Hello friends . I share you my personal experience . Musically app is cool aap .after the installing the app the app working perfect . But its perfect only fast mode .when you go to slow mode in a musically the app was not perfect . This fault only in android user . But in apple user the all mode are work perfect . Fast and slow mode work perfectly. In my opinion I give 3* /5 for android phone. But 5* /5 for ios user . In free time use this application. After use this musically application you feel like a star .How my review look like .please share your opinion in my comment box
