What can an Apple Watch do without an iPhone

 

 

Number 2. Fitness Tracking

The Apple Watch comes with a slew of fitness features that can act on their own. The Generation 6 Apple Watch that just released helps you monitor your heart rate, take an ECG straight from your Apple Watch, and now even track blood oxygen levels. Eventually, the data is synced to your iPhone, but you can take the reading and view the result directly on your watch first.
