A smartwatch is designed to make your life easier and get you off your phone. Every time you have to dig your phone out of your pocket to read a notification, a digital fairy dies. However, a smartwatch is also less useful if you have to drop whatever you're doing to squint and poke your finger at a tiny screen. In October, Apple debuted Double Tap in WatchOS 10.1. If you own a Series 9 or a Watch Ultra 2, you can now quickly tap the index and thumb of your watch hand to perform the primary action on your watch.

Apple added a new gesture to the Apple Watch Series 9 and Apple Watch Ultra 2 that the company believes will change how you use your wearable. Double Tap lets you control various system functions by tapping your thumb and index finger together twice in quick succession -- no need to touch the display or free up your other hand. The company gave several examples of the feature in action. You can use Double Tap to answer or end calls, snooze alarms, play / pause music or start and stop timers. Apple COO Jeff Williams said it's especially useful for times when your other hand isn't free, like when walking a dog or carrying groceries.
