It won't work with any iPhone, just like an Apple Watch won't work with any Android device.
So they're not competitors by any means.
That was the big change Google made with Wear OS 3. They killed iOS support.
We saw this with the Galaxy Watch 4. Samsung ditched Tizen and went to Wear OS and killed off any support for iOS in the process.
I actually liked my Active 2 and was looking forward to the GW 4. I like round watches.
Did the industrial design team and OS design team never meet during the process? Because that interface doesn't match the form factor that they've jammed it into. Awful. 😂
I agree about the look of the hardware but I actually like the OS interface, it is a clean look, not confusing, not a mash of those flat circular icons on the Apple Watch, not the second rate look of the Samsung Watch interface, I think it has promise.
Of course as people here noted, Google has a history of abandoning its products, will they actually try to build a solid Apple alternative ecosystem? Their video presentation showed some nice ways in which all of their products integrate, not certain it is any different than how Apple's products integrate, but is their voice assistant better than Siri, I don't know.
And the Pixel Watch looked crippled in the watch faces they presented, where are the different complications, do they have them but did not want to show them because they don't want to appear to compete with the Samsung watch line? Can they display stock quotes, news headlines, more granular weather details like wind speed and direction?
I just want to see more solid competition, more Apple alternatives, not certain Google will sell these in numbers that even get close to Apple, but I hope they sell enough to keep the ecosytem viable to the Google CEO and team.
Oh and the security and privacy that was touted in their presentation, I hope it is true and effective, I would like to see someone credible parse the privacy differences between the Google and Apple ecosystems.
