Besides releasing the third beta of iOS 9, Apple has also released beta 3 of OS X 10.11 El Capitan and beta 3 of WatchOS 2. The new watchOS 2 beta comes two weeks after beta 2 was pushed out for testing purposes and continues the development roadmap of the operating system that was initially introduced during this year’s WWDC keynote in the beginning of June.
Like the initial betas, watchOS 2 beta 3 requires an iPhone running iOS 9, which is also in developer preview stages. If you’re already running watchOS 2 beta on your Apple Watch, then simply launch the Watch app on your iPhone, then navigate to General > Software Update to get beta 3 on your Apple Watch.
If you’re starting fresh however, then first you need to install iOS 9 beta on your iPhone, rest is the case of downloading a provisioning profile from the Apple Developer Program website in order to push the watchOS 2 update onto your Apple Watch.
watchOS 2 represents Apple’s first attempt at revamping the software that powers the Apple Watch. After initially launching the product with the first version of watchOS, the second major iteration introduces a number of powerful additions such as the ability to install and run truly native apps. Developers can now also build apps that take advantage of a lot more of the device’s built-in sensors.
