You can pause the analysis with a tap, allowing you to review the results at your own pace. The display also supports notations such as low A, mid2 A, hihi A, etc.
■ How to Use
Simply launch the app, and it will automatically measure the pitch of sounds captured by the microphone — whether voice or instruments. To avoid picking up small sounds and background noise, slide the “Microphone Sensitivity” bar in the upper-left corner upward.
The metronome can be used by simply setting your desired tempo.

- Toggle between sharp and flat notation
- Change the large center display notation (Do, Re, Mi / C, D, E, F, G, A, B)

■ FAQ
Q. I want to measure my vocal range.
A. The app displays extended ranges such as hihi A and lowlow A for your reference.

A. Even in very quiet environments, tiny background noise may be detected.
To prevent this, slide the “Microphone Sensitivity” bar upward to ignore softer sounds.
Q. I want to use it as a tuner.
