Get your info at a glance: Check important info like phone calls, messages, and notifications from your favorite apps. Android Wear features always-on displays, so you’ll never have to move your wrist to wake up your watch.
Track your fitness: Set fitness goals, and get daily and weekly views of your progress. Your watch automatically tracks walking and running, and even measures your heart rate.
Save time with smart help: Receive timely tips like when to leave for appointments, current traffic info, and flight status.
Just say “Ok Google” to ask questions: like “Is it going to rain in London tomorrow?” or create to-dos with “Remind me to pack an umbrella.”
