Oracle Field Service Mobile is a business and productivity app developed by Oracle America Inc. The app allows mobile workers to easily access, execute, and manage work-related activities and ongoing communications from their iPhone. With this app, users can retrieve activities, manage routes, view activity details, provide activity updates, manage inventory, and communicate with peers.

One of the key features of Oracle Field Service Mobile is its ability to work offline. Mobile workers can use the app even without internet connectivity, and any actions taken while offline will automatically synchronize when connectivity is established. This ensures that users can continue their work seamlessly, regardless of their network status.

Furthermore, when used in conjunction with Oracle Field Service Smart Location, the app extends its functionality to continually gather a mobile worker's coordinates even when running in the background. This can be particularly useful for tracking and monitoring purposes.

Please note that Oracle Field Service Mobile requires an active Oracle Field Service subscription, and the available features may vary depending on the subscription services.
