Sound Tools comes with a real Apple Watch app, not a remote control: tune and keep time from your wrist, even with your iPhone left at home.
In a rehearsal with drums and amps, a speaker click gets lost. The watch metronome taps the beat on your wrist with haptics, so it is still there when the sound is not. Your setlist comes along too, to move from song to song without reaching for your phone.
The watch listens through its own microphone and shows the note and the cents, with the same detection as the iPhone app. Handy for touching up a string between songs.
