Apple unveiled its Series 4 watches and three new iPhones at an event in Cupertino, California, on Wednesday. The new watches feature enhanced health capabilities, including more precise fitness tracking, electrocardiogram capabilities, and a gyroscope that knows if wearers fall, all with FDA approval. It starts at $399 with GPS. Meanwhile, the stainless iPhone XS has a 5.5-inch edge-to-edge screen — a bigger display than a Plus model, but on a smaller device — and the iPhone XS Max features a 6.5-inch display, iPhone's biggest yet. Both phones have enhanced FaceID and improved processing systems. There's also a lower-grade iPhone XR made of brightly-colored aluminum. The XS starts at $999, the XS Max at $1099, and XR at $749.
