Pretty good app. – Sonic Attack Free Review

What most of the people giving bad reviews don't realize is two things: 1) if the phone is on vibrate mode, it won't play any sounds (and yes, people are saying that) 2) if you turn of wi-fi, and I have tested it with this app, you will have a major decrease in ads popping up. And just in case, turn off your cellular data too.
