A fitting system with intelligent visual tools may included calculating a response curve of a hearing assistance device, wherein the response curve indicating sound level pressure level compared to frequency. Additionally it may include, displaying, on a display device, the response curve and displaying concurrently with the response curve, a visual cue, wherein the visual cue represents data including at least one of: gain of the response curve, a comparison between a target response curve and the response curve, and a comparison between binaural response curve.
