Pitch Checker: Chromatic Tuner12.3.0 - App Store

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.

To prevent this, slide the “Microphone Sensitivity” bar upward to ignore softer sounds.
