About Frequency Meter PRO
App Store
Frequency Meter PRO is a comprehensive tool for audio frequency diagnostics. Includes REAL TIME scanning of audio signal from internal or external microphone.
*** OUTPUT ***
Visualization is done on real like device that shows:
- Audio level
- Noise Level
- Frequency range
- Current frequency
- Frequency oscilloscope
- Spectrum analyzer
*** ACCURACY ***
Application is calibrated with real tone generator. Working range is around 15 - 22500 Hz, and accuracy around +/- 0.5 %.
*** NOISE LIMIT ***
You can easily set a limit that removes noise treshold with included trackbar.
*** RANGE SELECTION ***
Choose minimum and maximum frequency you want to scan.
*** EXPORT ***
You can export output chart to comma-separated file that you can later analyze with MS Excel or other table processor. Application shares document folder in iTunes.
*** SUPPORT***

Limited and inaccurate!
Oct 20, 2017 It does work as a frequency meter but is somewhat limited. It doesn’t work on frequencies below 150 HZ . I tested it on 150HZ then 120 HZ. It showed a harmonic of 120 HZ. 99 cents would have been a fair price. Especially since it appropriated the fluke meter style to elicit confidence and imply compared results.more -
Fantastic App
Mar 3, 2017 Used this app for my AP Physics lab, worked fantastically -
Science Project
Mar 17, 2013 My daughter and I used this frequency meter for a science project measuring the vibration frequency of guitar strings. At first it seemed that it didn't work at all (as mentioned in a previous review). However, I then realized that we were working in a frequency range that was very likely below the realistic frequency response of the internal iPad microphone (I'm guessing around 100 Hz). When we moved to a smaller string and at higher tensions, the frequency meter locked right in and gave very consistent and reliable results.more -

Nov 8, 2014 I got it for my speech. I had a stroke last year and lost my ability to speak now I'm very monotone I'm hoping this will help.

Disappointed
Mar 27, 2015 Seems to be inaccurate. Reads a constant 10 hz higher when trying to get an A440 tone from both a MIDI keyboard and an accordion both of which are tuned precisely to exactly 440 hz . Meter reads 430.33, unimpressed and regret not reading previous reviews before spending $3 on this appmore -
Don't waste your $2.99 like I did
Dec 6, 2016 This is a joke. I think it was designed by a 3rd grader. No features at all. I didn't read the reviews before I bought it and sure wish I would have. I never leave reviews but this time it's a must if that tells you anything.more -

What’s Groovy
2 problems that make me want my $2.99 back:
1) I can't analyze frequencies without recording a file.
2) The frequency meter actually just shows you which note (A/A#/B/etc.) you are closest to, not the actual frequency of the note you are playing.

What’s Subpar
I just need an app that accurately tells me the frequency of s tone played through a speaker. This one kind of does that, for the first note presented to it, but fails to change its output when the tone changes. It sort of works if I keep shutting it down and restarting it, but that’s not very convenient. Also, it would be nice to have some documentation as to what the controls are supposed to do and what the display is supposed to indicate.
