VK U will allow you to listen to music from your smartphone even when you do not have access to the Internet. VK U has its own equalizer, which can be easily adjusted to suit your needs.
VK U has both positive and negative sides. No, nothing is perfect! The first negative country of VK U is the bugs associated with the departure and the search for tracks.
As for the first, crashes occur only when listening to songs for a very long time. And this happens quite rarely. As for the second, then don't even dream of finding your track from many others. You just won't be able to do it. There are exceptions to the rule, but not in my case.
VK U has support for both dark and white themes. And, both themes look very nice and neat. Nothing extra.
