PWA support was earlier added for YouTube Music and YouTube TV.
YouTube site can now be installed as a Progressive Web App (PWA) for quick access. PWAs are – in oversimplified terms – web pages that can work like apps on your phone. PWA support was earlier added for YouTube Music and YouTube TV. The support was incorporated into the main YouTube site over the past few days. Google had recently announced that it was bringing Stadia to iOS as a PWA. Google Photos was made available as a PWA back in 2018. Twitter had also launched its PWA in 2018.
As explained by Google Developers, PWAs use modern Web capabilities to deliver a user experience that is similar to using an app. Pages in browser tabs can deliver immersive, high-level apps.
