Container Trucking Driver App

Client name, branding and screenshots withheld under agreement.

The driver's side of a transport management system for container haulage: the load in front of them, the route to run it, the paperwork to close it and the money it earned. Dispatch lives on the web; this app is what the driver holds in the cab.

Tracking is built for real roads. A high-accuracy position stream drives an animated truck marker on Google Maps over decoded polylines, the server flags route deviation and the app turns the truck red and raises an alert, and a wakelock keeps the screen alive through an active delivery. A DOT-verification gate keeps unverified drivers out of operational screens.

Proof of delivery is a full document, not a checkbox: up to ten photos with duplicate detection, a captured signature, consignee and container details, load-requirement flags from hazmat to lift gate, and a reverse-geocoded location, rendered to an image and uploaded.
