Listening to music on our iPhones is one of the most classic uses for the device. The Music app has been with us since the beginning, in the form of the old iPod app. It has gone through a few iterations and improvements throughout the years, but there is always something that third-party apps are doing differently or better.
Feedback, by Ron Thakrar (@ronthakrar) enables audio and haptic feedback for media controls. It only works when controlling audio playback remotely, like in the Control Center or Lock screen. For example, it doesn't work within an app itself, when you're in the Music app and press play or skip track it won't make any feedback sounds.
