"Repertoire" is a small app that allows choir and ensemble directors, solo artists (or other interested parties) to keep their repertoire alive. It records the pieces sung/played and prac- ticed for events (rehearsals, performances), making it possible to track when a piece was last sung or played. That is the entire goal of this app. Repertoire makes it possible to manage multiple choirs/ensembles, each of which wishes to maintain its own repertoire. Depending on the system settings, this data can also be syn- chronized between multiple devices using a common Apple ID via iCloud.
