The Score Stack is an iPhone application designed for music enthusiasts looking to streamline their music and audio organization. This app allows users to create groups for different musical ensembles, providing a platform to store sheet music, practice tracks, and other rehearsal essentials. Users can upload sheet music with all required part tracks, which can be edited or deleted as needed.

Moreover, The Score Stack enables group creators to add members with varying levels of access, such as "Member," "Co-Owner," or "Owner." Members can view content, Co-Owners can add, edit, delete documents and audio files, and manage group members, while Owners have full control over group management, including editing, deleting documents, adding or removing members.
