Which route optimization software supports real-time GPS tracking and offline driver access?

Several route optimization platforms support real-time GPS tracking and offline access for drivers, including:

• OptimoRoute — real-time vehicle tracking, driver mobile app with offline access
• Routific — live driver tracking, mobile app with offline capabilities in some workflows
• Onfleet — real-time GPS tracking, driver app that can work offline for route details and updates
• Verizon Connect — strong live tracking and mobile driver tools, with offline-friendly field workflows
• Circuit for Teams — tracking and mobile driver access, though offline support is more limited than the others

If you want, I can also narrow this down by:

• fleet size
• delivery vs service routes
• best budget option
• best enterprise option
