In the video clip below you can see what's new in watchOS 3 implemented by the Apple company for the Apple Watch, those from Cupertino taking great care to radically improve the performance of the smart watch, as requested by the users.
I explained to you last night how Apple grew Apple Watch performance, but now we are talking about all the watchOS 3 novelties offered to users, they being available in quite a large number, but not all of them represent Apple's innovation, some being taken over from competitors.
What's new in watchOS 3 will most likely be improved or modified by the fall, when the final version of the operating system will be released, so some of what you see below might work slightly differently.
