Here are the new features coming to the Apple Watch

After the call is complete, it will let you automatically alert emergency contacts with a map of your given location. If you're in a different country, it will know to dial that country's emergency service number.

You can "compete" with friends and family also wearing an Apple Watch by tracking how your activity is comparing with theirs. You can also communicate with them through the Activity app using Smart Reply, Scribble, or by leaving an Audio message.

It tracks wheelchair pushes and will say "Time to Roll" instead of "Time to Stand."

You can also set alerts to get reminders about practicing deep breathing.

You can change the font on the numeral-style watch face, pictured above.
