As you can probably tell from all the recent travel-related posts, I'm on the road a lot as of late. One of the nicest surprises for me with the Apple Watch in my travels is walking directions on the Apple Watch.
I've always felt like walking around with my phone out for directions was like painting a sign over my head that says "I'm a lost tourist. Please come mug me." This was particularly true in San Francisco as I walked around at all hours of the day.
The Apple Watch removes that. Once you set a destination on your phone (or on your Watch via Siri), you can put your phone in your pocket and not look so obvious. Your directions will then begin showing up on your wrist.
The screen shows your estimated time of arrival and distance to your next turn. It's really quite nice. It gets better though.
As you are walking down the street, Apple Watch talks to you in secret code. If you are coming up on a right turn, you get a steady stream of 12 taps on your wrist. If you need to turn left you get three series of two taps to turn left. If you aren't sure, just look at your watch like you are checking the time when, in reality, you are getting directions like a secret agent in cold-war Berlin.
Once you arrive at your destination the watch vibrates again. Force tap your screen to stop the directions. Having done this now for several weeks, I can't imagine going back to getting walking direction on my phone.
