When Apple introduced 3D Touch for the iPhone 6s in 2015, it seemed like a gimmick. But with iOS 10 and the iPhone 7, it became much more useful, thanks in large part to Home screen quick actions, which are handy shortcuts you access via 3D Touch on any Home screen app icon. For instance, press and hold on the Reminders app to view (and check off!) scheduled reminders plus add new ones quickly. Photos gives you single-tap access to a few of Apple’s automatically generated Memories, along with other photo collections and searching. And Music makes it easy to start playing recent albums and playlists, search for music, and tune into Apple’s Beats 1 radio station.
