The tagline:

Add them together. Multiply their power.

Nice wordplay. Here’s the subhead:

Get directions on iPhone and a tap on your wrist when you need to turn. Check your heart rate on Apple Watch and track it over the last hour, day, month, or year on iPhone. When you put the two of them together, they add up to so much more.

What follows is a series of use cases, each animated in a long single-scrolling series of “pages”, ending with pages to Shop Apple Watch and Shop iPhone. Take a look.
