Vidmate cant be found into the play store it can be downloaded from 9 apps its UI simple and easy to use I have used this app and its my favourite since last year but now may be the developer are not considering the problem on it such as if u close all the app but the sound still continue towards ur phone background u can download it and use it. But may be it has the touch competition with snaptube is also just like vidmate but it can be found on play store I think u should try both.
