Needs to be updated!. Slow and inaccurate. Waste of $3.

Can't zoom in on amplitudes. Either I can't figure it out (most likely), or you can't zoom on the Y axis. I was trying to determine the frequency of the audible vibration my car was producing. The peak amplitudes just blend right in with the noise when it's zoomed all the way out. Also, sometimes the actual graph disappears. It will still show the frequency of the peaks, but the rest of the screen is black.

Basic Analyzer. Works as expected.

Very useful. Use it to check venue audio dynamics during sound checks.

Key feature broken. Cannot pinch to zoom in frequency domain as it states in FAQ. Needed this app to identify specific higher frequencies but the ones I want get overshadowed by low frequency noise and I can't zoom those out of window. Labeling the peaks by touching them would be nice rather than app only labeling overall maximums.

Goldilocks. Exactly what I was looking for. Just right.

Nice, simple.. Very east to use. It allows stretching/shrinking the frequency axis (for the linear scale only). It would be nice to have a way to freeze the spectrum to make some quantitative comparisons. Then a screen snapshot could preserve the results. Would also like to know just what kind of filtering is being used.

I like it. When I want to the frequency of a background tone on the radio, this works great. My wife bought some Tibet bowls. I wanted to know the resonant frequency for each bowl. This app worked great. Lots of applications. Now, only if it could fix the ringing in my ears!

Not good. Very low update rate and limiyed interface, definitely not worth paying for

Just the thing.... Intuitive, simple, powerful. Read the FAQ, which is the user guide/manual.

Perfect.. This is a very affordable app that lets you do incredibly useful things as a sound engineer. I run sound for our community theater and play in a country/rock cover band. I've used this in both settings to easily located and remove problem frequencies with a GEQ. Lots of options and easy to use. Life saver.

Useful as engineering tool. I'm a practicing electrical engineer and I wish I'd had this app when I took the DSP class in college. Straightforward control of FFT parameters makes it fun as an exploration tool. I'm using it to track down acoustic noise on voltage regulators.

Good intuitive competant product. As spectrum analyses go this is pretty good for an iPad !

Great for mobile frequency checking. Recommend this for novices and pros. Great for setting up a sound room or booth. Good Job!

This app is sold with false pretenses!. Buyer beware! This is listed under Spectrum Remote. I wanted to control our TV using my phone. This does not do that. I asked for a defund and was told NO!

works, but slowly.... iPhone 6s; This is a nice app that works - but the sample-rate is quite slow… or maybe the the screen update is slow. There is a peak hold feature that is quite unnecessary as it takes a large fraction of a second for the display to register a change. The display then persists for some time before decaying.

Very nice spectrum analyzer. Unlike many other spectrum apps, this one allows some configuration. You can select the window type, peak hold average, and number of spectral lines, among other things. You can't select a maximum frequency other than the highest possible (I guess because this would require a down sampler and digital filter), but since it lets you pick a very high number of spectral lines, you can window the results to get what you need and still have reasonable resolution. We use it for quick and dirty measurements when we don't want to set up the high dollar gear. For example, we recently used it to determine blade natural frequencies (or at least the first one since it radiated significant sound) for an axial compressor to select which should be adjusted to meet the spec. This saved the project many hundreds of dollars in setup time for each blade. We used our high tech gear to get the final data, but this app was great for the initial cuts. I'd give it five stars, but I'm saving the extra star for when they update to provide a linear vertical axis and perhaps more control over FFT parameters.

Spectrum at your finger tips. I monitor a bluegrass band with this app. Nice to know room characteristics for PA low & high freq. settings.

Accurate on iPad mini. Happy with this app. Frequency markers on peaks very handy. Checked against 500 and 600 Hz tones on WWV and both were within 0.1 Hz. Recommended.

My review. Great app that works as advertised. Successfully EQed my home stereo system which is set up in a problematic room with a high ceiling and many reflective surfaces. Running on an iPhone 6 plus.

Review. Very poor, not what I expected. Tried to get a refund. No luck.

Functional. Does exactly what it says on the box. Sometimes buggy (at least on iOS9). Zooming sometimes doesn't work. Resuming the app after switching to something else makes it not display frequency data. Not perfect, but more than acceptable.

Oops....white screen only....does not work on my iPad 1....ver.4.3.1...hmmmm.... Oops....white screen only....does not work on my iPad 1....ver.4.3.1...hmmmm....I hope it works on the iPhone 4!

Don't buy. This terrible app has a response time slower than the free spectrum analyzers available out there. Do not waste your money

Worthless. I am an audio engineer and thought this app may have some semi-useful purpose. However, it is total junk. There is zero accuracy to this app. Do not waste your money.

Been there, done that - good app!. Being an ex-submarine sonar man, I appreciate the application. Seems to function as designed. I'd like to see a "waterfall" display and a sliding cursor/zoom window which would make the app Awesome! Thanks and keep up the great work! Peter

Excellent tool. Great tool for analysis of audio sound.

Great app!. This is a great app! I use it all the time .... Especially to find troublesome hums, etc.

Excellent app for audio analysis. This works really well for audio analysis

Absolute Waste of Money. This app offers nothing that you could not get from a free spectrum analyzer app. In fact, you will find it more convenient to work with many of the free apps. This app has absolutely no features that could justify paying for it. All it does is doing a simple FFT. I want my money back, however it is too late - unfortunately! 😕

Simple to use, but full featured. I bought this app because I wanted to identify a mysterious high-pitched tone that was audible in my house. It worked great. The tone was clearly visible as a peak around 6400 Hz, and then I was able to confirm using a tone generator. I'm just a casual user, but the app presents a feature set that would appear to satisfy more serious users too. It also has a very no-nonsense interface, which is what I look for in an app.

Got noise?. Excellent tool for analyzing sound background noise, and data transmission modes. Features allow zooming in and out and peek hold.

stopped working after about 3 minutes. but hey, does anyone’s design actually work nowadays?

Some added features would be nice. Nice analyzer and responds well. However some features would be nice.i would like to see the ability to freeze a spectrum and possibly save it or have it emailed so it could be studied. Also, it would be nice to isolate portions of the spectrum to analyze it.

Great little SpecAn. This is a great app for showing the basics of FFT to physics students. It would be a nice touch to add the ability to manually place markers, but with care the auto-peaking markers work well enough. Not bad for a few measles bucks!

Works. Works fine on my iPhone 5S. Great, simple little monitoring app. I bought it for the markers, which helps me kill feedback.

Awesome. Last one you'll have to buy. Make an apple watch port please!!

Doesn’t work. Doesn’t work with iPhone XR. Looks like it has t been updated in years. Not worth any money

Simple. Good. More detailed grid, more better.

Great. Great App almost exactly what i was looking for! Great value. It works smoothly and easily. Minuses? Yes I wish it went to 40 kHz! While 20 covers the audio spectrum for most people, a few people (and most dogs) have hearing above that range. The instructions for selecting the filtering window need to be expanded. Other than those two minor whines, it is a great app

Spectrum a day saver. I use Spectrum regularly in my work with venue audio. It's great for Eq-ing the house and testing speakers and selecting mics. Easy to use with great results.

Needs averaging. Very useful, but it would be so much better if it could do a running average of the spectrums. This would help to pull signals out of the noise floor.

Tuning a Mbira. Great app for tuning non stringed device. Good to see overtones and other “noisy” peaks. Works exactly as described.

.. Great app, good value. Very helpful for an untrained ear to see what's going in inside the mixer.

Absolute Garbage!. Totally unusable. It is a fraud to say this is in anyway acceptable. When entering text you are unable to see it, the controls do not seem to function, very laggy. Absolute trash do not buy this.

Love it!. Very handy in recording studio.

Problems with newer iPhones. No way to exit on iPhones without a Home button

Meh. Slow responding app, not suitable to correctly monitor frequencies if you need to observe them in real time. Needs some more work to make it usable.

Ooops. Took a gamble with $3 and lost. Unless there are some hidden controls, this app does nothing useful.
