Siri

Instead of coming with physical volume controls like Apple's EarPods, Apple's AirPods includes a "double tap" feature that invokes Siri for users to play music, skip tracks and answer calls. Anyone who has used Siri knows that the voice assitant can sometimes be unreliable, and this is why you'll probably want to reprogram your AirPods once they're setup.

Apple's Shortcuts app offers hundreds of pre-written algorithms designed to accomplish tasks that would normally take many steps in just one or a few steps. For example, the Home ETA shortcut uses Maps and Messages to find your location, find a route home, estimate the time that route takes and text that time to whoever you set up the shortcut to send it to, all with a single tap.

Siri enjoys delivering answers to iPhone owners whether their devices are locked or unlocked. Sometimes the call "Hey Siri" is even answered no matter who is asking. Pressing the Side button or Home button can also invoke Siri from the Lock Screen. For those who consider this a privacy or security risk, Siri can be completely disabled when the iPhone is locked.
