Apple Inc introduced its largest iPhone ever and a new line of watches that can detect heart problems on Wednesday as it looks to get users to upgrade to more expensive devices in the face of stagnant global demand for smartphones.

New iPhone Release

The relatively small changes to its lineup, following last year’s overhauled iPhone X, were widely expected by investors, who sent the company’s shares down 1.5 percent.

“It is pretty consistent with past iPhone release days where we see short-term sell the news but things will probably get a lot better in the weeks and months ahead, particularly with a strong holiday sale season expected,” said Jake Dollarhide, chief executive of Longbow Asset Management.

Apple’s new phones are the XS, with a 5.8-inch (14.7-cm) screen, starting at $999. The XS Max, the largest iPhone to date and one of the biggest on the market, has a 6.5-inch (16.5-cm) screen, and starts at $1,099.

The company uses the ‘S’ suffix when it upgrades components but leaves the exterior of a phone largely the same. Last year’s iPhone X – pronounced “ten” represented a major redesign.

It also introduced a lower-cost 6.1-inch (15.5 cm) iPhone Xr made of aluminum, starting at $749.

With two phone models starting at $999 or higher in the United States, Apple appears to be taking advantage of a strong U.S. economy, low unemployment, and rising household wealth. The median U.S. household income rose for a third straight year in 2017 to the highest on record since 1967 by one measure, government data showed on Wednesday.

Apple, which is looking for ways to lessen reliance on phones for revenue, opened its event by announcing the new Apple Watch Series 4 range with edge-to-edge displays, like its latest phones, which are more than 30 percent bigger than displays on current models.

It is positioning the new watch as a more comprehensive health device, able to take an electrocardiogram to detect an irregular heartbeat and start an emergency call automatically if it detects a user falling down, potentially appealing to older customers.

The U.S. Food and Drug Administration said it worked with Apple to develop apps for the Apple Watch and has been taking steps to ease the regulatory pathway for companies seeking to create digital healthcare products.

“This is a pretty big deal,” said healthcare tech analyst Ross Muken at Evercore. “This update really establishes the company’s increasing efforts to push the watch as a serious medical device. Apple seems to be diving into heart disease first, the most common cause of death around the world, making serious moves as a health company.”

Shares of fitness device rival Fitbit Inc fell about 3.7 percent after the Series 4 announcement. Shares of Garmin Ltd lost some earlier gains and were flat in midday New York trade.

Executives made the announcement at the Steve Jobs Theater at Apple’s new circular headquarters in Cupertino, California, named after the company’s co-founder who wowed the world with the first iPhone in 2007.
