Heart rate measurement
Apple Watch Series 5: electrical heart rate sensor
The Apple Watch Series 5 introduces a new Apple Watch function, the ECG. With the ECG app, you can make a recording of your heart's activity, also known as an electrocardiogram. The ECG app gives you a notification when your have an irregular cardiac rhythm. As such, the ECG function makes it easier to detect atrial fibrillation, which is the most common type of heart arrhythmia. In addition to the electrical heart rate sensor, the Apple Watch Series 5 also has an optical heart rate sensor of the second generation.
Apple Watch Series 3: optical heart rate sensor
The Apple Watch Series 3 only has a first-generation optical heart rate sensor. With green LED lights on the back of the watch case, the Apple Watch measures how much blood flows through your veins. The optical heart rate sensor supports a range of 30 to 210 heartbeats per minute. The optical heart rate sensor is constantly active, so you have insight into your heart rate all day long. Thanks to the optical heart rate sensor, you also have insight into your heart rate during exercise.
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
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.
Apple Watch Series 5: 32GB
Another big plus of the Apple Watch Series 5 is the storage capacity. The fifth-generation watch has no less than 32GB of storage. You can use this to store music or podcasts on your Apple Watch. 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.
Apple Watch Series 3: 8GB
With the third-generation model of the Apple Watch, you get 8GB of storage capacity. This model also uses about 3GB for the operating system. You're left with 5GB to store your photos and music. If you store music on the Apple Watch, you can also listen to your favorite band when your iPhone isn't around. Do you have long playlists that you like to listen to during exercise, for example? Choose an Apple Watch with more storage capacity than 8GB.
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.
