At its 2019 iPhone event, Apple refreshes its wearable OS for the Apple Watch with a focus on health.

WatchOS 6, coming Sept. 19 for Apple Watch Series 3 and later, will help track menstrual cycles and fertility windows through a new app called Cycle Tracking, prevent gradual hearing loss through another app called Noise that notifies you when you are in a loud environment, and directly download apps through an App Store on the Apple Watch (instead of using your iPhone). The Apple Watch Series 5 smartwatches are coming Sept. 20, and Apple said WatchOS 6 will be available for Apple Watch Series 1 and 2 later this fall.

With the new update, Apple is rolling out three health studies that tie into the company's focus on health: Apple Hearing Study with the World Health Organization and University of Michigan, Apple Women's Health Study with Harvard and National Institutes of Health, and Apple Heart and Movement Study with the American Heart Association and Brigham and Women's Hospital. You can enroll in studies through the Apple research app later this year, Apple said.
Apple also expanded the capabilities of its digital search assistant Siri on WatchOS, which can now identify songs and bring up web results for your search queries, and the Reminders app Other additions include Voice Memo for recording voices and reminders, and Calculator, so you tap out calculations on the Apple Watch's tiny screen.

And of course, no WatchOS update is complete without a number of new watch faces. There's a two-toned interface called "gradient," and "infograph modular," which displays several watch complications on one screen that can be swapped around. A few new complications include player controls for your audiobooks, and another that works in conjunction with the Noise app to show your environment's decibel levels.
These updates, alongside the company's signature Apple Watch smartwatch, continue Apple's ambitions of seamlessly integrating software with its popular hardware devices. Apple's ability to control every aspect of its products -- something that began when Steve Jobs and Steve Wozniak founded the company in 1976 -- has been key in making it the most powerful company in tech.
