Frequency measurement tool
Operation explanation
When you press the start button, measurement starts.
The waveform of the measured sound is displayed in gray (updated every time) at regular intervals (125 ms).
Upon detecting vibrations at regular intervals by internal processing,
The frequency (Hz) is displayed. (For reference, scale (Doremi is also displayed)).
In addition, the waveform when vibration is detected is displayed in red (fixed), and processing of vibration frequency
The maximum value used is displayed as a point.
(You can visually check if the measured sound is correct.)
Press the start button again to start the next measurement.
The detected frequency is added to the cumulative measurement value.
The cumulative measurement value holds the latest 10 cases and also displays the average value.
Adjust the measurement sensitivity with the sensitivity adjustment button.
As the sensitivity decreases, the change in the small sound is sensed.
(However, it makes it easier to pick up noise.)
Button Explanation
Start button: Start measurement.
Stop button: Cancels the measurement.
Clear button: Clears the cumulative measured value.
+ - Button: Adjust measurement sensitivity.
The detectable frequency is less than 400 Hz.
Note: This tool uses the recording function of Android,
Since it depends on the model, it does not guarantee the accuracy of the measured frequency.

Those comments about the app being upside down may not know much about sound test equipment. The app is upside down so you can hold the microphone on your phone away from you to measure the sound. I would say that was very clever to make the app that way but the app needs to be in english.
Useless. No frequency readout at all. Only thing that happens on the screen after pressing the start icon is that the green line reacts to sound. No indication of what frequency it is. Waste of time.
Perfect for Ducati Belt Tension reading. Simple interface and holds the reading. And there's now a setting for Upside Down in case you prefer to hold it that way!
It works as intended... And for the record the interface is upside down coz a phone mic is at the bottom of the phone
Not live reading so easy to misread. . Upside down screen is a clever plus so I add a star to it...needs fixing and translate from Japanese
This app senses the frequency accurately but they need to change the language to English.
so i think what happened was some japenese guy was just starting to learn how to code, and he started making a program but stopped half way through and uploaded it to the play store
it is in japanese upside down and messes uo the phone! stay away!
This app works, but gives Hz reading in chinese language
Trying with sound of average 430 Hz to 440 Hz, mostly acurate
it was in Chinese didnt do anything the pictures show
No english - flips the screen
This tool doesnt work
Can't read it
Didn't do what it said it would... Just needed a basic sound measurement, and while the sound registered, it didn't actually show like it does above.
The chinese symbols are coming, which are not understandable.
Don't read jap

Brilliant app. The one tool here that I've found that does exactly what I want. The review aggregates are the most inaccurate I've seen. Maybe having it upside-down as the default in the past caused the bad reviews. Otherwise there is not an app on the play store that does what this does. 5 stars all the way.
