Can you live stream the workout screen from Apple Watch to iPhone? I use Apple Watch for cycling and would love to see my live workout data on the phone (mounted to my bike) rather than the watch (on my wrist)

Hello, Harry_pearce! Thanks for reaching out to Apple Support Communities. 

We've reviewed your question and it looks like you want to view the Apple Watch Workout app details live on your iPhone, as you are mid-workout. We understand how that would be handy in your situation with your bike, so allow us to clarify. There is not a way to mirror the dat on your Apple Watch onto your iPhone screen while working out. There may be a third party application that could accomplish this, but there is nothing built into the watch currently like that.

The article that your question was linked from is very helpful when considering the different ways you can use the Workout app on your watch: Use the Workout app on your Apple Watch.

If you have follow-up questions, please let us know. We're here for you. Have a fantastic day!
