Just tries to masks external sounds. :(

Somebody elses review said that this app just masks sounds with louder sounds. Somebody else said its like your car stereo trying to increase the volume of the audio depending on the speed in which youre driving. It just plays sound that fluctuates when loud noises happen. I was really excited about this app but all the negative reviews are true. It does not cancel out sounds. It just tries to mask surrounding noises with a louder sound. Very disappointing. And furthermore disappointing that I wasted $5 on it. Boo urns.
