I want to track my miles, heartbeat, as well as have easy access to my music. My iPhone 6 plus isn't working. It's too bulky while I'm running. Any suggestions? I was looking at the Apple Sport watch but don't know much about them. Update: Picked up the Apple Sport Watch. Was worth the extra cost instead of getting the Fitbit. I went out to purchase the Apple Sport Watch. I've had it for about a week and have been able to use it without my phone. I get to monitor my heart rate, activities such as standing, moving, exercise and calories. It's been working so far! I was going to give Fitbit a try but at the price they were going for I'd rather spend a little more and get the watch. I was washing dishes, and answered the phone with my watch. Pretty cool! I synced my Taylor Swift and Bruno Mars playlist music to my watch and I can actually listen without my phone.
