can you listen to youtube music on apple watch without your iphone

Hi sulijiso,

Currently the YouTube app is only compatible with the iPhone, iPod touch, iPad, and Apple TV. You can view that information here:

YouTube: Watch, Listen, Stream on the App Store

If you have further questions, reach out to the app developer. You can find steps for doing so here:

How to contact an app developer - Apple Support

Have a great day!
