Field notes
Groups build their own repertoire rather than receiving a supplied song catalog, then arrange songs into service sections such as Alabanza or Ministración. The sample set includes singer assignments and notes when a song was recently used. The page also describes a tuner that gives spoken direction and says its microphone is active only while that tab is open; internet synchronization is optional, with group sharing handled by code.
