FreqCounter App Reviews

.99 cent in app purchase well worth it if your serious about using this as a tool. Keep the updates coming guys!

Would like to see more options such as max and min history as well as max updating. Average for power and more. Does what it says though!!!

I have been using this app to show my physics students how to measure frequency and use the data to calculate wavelengths and velocities. The readings are spot on with our tuning forks. If youre a science teacher, particularly physics, this is a must have.

The app works great, but it freezes when I try to purchase the FFT plugin. There is no way to purchase the plugin in the App Store either.

Excellent app! Does exactly what it is supposed to do, and checking it against various online tone generators, does it very accurately. I use it to check wind chimes. Thanks!

It is really powerful and useful!

I use this app in my classroom for labs and sound demonstrations. It works well and has lots of functions I use. Slide zoom needs work though. Seems to have a mind of its own. Overall - good app that does what it says.

The latest update improved the use of this app immensely It would be nice to have a user gain adjustment for sensitivity

This is a great app; accurate, easy to use, and very useful.

Not at all accurate. Overloads easily. Unfortunately, I havent found anything better in the App Store.

I frequently (no pun intended) use this app to show my grandkids how the piano and bell notes work. It works very well. I would like to have a gain adjustment since the waveforms often exceed the display height so you cant see the shape of the waveform. It would be great if you could set "keep waveform within display" that adjusted the gain to keep the waveform peaks on the display. As it dies out, it could get smaller than full scale.

I needed something that could measure the frequency of sound waves for a Physics lab I was doing, and this was seemingly the only app that would give me an exact value, so I paid the $3... This was a mistake. Despite the reviews that say otherwise, THIS APP IS EXTREMELY INACCURATE! I used a 512 Hz tuning fork to test it, and it told me that the frequency was 745 Hz... I would expect a margin of error from a phone app but this is a little excessive... I ended up downloading a guitar tuning app that gave me an exact frequency value, and was accurate to within 3-4 Hz. Whatever you do, DO NOT waste your money.
