The ability to customize alert tones for applications on Apple’s mobile operating system allows for differentiation between various incoming notifications. This functionality provides users a way to audibly distinguish an Instagram notification from those originating from other applications installed on their iPhone.
This capability improves user experience by enabling rapid identification of notification sources without requiring visual inspection of the device. Historically, customizing application-specific notification sounds on iOS devices has been limited, requiring workarounds or the utilization of system-wide sound alterations which affected all notifications.
