Server version of Hymnbook for Organists. With this app, organists can enter the singing number, verse, and psalm that are automatically set up for all worshipers who are connected to the same Wi-Fi network.
For proper functioning it is necessary to have a separate server in the parish (Raspberry PI). Every organist must have his / her code set in the application, otherwise he / she will not be able to set anything for the worship service.
The new version of the application supports control of multiple organists at the same time.
