Apple Watch Series 4: Bigger screen with EKG sensor

Smartwatches
That Apple Watch is back. Fourth generation, the Apple Watch Series 4, what does it bring to the table this time? Well, it's made a big leap in medical tech. The optical heart rate sensor is now designed to be more accurate, to detect atrial fibrillation. It's FDA-cleared for that, so if you have any situation where you have a heart arrhythmia, The Apple watch should now be even better at doing that. The second thing you will now do is scan for if your heart rate is really high or if your heart rate is really low. The low is a new feature that's on the Apple watch. The third part is using a whole new sensor that's on the back electrodes and what that's gonna do is provide an electrocardiogram That gets completed by holding your finger on the digital crown and taking a spot heart rate reading. That feature isn't on here yet, but it's coming later on this year. And this is the first device that's had ECG in any sort of smart watch or wearable over the counter. That's a really big step for the Apple Watch. Last year there wasn't an ECG or heart rate band That was sold separately, but now it's being built-in to all the devices. The Apple Watch series 4 also has a lot of different design changes, mainly that the display is bigger. Now, it's 40 and 44 millimeters but the case is still pretty compact. That means that the smaller sized Apple Watch actually feels like it has is about the same size screen as what was the larger size before. The watch faces now have been redesigned. There is no watch face store. But there are a number of dynamic watch faces. There are ones that have crazy fire and particles. There are ones that have more complications, which means that you can launch bits of information faster, which is great. However, there are some not always on display. Other smart watches do always have on displays. And the Apple watches still staying that course. So it's also a watch they're going to have to Raise to look at the time. The crown is new, there's haptic feedback, and the watch also has the ability to have more accurate, not just ECGs, but more accurate heart rate, and Apple claims more accurate fitness tracking in general. The accelerometer and the gyroscope in here are new, and what that enables is fall detection. Which is supposed to work in association with SOS messages so that if you fall and you stay there, it should be able to send a message to get help. However the sub-watch does not have sleep tracking, something that we were expecting, perhaps not on this one because battery life is basically the same as last year Which means that it will last probably about a day and a half. But don't expect anything more than that, you're gonna have to put it back on the charger. The Apple Watch Series 4 starts at $399, going to $499 if you want cellular built-in. And by the way, Series 4 is supposed to have better cellular reception than [CROSSTALK] Because the back of the watch is now ceramic-backed, which should allow radiowaves to pass through more easily. Now, it ramps up in price after that. If you want a stainless steel, like the one I'm wearing, that has cellular, this thing can cost $699 or more. But that's always been the case with Apple watches. They can get expensive. More to come as we actually wear one, and review one But the Series 4's best features might be the ones that are medical. I'm here at the Steve Jobs Theater, I'm Scott Stein.
