Doesn't use ambient mic and animation is a bit choppy

App only uses mic on the bottom of the phone and doesn't use the ambient mic on the back of the iPhone to measure more accurately, animation of the dial is a bit choppy as well.

Fluctuates betwwen 50 and 90

Bust scale is 0 to 120, so it is really hard to see. It should also calibrate to bottom out at 20db, but doesnt yet!
