After reading some of the reviews, I almost didnt buy this app. Well, I did and it was worth it. My 10 lb schnoodle has been keeping me,my wife, and neighbors up ever since we moved into a new apt. I got this app and it did not affect her at first. Desperate to see some reaction, I grabbed my computer speakers and maxed out the volume! Within a few minutes of barking, she was as annoyed as we were. So, I write this review with a full nights sleep! I did put the sensitivity on low because med and high pretty much went off when she breathed! Definitely worth a dollar to be able to smile at the neighbors again!
