There are new heart rate notifications as well.
Ben Wood of CCS Insight says getting USA regulatory clearance for that is a milestone that underscores the company's leadership in health and fitness. Typically, smartwatches are marketed as consumer devices, not medical ones needing clearance.
During Apple's unveiling, American Health Association President Ivor Benjamin said capturing such data will help prevent stroke, heart failure and other problems.
It arrives with a new selection of animated Watch faces and the digital crown has been redesigned.
Apple also is expected to release an iPhone with minor updates to last year's $1,000 model and another version made of cheaper materials, including one with a traditional, backlit screen. The iPhone remains its biggest product, and the company is ready to make it even bigger.
For users on Apple's upgrade plan, the tricked-out iPhone XS Max will run them a cool $68.66 a month on a 24-month payment plan. Even so, the cheaper iPhone is still expected to sell for $650 to $750. It sets a new high price for an iPhone, starting at €1,279 in Ireland. And, the home button has been done away with on this model too.
The best part about the new Apple Watch Series 4 is the fact that it is powered by a new S4 chip which has a 64-bit dual-core processor.
The iPhone XR will feature an aluminium frame, a 6.1-inch LCD screen, just one rear 12-megapixel camera, facial recognition, and the company's new A12 chip. The displays on the watch are more than 30 percent larger with "minimal changes to the case size", he said.
The all new iPhone Xs will be priced similar to the iPhone X, and will cost you $999 for the base variant.
Apple iPhone XR, which is being touted as the most "affordable" one on the list, yet with a $749 starting price, it's safe to say there's nothing "budget" about it.
Kicking things off is the iPhone Xs - essentially the follow-up to the iPhone X. Made from surgical-grade stainless steel and featuring a new glass screen that's the most durable in any smartphone, the phone is available in gold, silver, space gray, and offers IP68 water resistance.
For everyone else, the annual Apple event where they reveal the latest iPhone, Mac, iOS, and Watch is happening later today.
