Functions

Apple Watch Series 5: fall detection and compass

Unlike he Apple Watch Series 3, the Apple Watch Series 5 has fall detection and a compass. Should you fall hard, the Apple Watch will detect this. You get a tap on the wrist, an alarm sounds from your Apple Watch, and it displays a warning on the screen. If you fell down but didn't sustain any damage, you can tap on 'I'm OK'. If you don't respond for an entire minute, the Apple Watch automatically rings the emergency services. Thanks to the integrated compass of the Apple Watch Series 5, you'll never lose your way again.

Apple Watch Series 3 altimeter

Apple Watch Series 3: altimeter

Just like on the Apple Watch Series 5, you'll find a barometric altimeter on the Apple Watch Series 3. This allows you to measure the number of stairs you climb during the day, for example. You don't need to carry your Apple iPhone in your pocket for that. And if you go for a run outdoors and find yourself running uphill, the Apple Watch measures this as well thanks to the altimeter.

Your watch uses about 3GB of the total 32GB of storage for the operating system watchOS, but this means you have plenty of storage space left to store your favorite music, photos, and apps on the Apple Watch.

Choose an Apple Watch with more storage capacity than 8GB.

Conclusion

The new functions of the Apple Watch Series 5 make it worth my while to upgrade from the Apple Watch Series 3 to the Apple Watch Series 5. The always-on screen ensures I always know exactly what time it is, just like with an analog watch. The ECG function constantly monitors my heart rate and fall detection alerts emergency services in case I should fall. This makes me feel safe. On top of that, I can store a lot more music, photos, and apps on the Apple Watch Series 5 than on the Apple Watch Series 3 thanks to the larger storage capacity. In short, Apple Watch Series 5 is a real improvement.
