Android: YouTube's official app isn't super friendly to your subscriptions. While you can get a list of videos, that's about it. Tuber makes it easier to browse by focusing solely on your subscriptions.
The app features a few different panes. You can view your subscriptions as a list of "shows" (something YouTube's regular app frustratingly doesn't offer), browse by new videos, or search just an individual channel. The one major downside is that the player is only the embedded web player, but it still gets the job done.
