At WWDC 2017, Apple announced updates to proprietary software platforms, including the "smart" clock Apple Watch. Registered developers already have the first beta version of the operating system watchOS 4. Final update will be released this fall.

As the firmware testing becomes known, all the new features prepared by the developers of Apple. One of them is the congratulation of the owner of a smart watch on his birthday.

On the specified date, the Apple Watch screen will display a "Happy Birthday! ". After clicking on the message on the dial there will appear holiday balloons. The effect resembles the animation "Balloons", which appeared in iMessage in iOS 10.

Among other changes in watchOS 4 is worth noting the new application "Activity", which motivates the user and gives personal tips and tips. It also sets individual goals for a month.

The application "Music" in watchOS 4 has become more personal: it automatically synchronizes the mix from new music, selected and the music that the user listens to most often. It is enough to create a pair with AirPods and you can listen to music on the trainings and on the road.

The new "smart" dynamic dial Siri varies depending on the time of day and the user's schedule. It displays important information from the applications "Activity", "Alarm", "Breath", "Calendar", "Maps" and other.
