CargoTrak is a hybrid mobile app developed using Telerik that allows users to track jobs, check reports, and receive alerts about job status from their mobile devices. It provides a mobile version of an existing web platform called Polaris Explorer. As a hybrid app, it can be deployed across iOS, Android, and Windows devices using a single codebase, making it more cost-effective and efficient to develop and maintain than creating native apps for each platform separately. Some current limitations of the hybrid approach include limitations on the number of data columns that can be displayed and device requirements like an internet connection to function fully.
