Like other smartwatches and activity bands on the market, Apple Watch has an accelerometer that measures movement, whether you’re lifting the watch to your face to turn on the screen; lowering your wrist to decline a call; or calculating fitness activities, including steps taken (like a 21st-century pedometer), total distance traveled, time spent exercising, and estimated calories burned. Beginning with Apple Watch Series 3 (2017), the watch also has an integrated barometric altimeter for measuring elevation (counting the steps you climb or descend) as well as calculating altitude for those who ski, hike, or climb mountains. Beginning with Apple Watch Series 6, the altimeter is always on, providing all-day, real-time elevation data on your wrist.

With the Apple Watch’s accelerometer and gyroscope sensor, Apple Watch Series 4 (2018) and newer models can detect whether you’ve fallen, and you can initiate a call to emergency services (or dismiss the alert). If you’re unresponsive after 60 seconds, Apple Watch automatically places the emergency call and sends a message with your location to your emergency contacts. Note: This feature is different from speaking to a live operator if you call, as you would with a service such as Philips Lifeline, but this feature is very handy to have on your wrist nonetheless (and you have no monthly fees to worry about).

A compass has been added to Apple Watch Series 5 and Series 6 models, always pointing you north inside apps like Maps, and there’s a dedicated Compass app too. (Cue the song “Go West” by the Pet Shop Boys or the Village People first!)
