Finally, the Apple Watch can now be paired with select gym equipment so data is more reliable and accurate.
"When we use gym equipment, it has data that the Apple Watch doesn't have and the Watch has data the gym equipment doesn't have so you end up with numbers - like calories and distance - that don't completely match", Lynch said during the opening keynote. If you're on the go and can't reach your phone, you'll be able to send funds to your contacts from the Watch. New colors of the Nike Sport Band are also available.
