Great - works better than others Ive used.

Ive used Chatterblocker on the PC for years. It is worth every penny. I work at a University where we leave our doors open most the time. This app allows me to keep my door open and to tune out conversations from the hall. It is simply amazing and much better than any competitor that Ive tried. I can also work at a coffee shop and easily tune out conversations.

My only gripe about the iPhone app is that it lacks the music sounds found in the pc version. Please add them to the next upgrade. Still 5 stars!
