The Best Progressive Tone Alarm – Progressive Alarm Clock Review

This app is just what I was looking for. I have it set to chime or gong with the sound of a Tibetan signing bowl and then gradually increase in volume as the interval between gongs decreases. You can adjust most parameters to come up with the perfect program for you. It is far superior to the mechanical zen clocks that cost a whole lot more and are not nearly as reliable.
