Apple recently released watchOS 10.1, with support for the much-ballyhooed double-tap gesture that selects the primary action in many apps without requiring that you touch the screen! It’s available only on the new Apple Watch Series 9 and Apple Watch Ultra 2, where you activate it by raising your wrist and tapping your thumb and index finger together twice. On the main Apple Watch screen, a double tap opens the Smart Stack of widgets you would otherwise get by turning the Digital Crown, and subsequent double taps advance through the widgets. A double tap also activates the primary action in many apps, such as answering and ending phone calls, playing and pausing media, viewing and scrolling through messages, ending timers, stopping and resuming the stopwatch, snoozing an alarm, responding to reminders from the Workout app, and performing the primary action from notifications. Whenever you double tap, you’ll see this icon 
at the top of the screen. If you have a supported Apple Watch model, give it a try!
