Apple today seeded the third beta of an upcoming watchOS 3 update to developers for testing purposes, two weeks after seeding the second beta and more than a month after first unveiling watchOS 3 at its 2016 Worldwide Developers Conference.
The third watchOS 3 beta can be downloaded through the dedicated Apple Watch app on an iPhone by going to General --> Software update. To install the update, the Apple Watch must have 50 percent battery, it must be placed on the Apple Watch charger, and it must be in range of the iPhone.
watchOS 3 introduces significant changes to the watchOS operating system. A new dock, accessible by pressing the side button, replaces Glances and houses 10 favorite first and third-party apps. Apps on the dock are kept continually up to date and are stored in memory for instant launch times.
Activity Sharing options allow Apple Watch owners to share workout and activity information with friends, and there are new options for Wheelchair users. A Breathe app guides users through daily deep breathing sessions, an Apple Watch can unlock a Mac, and Apple has added apps for Reminders, Find My Friends, and accessing one's heartbeat.
Watch faces support more complications, there are three new watch faces to choose from, including a new Activity watch face, and an SOS feature will make sure an option to get help in an emergency is always right at your fingertips. On the iPhone, there's a new Face Gallery for customizing Apple Watch faces, and watchOS 3 allows the Apple Watch to be located via Find My iPhone.
