The Worldwide Developers Conference is Apple's way of gaining cred with the developers who build the applications that make its phones, tablets, watches and computers worth their costs.
At the annual confab in San Francisco on Monday, Apple CEO Tim Cook didn't disappoint the global audience of developers when he revealed the following numbers:
Apple's App Store has passed 100 billion app downloads, Cook noted, and has paid out more than $30 billion to developers.
"Everything's going great," said Cook at the beginning of his keynote speech, before he and other Apple executives gave the audience a peek under the hood of the company's other flagship products.
Among the key stats revealed Monday:
1 million locations accepting Apple Pay: Apple's mobile payments system is growing. The number of purchases made with Apple Pay has doubled, and the number of merchants accepting Apple's payment app will surpass 1 million locations next month, said Jennifer Bailey, vice president of Apple Pay, on stage Monday.
Bailey also saidwhere it "will launch with eight of the most popular banks with more coming this fall." More than 70 percent of credit and debit cards in the UK will be compatible with Apple Pay, according to Bailey.
55 percent of Mac users have adopted Yosemite: Apple wants you to know that its Mac OS X software is popular -- and that it's really fast.
"Yosemite has the fastest adoption rate for any PC operating system ever," said Craig Federighi, Apple's senior vice president of software engineering, noting that 55 percent of users have adopted the computer operating system since its release last year.
Federighi said speed is powering the software's popularity -- and that will continue with El Capitan.
Federighi introduced the new version of Apple's OS X on stage Monday. He said the operating system is "seeing 1.4x acceleration in app launching, 2x improvement in snappiness of switching apps, twice as fast to get new mail messages, 4x as fast to get into preview."
Apple Maps gets 5 billion requests per week: Federighi said Apple has continued to invest heavily in Maps. The mapping app is getting an update in iOS 9, the latest version of Apple's mobile operating system. Maps will have a new feature called. Transit will be supported in a handful of cities initially, including New York, Baltimore and San Francisco. It will also be supported in 300 cities across China.
Siri answers more than 1 billion requests each week: Federighi said Siri -- Apple's voice recognition software -- "has quietly become popular." Each week, Apple's voice recognition software answers more than 1 billion requests.
Siri has also been getting better at hearing what its users are trying to say. Over the past year, Siri has gotten 40 percent faster at responding to users, Apple said, and it has had a 40 percent reduction in its word-error rate.
