Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. iPhone downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About Audio Frequency Analyzer
"Audio Frequency Analyzer" is a powerful real-time audio analyzer (RTA) app for iPhone.
With its simple operation, you can easily measure and evaluate your sound environment.
This app measures the frequency response in 30 split band scale of 1/3 octave in real time. It can also display the FFT analysis results.
It supports calibration for 1/3-octave bands. By adjusting the characteristics to match not only the built-in microphone but also your external microphone, it achieves high measurement accuracy.
"Audio Frequency Analyzer" can be used for various applications, including sound room tuning, speaker settings, audio equipment testing, stage setup measurement, sound mixing environment evaluation and noise environment investigation.
Features:
- Frequency spectrum response measurement of 1/3 octave unit, 30 bands. (OCT)
- FFT Analyzer (FFT)
- Observation frequency range: 20 - 23000 Hz
- Logarithmic amplitude display.
- Touch-scroll function to adjust visible amplitude ranges.
- Display the measured value of 1/3 oct bands at OCT mode. (dB@OCT)
- Function to change the graph slope at FFT mode. (Slope): -3dB/oct (less than 1kHz), +3dB/oct (1kHz or higher)
- Peak hold function. (Hold)
- Average display function. (Avg): Time linear averaging. Fast-2.56sec, Slow-12.8 sec
- Display response control. (Fast/Slow)
- Reset of Measurement display position. (Scroll)
- Snapshot of Measurement display. (Snap)
- Calibration function in OCT mode. (Calibrate): 1/3 octave band offset and total offset setting.
- Supports built-in microphone, headset microphone, and external digital audio connection.
Note:
The first time you access your microphone and photos after installing the app, the iOS system will ask you for permission to access them. If you have not enabled this setting, the app will not be able to access them due to iOS system privacy restrictions. Please enable the access permission in the iOS setting "Settings > Privacy & Security > Photos or Microphone".
