Description
Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period. FOR INDICATION ONLY. Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. musicial instrument), a FFT based app such as keuwlsofts spectrum analyser or guitar tuner will be better. This app can provide more accurate frequency measurement for single frequency input signals. Features include:
Display of triggered event count and frequency or time period. Graph of input signal, 2.5 ms/div up to 640 ms/div. Gate time of 0.1s, 1s, 10s or 100s. Gain from x1 to x1000. Trigger on rise or fall. AC or DC coupling. Set a noise level so new event is not triggered until the signal has first passed this level.
More details can be found on the website.
Recent changes: v1.19 Updated to use newer code methods to better target and run reliably on newer devices.

It definitely works. I got a gadget and had to test it somehow and when I turn it on the app detects the frequency immediately.

This app is perfect. Frequencies are accurate. For those of us who are using frequencies for meditation and healing, use this App to test false frequencies. It's helped me a lot. BTW, when it says "contains ads", it means a tiny box at the top of the screen that you'll hardly ever notice
★★★★★
I tested this app with pure tones and it works perfectly. Don't go buy the titles on YouTube that suggest 528 hz most of them are not even close to accurate. Look for pure tones with this app.
★★☆☆☆
Disappointed. Maybe it's my phone (Moto power g) or maybe it's me (lol). No matter which button I chose the graph didn't change. On the plus side, the ads are not intrusive.

Another dumb dog app it receives from the microphone and the g.u.I outlays the graph in the form of a decibel wave chart since most phones have no hardware on board that can measure electro magnetic emittance and hense why this app is a hilarious attempt of a waste of time by our security employees to send poor people down the app rabbit hole
