MUVIZ is an app that displays a Music Visualizer beneath your Navbar while you are listening to your favourite music from your favourite apps. NO root required.
It’s quite hard to describe a visualizer with words so these pictures should make a lot more sense. Most of the time I have my phone in m pocket while listening to music but when picking up the phone and turning on the screen it really looks nice.
You can download it on Google Play for free*
The music player used in the above screenshot is Musixmatch, also installed on my phone. The app itself is a fully functional music player while also providing a sort of add-on to other player apps. For more info visit their website or Google Play.
