I discovered today that the iOS app has interval sounds when I happened to have my ringer switch on (it’s usually on mute).
I’d much prefer it if the interval sounds were actual app sounds with in-app control rather than phone notifications, then it’s not dependent on the ringer switch.
Also on the topic of interval sounds - not sure if this is planned or in beta, but it would be good if the remote player had interval sounds too, that way if you have headphones connected to the device with the remote player you could hear the sounds.
