- A song is defined as an unbroken run of at least five syllables; chatter is separated.
Field notes
The app is described as having six sound groups, with tracks available for download and playback when the screen is off. Its video counter uses a threshold of five continuous syllables for a song, records the syllable count and the gap before the next song, and treats chatter separately. The site also describes a sleep timer, track search, and playback controls on the lock screen, notifications, and a home-screen widget.
