ohaco: The Offline Songbook for Karaoke and Buskers

Field notes

ohaco organizes repertoire around performance situations rather than simple playlists. Its described records include best keys, capo positions from 1–7, BPM, scores, practice timelines, and bottleneck tags such as high notes or barre chords. The page also describes separate vocal and guitar layouts, setlist reordering, and local storage through an Isar database. Apple Music lookup and ShazamKit recognition are presented as song-entry features, while external chord pages remain part of the workflow.
