Hammer review

Hammer is the free option on this list, built by the TruckersReport.com community. The App Store listing describes turn-by-turn directions customized for commercial vehicles, with routing that considers a truck's height, weight, length, axle count and cargo type. Maps work offline, the app reroutes around traffic, accidents and closures, and multi-stop route optimization with custom waypoints is included. Drivers also get weigh station alerts, speed limit notifications, lane guidance and POIs for fuel, truck stops, rest areas and parking with diesel prices. Coverage spans the United States including Alaska and Hawaii, Canada and Mexico. Hammer is free to download with in-app purchases, and the vendor site does not publish what each paid tier adds, so check the store before relying on any extra. It has no dispatcher portal, which makes it a driver tool rather than a fleet system.
