- Toggle between sharp and flat notations

■ FAQ
Q. I want to measure the vocal range.
A. The app also displays ranges like hihi A or lowlow A. Feel free to use them.
Q. The pitch is displayed even when its quiet.
A. Due to very small noise, pitch may be displayed even in completely quiet places. To avoid picking up noise, slide the "Microphone Sensitivity" bar next to the pitch display upward to ignore small sounds.
Q. I want to use it as a tuner.
A. You can use it without any specific settings, but changing the display notation from "Do, Re, Mi" to "CDEFGAB" in the center is more convenient. Press the gear icon in the top right corner, then tap the right side of "Display notation" under "Large display notation."
