Danger, Double Danger, Danger and Go are set up for you; add your own and pick each one's icon and colour. **Flyover** Pause a flyover to change its speed and zoom — pinch or tap + and −. The controls slide away while it plays so the map fills the screen, and a dot shows where you are on the route. **Feature Guide built in** Settings → Need Help? now opens the full DirtOS guide — searchable, and it works offline. **Pacenote-style distance to the next turn** Turn on Settings → Turn Detection → Announce Distance to Next Turn and hear it like a co-driver: "Right 2, 150". **Clearer waypoints** Waypoint names sit in a crisp black box with white letters, dot colors match the turn severity, and names step back when you're not on a Run so the map stays readable. **Smoother location arrow** Your arrow and range rings glide between GPS fixes and point the way you're facing. **Collections** New "Only routes on the map" filter in the Sort menu, a count of what's showing in each collection, and full item names. **Run** Open Settings without stopping your Run. Starting a Run offers to hide the other routes on the map for that run. Distance to finish now counts down on routes with no waypoints. **Group Ride** Make group member dots and names bigger or smaller.
