Although the Apple Watch Series 5 introduced fall detection and an updated heart sensor, the Series 3 can still meet most of your health needs.
With the Apple Watch Series 3, you can track your activity each day, see how many calories you've burned, and use smart coaching for an extra push in workouts.
You can track your stats on different types of workouts, too: yoga, cycling, running, interval training, and more.

The Series 3 can also warn you about unusually high or low heart rates, and screen for an irregular heart rhythm indicative of other health problems. When one of these issues is detected, you can call for help through Emergency SOS on the watch.
