Is the iPhone app required?
Yes. Traffic Blinker is an Apple Watch app, and an iPhone is required to use it.
The Apple Watch can only be connected to an iPhone. Therefore, we recommend using an iPhone to install the Traffic Blinker app on your Apple Watch. Once paired with your iPhone, you can start the Apple Watch app directly from your device. It will begin the bike workout activity and display the blinker, ready for your ride.
