After Apple announced that the
next version of the iOS will not support a native YouTube App, Google has
formally launched a replacement mobile app for Apple devices. App is available
in Appstore as of this writing!
The new app is said to have improved
search functionality and more sharing options. This app will let you subscribe
to channels like what you do in the web version.
Google also cited that they are
developing an optimized YouTube app for iPad. Having a Google-powered YouTube
app in iOS means better support and services.
