This app can be used as a standard, a drop, a double drop, an open, or a standard minor. It is perfect for playing the guitar, bass, ukulele, violin, viola, and cello.

The display is a graph with a line and two labels. The horizontal axis is the frequency, and the vertical axis is the pitch. The display is a standard format, so the horizontal and vertical scales are both equal. The value on the graph is the difference between the current pitch and the standard pitch. The horizontal axis is the difference, and the vertical axis is the frequency.

The graph is in the form of a circle. The frequency and the pitch are both represented by a circle. The center of the circle is the point where the graph line crosses the horizontal axis.

The value on the graph is represented by a color. The color changes according to the value. The maximum value is 100, and the minimum is 0.
