Apple seems to be starting to realize how important additional physical buttons are on a smartphone and how wonderful it would be if users could do various customizations. In the iOS 18.4 update that has been distributed to developers, Apple has included 4 new options to launch by simply pressing the Action Button.
This feature is called Ambient Music for users to play music that enlivens the quiet atmosphere. Apple has included 4 different modes, namely Chill, Productivity, Sleep and Wellbeing. Each of these modes actually only launches a music playlist on Apple Music that Apple has set. For example, the playlists offered are BEATstrumentals, Binaural Frequencies, Pure Focus and Classical Concentration.
Apple also allows users to quickly access these playlists via the lock screen. At the moment, the motive for this feature is still unclear, because accessing Apple Music has always been easy and fast. Apple may want users to use their Journal app more often, by writing while listening to calm music.
