The Mobile App Simulator is a free, open-source project built for and partially funded by the HL7 Da Vinci Project. The application is a reference implementation that demonstrates the CMS Interoperability Final Rule Patient API use case. It’s a web app that simulates a mobile phone and connects to any publicly accessible Patient API endpoint. It can be used by both technical and non-technical users to verify the operation of a Patient API, test the security, and verify the field level output.

The app consists of two parts; the mobile screen emulation on the left side, and the configuration and debug information on the right side.

The following functions are supported:

​

• Demonstrates entire SMART on FHIR and OAUTH2.0 functionality

• Executes read operations against a target server using everything or individual FHIR resource functions

• Enables configuration of one or more FHIR servers and validation of their IPs connection details

• Enables view of data sources separately or as combined resources

• Displays returned output as both a mobile phone UI and as raw JSON

• Allows filtering and sorting, multiple or single source FHIR data on mobile UI

• Allows returned datasets to be searched, filtered, and copied

• Connects against authenticated and non-authenticated server endpoints
