I honestly don’t see the benefit of a “smart watch” that needs an iphone to fully work, and takes up both hands to use. Now you’re going to have people staring down at their arm, and using their other hand to operate it.
The car crashes are going to be that more spectacular. I predict a lot more broken forearms.
Who told you it requires both hand to use? Some apps do require both hands, but basic functions are handsfree. Time and alerts are handsfree. Want to see the time, raise your arm and look at the watch like you would any watch. Alerts turn it on and tap you on the wrist. If you decide it requires more, then you may need to take out your phone. The watch can operate independent of the iPhone for certain operations related to exercise such as running, walking, etc. It also responds to voice commands.
