PIP Tube is a completely Made in India app that can help you watch Tube videos through Floating Window. With it, you can watch Tube videos while browsing the web and other things, completely free your phone and it doesn't require any permission except a working internet (of course).

PIP Tube is always on top of other applications, so that you can ensure that the player is always on top when doing other things.

Use:
Just play any Tube video and while playing click on the red floating button, in bottom corner. Voila! You're playing videos while working around.

Note:
Due to Tube privacy policy, background playback is no longer supported
