How different is the Apple Watch Series 4 from the Apple Watch Series 3?
"Everything about it has been redesigned and re-engineered," Apple COO Jeff Williams said during Apple's event on Sept. 12, 2018.
The Apple Watch Series 4 smartwatch includes a new display, with the screen reaching the edges of the device, and curved corners to match the shape of the watch. The screen is more than 30% larger than that of the Series 3. The device is also thinner, with less total volume than the previous version. The Apple Watch Series 4 also includes up to eight complications, compared to six in the Series 3, which users can customize to their liking.
The digital crown has been completely re-engineered to include haptic feedback, giving the device a more responsive feel. This is especially helpful for podcast and calendar apps where users need to precisely flip through each item, Williams said at the event.
The watch's speaker was redesigned to be 50% louder, which will make it better for phone calls, walkie-talkie use, and Siri use, Williams said at the event. The microphone has been moved to the opposite side, as far away from the speaker as possible to reduce echo and make calls clearer.
The back of the Apple Watch Series 4 is made entirely of black ceramic and sapphire crystal. This allows radio waves to pass through both the front and back of the device, making the Series 4 better for staying connected.
The Series 4 phone contains a new S4 chip, and a 64-bit dual core processor designed by Apple that delivers up to 2x faster performance than the Series 3.

What new health features are in the Apple Watch Series 4?
Apple added a number of new health features to the Series 4 watch. These include next-generation accelerometers and gyroscopes—which power activity tracking—that offer 2x the dynamic range.
The Apple Watch Series 4 can recognize if a user falls, slips, or trips. After detecting any of these actions, the Apple Watch Series 4 will deliver an alert asking if the user wants to initiate an emergency call. If the user is immobile for one minute, the phone starts the call automatically, and sends a message with the user's location to their emergency contacts.

The watch has several new heart rate features, which includes:
- Notifying the user if their heart rate is too low;
- Screening a user's heart rhythm in the background, and sending a notification if it detects an irregular rhythm that appears to be atrial fibrillation (AFib); and
- Using built-in electrodes that can perform an ECG on a user in 30 seconds.
The watch is the first ECG product offered over the counter directly to consumers, Williams said at Apple's September 2018 event. Users can take an ECG at any time with the watch, and upon completion, will receive a heart rhythm classification. All records will be stored in the Health app in a PDF that users can share with their doctors if they so choose.
All health and fitness data is encrypted on the watch and in the cloud, Williams said at the event.
The Apple Watch Series 4 is "the ultimate guardian for your health," he added.
