From Rogue Amoeba. Christa Mrgan runs through the creation process of their new audio recording app, Piezo.
We wanted the app to be obvious, convenient and fun. I knew from the beginning that I wanted it to have analog VU meters with bouncing needles, a clearly-labeled source selector, and a big, friendly record button. I also knew I did not want multiple buttons for simple recording options. A binary system was far preferable to the unnecessarily complicated array of options you see in, say, elevators in two-story buildings1.
