Drag race timer with start lights Five lights. One twitch.
The start lights time how fast you react before the car even moves. In a duel you race the iPhone next door, and Apple Watch taps every lamp onto your wrist.
Lights out, foot down.
With the start lights, all that counts is the moment the five reds go out. In a duel your mate's iPhone sits right next to yours, and the big moments earn you one of 24 badges. Closed courses only, obviously.
Who flinches first?
Two iPhones, one set of lights, no internet. Closed courses only.
Never miss the start.
Eyes on the lights, hands on the wheel: Apple Watch mirrors your iPhone and reports every lamp on your wrist. The iPhone does the measuring, the watch tells you.
