Does not do what it says it will It very rarely gives a measurement in hertz Only shows a useless and unlabeled graph     Herts measrement Don't waste my money

I bought this to measure the frequency of the tones from a five tube wind chime I made My iPhone is a 5C The scope display is of little use but the frequency shown below the scope is stable and spot on My design was tp produce and E note at 659 Hz this app measured it at 658 Hz damned good I found no other app that offered the measurement of an arbitrary frequency ANd this was only 0 99 I wonder if the other reviewers that faulted this app have a defective mic                     Testing my home made wind chimes Ron_Calif

Apple needs to add a negative star to better rate apps like this Not only does the app itself do nothing of value the developers instructions help mode is useless This shows how little effort and thought went into development     Worthless Fredmigillicutty

Doesn t do anything except waste space This app is trash     Worthless Fredmigillicutty

Nothing is worse than a charlatan wasting people s time with a bogus app     Simply The Worst Jackson_Jefferson

Super sensitive receiver Excellent                 Great app Danmusic1357

It is awful DONT BUY     Don t buy MARCH9801

Doesn t seem to pick up anything below 73hz         Poor description Dropped Db

I bought this app for my physics exam project I didn t know that it didn t display the hz We had to buy another app because this one didn t have the hz Waste of time and money     I don t like it JessicaMurawski

Easy to use and accurate plus a well designed display user interface Looks like using a classic oscilloscope but auto ranging Under the tube is where the alpha numeric frequency counter note scale are displayed                     Excellent Frequency Counter ad6xj

Needs to display the Hz             Interesting but golden cindy

Will only display frequency of clean pure tones and even that is hit or miss Being in an environment where that is possible is often very impractical     Poor App Justin E.

Seems the detect my pianos frequencies from E2 to E6 Would like more notes but good in that range Frequencies don t seem to exactly match my strobe tuner app or 1 2 cents Still looking for greater range and the ability to calibrate if it s off a bit                 Good from e2 to e6 Mcdtracy

What a total piece of crap application I wanted to be able to test frequencies tapping watermelons This thing won t even test a frequency of a simple whistled note What a waste of my money     Huh Disatisfied54

No numbers no measurement of background noise frequency no instructions of no value I waster the purchase price     Worthless iMan222

Although I seldom review an App I was so intrigued by the Frequency Counter Pro that I had to comment I tested this counter on an iPhone 4 as well as the newest iPad using iOS6 I found the displayed frequency to be quite accurate between approximately 75 and 2000 Hz Beyond 2kHz the display began to show errors but interestingly these were harmonically related to the test frequencies For example a 4000 Hz tone may display as 2000 or a 2800 Hz test tone may display 400 Hz 2800 being the seventh harmonic of 400 perhaps Maybe Cat Eater the developer can explain this more thoroughly Other than this quirk the graphics are clear and simple with a retro oscilloscope look I am however puzzled by the red indicator lamp below the display It looks like the power on off button on an Apple computer but does nothing if you touch that area of the screen The only touch screen user interface is to control the amplitude of the displayed signal For example if you we re sampling a quiet audio signal you would set the amplitude to the high mode while low mode may be best for loud or noisy environments My only wish besides showing actual frequency up to perhaps 10 kHz would be a display hold button Bottom line is that the App is interesting to play with and would be useful in several areas where you need to identify an audio tone or musical note Cliff K                 Frequency Counter Dog boy 4

Does exactly what it should Shows hertz and note of any sound Perfect for my daughters science project                     Great app Hiporthodoc

My first review it works great                     Nice work Vitanaut

Tried to check this against several accurate tuning forks and instruments Not worth the buck I paid for it     complete garbage Another xzwytr

No numbers just pattern     Displeased no numbers Fiskerdoo

Very simple downloaded it for an emergency violin tuning and it worked flawlessly thanks                     Great tuning app HCSGuy

I ve only had this app for a minute or so now but it works well It is a bit odd in my opinion how the frequency only shows up when a tone is being played Backround noise will not show a frequency This makes sense of course but I wish it said something like Frequency instead of merely a blank spot where the frequency goes I was very pleased to find that it actually said the note name in addition to the frequency like A or whatever I have yet to test it with a piano but with whistling notes it appeared to respond rather well All things considered an excellent app                 Rather pleased This Name Is Now Taken
