1. Counts when the input rises or falls past a set level and converts into into frequency or a time period. FOR INDICATION ONLY.
2. If you just want to know the frequency of a sound with harmonics (e. g. mucial instrument), a FFT based app such as keuwlsofts spectrum analyser or guitar tuner (both free) will be better.
3. Display of triggered event count and frequency or time period.
4. This app can provide more accurate frequency measurement for single frequency input signals.
5. Frequency counter based on the microphone input.
6. Graph of input signal, 2. 5 ms/div up to 640 ms/div.
7. Results depend on your device and its hardware.
8. Set a noise level so new event is not triggered until the signal has first passed this level.
1. The gadget is anti repellent insects , and since it works on low frequency i couldn't know if the device is working or not so i tried few apps and discovered this app and the results was accurate.I tested this app with pure tones and it works perfectly.
2. i tested this on a 1000 hz and 500 hz audio and the frequency that was shown in the app was correct.The reading i get is accurate , as i wanted to test a gadget i download this app.
3. BTW, when it says "contains ads", it means a tiny box at the top of the screen that you'll hardly ever noticetop notch app, while it's not as accurate as regular frequency counter, it still does it job well.
4. Look for pure tones with this app.Super accurate, I measured a 0.1 Hz difference at 360Hz.
5. It has been accurate for reporting pure tones.
6. I have compared the readings simultaneously with an oscilloscope and the frequency difference is only about 100-500 Hz.🌟 Great application just what I was looking for.
7. Dont go buy the titles on you tube that suggest 528 hz most of them are not even close to accurate.
8. Frequencies are accurate.
9. The screen is easy to read, simple to understand.This app does exactly what it tells.
10. For those of us who are using frequencies for meditation and healing, use this App to test false frequencies.
11. You have to push all the buttons a few times to figute out whats going on but it has good features.
