I'm fairly invested in the Apple system of devices (Mac at home/work, iPad for fun, iPhone always on me) but I'm still struggling to see the value proposition of the Apple Watch. It just doesn't seem like it adds anything beyond what I already use my iPhone for.
I went to the nearest Apple Store and asked this question, but the answer I got was quite unsatisfactory. I was told that it can track my steps, but the iPhone has already done that since 2013 with the M7 chip. I was told it can track my activity, but I already do that with Strava. I was told it can track my heart rate, but I already do that with a bluetooth band connected with my phone.
So really, does the Apple Watch do anything that an iPhone doesn't already do?
