Interesting, but can’t read the Japanese fonts.

App seems pretty good but despite changing both note displays to CDEFGAB I still get large Japanese characters on the range function.

Response from developer

Thanks for your feedback! This issue has been fixed in the latest update. Please update the app and check again.

Flutters

I wanted to use it to check pitch when playing chords on ukulele, but it flutters back and forth and doesn’t settle. (Admittedly, that could be my playing.) Also, there is a banner of naked pictures across the top.

FAQ

What does this app do?

This app analyzes real-time audio from your microphone to display musical note, pitch, octave, frequency, and waveform information. It also includes a metronome feature for tempo practice with sound and vibration cues.

How can I use this app for vocal exercises or measuring my vocal range?

The app displays extended vocal ranges such as hihi A and lowlow A, making it suitable for measuring your vocal range. You can also use it for vocal exercises and karaoke practice to improve your pitch accuracy.

Can I use this app as a tuner for my instruments?

Yes, you can use this app as a basic instrument tuner. No special settings are required, but switching the large center display to 'C, D, E, F, G, A, B' notation might be more convenient for tuning.

How do I adjust the microphone sensitivity?

To avoid picking up small sounds and background noise, slide the 'Microphone Sensitivity' bar in the upper-left corner upward. This will help the app ignore softer sounds and focus on the intended audio input.

What are the customization options for the display and metronome?

You can customize the display notation between sharp and flat, and choose between 'Do, Re, Mi' or 'C, D, E, F, G, A, B' for the large center display. The metronome allows you to set your desired tempo and practice with sound and vibration cues.
