QueUp is an iPhone application developed by Louis Menacho, offering a unique way for friends to create collaborative music playlists. Users can host a room where everyone can add their favorite songs, fostering a shared music experience. By linking Spotify accounts and connecting the host device to a speaker, QueUp enhances group music listening sessions.

With QueUp, users can host a room to initiate a collaborative playlist, invite friends to contribute songs, and sync the playlist to a Spotify account for easy access. Additionally, the app allows users to search Spotify's extensive music catalog and enjoy synchronized music playback through the host's device.
