Apple’s annual developers conference, known as WWDC, kicks off Monday at 1 p.m. EST in California.

The company is expected to preview new software features coming to iPhones, iPads, Macs and the Apple Watch. That could include improved health tracking tools and a dark mode on iOS devices.

“Apple is set to debut a new MacPro, as well as a macOS update and an iOS 13 preview,” reports news site Recode, citing The Verge. “[I]n addition to hardware and software announcements, developers will be waiting to hear updates on what the future of Apple’s other platforms will be.”

Software news is expected to dominate.

“The iPhone maker is expected to show off new versions of iOS, MacOS, WatchOS and TVOS,” according to tech news site CNET.

“However, if past years are any indication, hardware might be announced or teased, like a new Mac Pro, for example.”

CNET will be providing love streaming coverage.

Apple could also put iTunes, its main application for all music and video content, out of commission. The decision would not be a huge surprise. Apple has already broken out music into its own app while investing heavily in content and partnerships for a revamped TV app.
