## Pitch Checker Description
The app analyzes real-time audio from your microphone and displays musical note, pitch, octave, frequency, and waveform information.

It also includes a Metronome feature (Beta), allowing you to set the tempo and practice with sound and vibration cues.

■ Usage Examples
- Measure vocal range
- Practice absolute pitch
- Detect the musical notes of a song (pitch detection)
- Vocal exercises
- Karaoke practice
- Improve pitch accuracy
- Measure frequency
- Voice training
- Basic instrument tuning (use it as a tuner)
- Do, Re, Mi note detection
- Rhythm practice using the metronome

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.

■ Settings
Tap the gear icon in the top-right corner to access the following settings:
- Toggle between sharp and flat notation
- Change the large center display notation (Do, Re, Mi / C, D, E, F, G, A, B)
- Set the reference pitch
- Adjust pitch detection speed
- Set the metronome tempo

■ 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.

Q. Pitch is displayed even when it’s quiet.
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.
A. No special settings are required. However, switching the large center display from "Do, Re, Mi" to "C, D, E, F, G, A, B" may be more convenient.
Tap the gear icon and change the “Large Display Notation” setting.

■ Other Information
Permissions:
- Microphone: Used to analyze audio input

## Pitch Checker Reviews in United States

### ***** "Nice!"
Love the features!
-- iReviewAppsOccasionally, 2024-10-17

### ***** "Best thing since the flatted 5th"
Simple, Precise, Transparent. 🔥🎶
-- DeQyd, 2024-07-18

### ***** "good app"
ever tried to learn a tune you made in your head on piano? this app helps a lot with that
-- fishingfoodfan66332, 2024-07-03

### ***** "Very useful app! The pitch recognition is AMAZING!"
I have been looking for an app that can measure extreme pitches, and this one, out of every single one I can find out there, this one is the best. This app can not only detect pitches instantly, but it can recognize a few pitches above and below the human range of hearing! It can also recognize pitches on a pipe organ with a 32’ stop. This app is the only one that does it. It can recognize pitches as low as 14 Hz, and as high as 21,500 Hz. The range that this app can recognize is the broadest of all pitch checking apps, from A-1 to E10. If you are looking for an app to use as a tuner, and an app for measuring pitch for anything, definitely buy this app! You will love it! :D ❤️ 🥳 💕

App is some boof
