Testing 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.
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.
Doesn't do anything except waste space. This app is trash.
Simply The Worst
Nothing is worse than a charlatan wasting people's time with a bogus [app]
Super sensitive receiver. Excellent!
It is awful. DONT BUY
By Dropped Db
Doesn't seem to pick up anything below 73hz.
I don't like it.
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.
Excellent Frequency Counter〰
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.
