# What is App‑to‑App communication?

Organizations often use work order management systems to dispatch work to front-line workers by means of a mobile app. The work orders typically provide essential information about scheduling, work location, customer contacts, and details of the service to be delivered.
App‑to‑App communication provides a way for the work order management system to transfer these “top-level” details to the TrueContext Mobile App, so that front-line workers benefit from the in-depth, dynamic workflow that the TrueContext Mobile App provides.
App‑to‑App communication works even when a user’s device is offline. This is critical for managing workflows in which the source app requires confirmation from the TrueContext Mobile App that a step was completed before the user can proceed with the next step.
