Want to know the precise frequency of a signal or the visual shape of a signal? Then you’ve come to the right app. Use your device’s microphone to see waveform, frequency and even the musical note of a signal in real time with Frequency Counter.
Accurate!
I needed a frequency counter to measure the resonant frequency of wine glasses for a science project. Part of our experiment is to break them by playing the resonant frequency back at high amplitude. I tried some other apps but they rounded the frequency and were pretty inaccurate. This one is extremely accurate. Mind you this is all it does (plus displaying a waveform), but it does it well, so five stars.
United StatesHerts measrement
Does not do what it says it will. It very rarely gives a measurement in hertz. Only shows a useless and unlabeled graph.
United StatesTesting my home made wind chimes
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.
United StatesWorthless
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.
United StatesWorthless
Doesn't do anything except waste space. This app is trash.
