Gryvn Zthru runs entirely on your iOS device without requiring external servers or GPS tracking subscriptions. The dispatch engine evaluates every pending order against your active trips locally, checking cargo weight against remaining capacity, calculating detour distances from planned routes, and verifying delivery time windows downstream. This on-device processing means your fleet data stays private and the system continues working even when cell service drops.
Fleet coordinators log truck departures and arrivals manually, creating a calculated position system that updates each vehicle location based on route distance and elapsed time. The app maintains a city-distance library you build yourself, allowing accurate ETA calculations without internet lookups. When evaluating backhaul candidates, the ranking algorithm considers deadhead mileage to pickup, maximum acceptable detour from original route, and whether adding the order would create downstream capacity conflicts or time window violations.
The Fleet Overview aggregates data across all registered trucks to show total utilization percentage, count vehicles currently on route versus idle, and flag trips where calculated arrival times exceed delivery windows. Risk alerts identify drivers approaching hours-of-service limits and routes with capacity conflicts. Because everything processes locally, coordinators can work in truck yards, warehouses, or anywhere without depending on network connectivity. The app never requires account creation, keeping your operation independent and your fleet information secure on your device.
