The fitness smarts have been augmented in a couple of ways. This watch has been know for its effectiveness as a fitness device over the years.

One of the main features of the Apple Watch 4 is the introduction of the new electrical heart sensor. This new feature helps take an electrocardiogram (ECG) reading using a new ECG app.

Although, The ECG feature was not available in the Apple Watch Series 4 at launch, but it was added through the watchOS 5.1.2 update, introduced in December 2018.

This feature amps up the Watch’s already impressive heart-rate monitoring features and notify if something irregular is detected. It has an improved tracker for checking how your ticker is beating. The Apple Watch Series 4 also features a next-generation optical sensor that can send heart rate notifications when it is too low or too high.

The ECG app is exclusive to the Series 4, because it relies on the electrodes running through the sapphire crystal-and-ceramic back and Digital Crown to take the reading.

Apple has received FDA clearance in the U.S. for these new features, hence, ECG readings are limited to the United States at this time.

The Apple Watch S4 can also detect falls, via its improved accelerometer, gyroscope and optical heart rate sensors. Fall detection works via a combination of G-force impact and detection of arm and hand placement when falling.

The sensors now have twice the dynamic range and can detect and read motion data eight times faster. Hence, the Watch can detect when you fall over. When the Apple Watch Series 4 detects a fall, it sends you an alert, which can be used to call emergency services if you’re injured.

If the Apple Watch Series 4 detects no movement for a minute after a fall, it automatically calls emergency services using the built-in SOS feature in the Apple Watch.

The speaker in the Apple Watch Series 4 has been overhauled. It’s now 50 percent louder than the speaker in the Series 3 models. Apple says the louder volume is great for phone calls, the Walkie-Talkie feature in watchOS 5, and Siri requests.

Water Resistance

The Series 4 models are rated for immersion in water as deep as 50 meters thanks to seals and adhesives. The speaker, which needs air to produce sound, is the only point of ingress. Therefore, it has been designed to expel water from itself using sound vibrations after exposure to moisture.
