As with 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 not accept a call, or calculating fitness activities, including your 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 — like counting the steps you climb or descend — as well as calculating altitude, for those who ski, hike, or mountain climb!

Beginning with Apple Watch Series 6, it’s now an “always-on” altimeter for all-day real-time elevation data captured on your wrist.

With the Apple Watch’s accelerometer and gyroscope sensor, Apple Watch Series 4 (2018), Apple Watch Series 5 (2019), Apple Watch Series 6 (2020), and Apple Watch SE (2020) all can detect if 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.

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