Have you heard of Google Uptime app that makes YouTube video more interactive?.

Google Uptime

This app called Google Uptime was just launched by Google; it’s an app that lets you watch YouTube videos together with your friends. Uptime basically takes existing YouTube videos and makes them more interactive by letting you watch them with your friends. 

You can see where — time-wise — your friends are in a video as compared to you. You’ll also see reactions in the form of sparkles or different cartoon faces. 

With This App, You Can

>> share YouTube videos with friends, and then watch them together in real-time.

>> Users can chat with each other, and leave comments and emoji layered on top of the video

>>Follow other users within the app

Google first published Uptime in March as an invite-only limited beta test, but the app is now freely available to all iOS users but not yet available for Android.

I don’t know why Google didn’t integrate this features into is YouTube app but Google claim the Uptime app was built by Area120, an experimental research and development unit launched by Google last year to turn left-field ideas from Google engineers into actual products.
