The Apple Watch does not have Wi-Fi, it uses the Wi-Fi in the iPhone, but don’t get too worried just yet. By itself, the Apple Watch can track fitness data, play music stored on the Watch, and make purchases using Apple Pay. The Apple Watch connects to the iPhone using Bluetooth 4.0. Do I need to carry my iPhone on me at all times in the office and at home? What if my iPhone is in my bag, at my desk, or in my room?.Can the iPhone be in my bag in the corner, in my locker in the locker room, or does it have to be strapped to my upper arm or in my pocket? Using the Apple Watch at the gym for workouts and activity monitoring.This is an important question for many situations, including: The question is: How far does the Wi-Fi/Bluetooth connection reach between the Apple Watch and iPhone? I’m guessing that many people already wonder this and many more will wonder this as soon as Apple Watches begin shipping. I had a question today, so I thought I’d research the answer and share it with you.
