The Google Pixel Watch combines its own Wear operating system with Fitbit health tracking. The watch can be paired with Android devices only and is 4G-compatible, which means it can function on its own without being near a phone – but to do this it requires its own data plan. The tech giant did not reveal a price for the wearable, but it said would be a “premium product” when it launches in the autumn. It faces stiff competition from the likes of Apple and Samsung, which are already market leaders in smartwatches. DO smart watches ha health effects ?
