The professional sound app allows the user to see the sound level meter data from the MONICA system. It also provides functionality to give sound feedback to the COP indicating sound problems at certain place.
The app is developed in Swift using Apple XCode and is a pure iOS app. Clone the repository and build the app in Apple XCode. The default endpoint it contacts the COP APi is http://127.0.0.1:8800/ Which matches the port in Sound Monitoring an event using Sound Level Meters
If another adress and port is to be used, locate the file "MonicaPro\AsyncTask.swift" and change:
private static let baseStart = "http://127.0.0.1:8800/"
Change it to desired adress and port and rebuild.
