Amazing!
I did not have high hopes for this app, but I can say that this really does work. I am able to focus and avoid distraction while I am studying for tests and working on projects. While the sounds are initially somewhat jarring, after a few minutes I barely notice it since I am so focused on my work. Like another reviewer noted, its only a problem when the sound abruptly stops at the end of the timer cycle - Then I lose my concentration!
I hope that OS 4.0 offers the ability for this app to run in the background. Its a bummer when I have to navigate to some other app or to the home screen, which stops the app from running.
