Zum is a free iPhone app developed by Zum Services Inc. It aims to provide flexible, efficient, connected, and sustainable student transportation to school districts, communities, and families across the United States. With Zum, parents can easily track and manage their child's school rides.

The app offers several features to make the transportation process convenient for parents. They can quickly view driver and vehicle profiles, track the location of vehicles and their child's ride progression in real-time, and receive pickup and dropoff notifications. Parents can also provide specific instructions for their child's driver and leave feedback about the driver or their child's experience on the ride. Additionally, the app allows parents to easily communicate changes or cancel a ride if their child is sick or absent.

Zum ensures the quality of their drivers through a rigorous selection and vetting process. The app provides full transparency, aiming to eliminate the chaos and anxiety of getting students to and from school every day.
