I've registered at Udemy.com to watch some (free) online tutorials (Coding/Cooking/Guitar/Photography/...).
Everything is cool besides the fact that Udemy didn't offer an option to cast the video stream from a mobile device to the TV (even if using the Chrome browser)

So, what I've found on the web is [MomoCast]. Yes, indeed, without a doubt there are a thousand more Chromecasting apps availabe.
Therefore feel free to recommend your favorite one - and why that's the best ever ever ever ... (even for Android!)
