## FFT Plot Reviews in United States

### *---- "Disappointing"
Scale ranges can’t be customized and cannot see low frequencies below 20Hz and DC value.  If this were fairly clarified, which it isn’t, I would not have purchased this as it is really useless when those features are what you need.
-- Omega Yeti, 2024-03-22

### ***** "Great job"
This app does exactly what it claims to and looks great. I’ll be using it in the classroom soon to demonstrate concepts like “narrow sound frequency band”. Thanks!
-- FlexAeldman, 2020-08-23

### ***** "Review From an EE in Signal Processing: Excellent!"
I’m a BSEE (University of Washington, 1995) with experience and a bunch of patents in signal processing. This app is an outstanding tool for understanding the spectral content of an audio signal. It was clearly designed by someone with some expertise in the field, and it’s a joy to use.
-- MutatingReplicator, 2020-07-31

### ***** "Absolutely fabulous"
Works perfectly. My only wish would be to also look at the waveform in the time domain. I use this app for testing new speakers. You will not be disappointed.
-- steve kirsch, 2020-07-29

### ****- "Great app, needs a way to export data"
I greatly enjoy how feature full and yet simple this app is. It runs great and seems quite accurate. One thing I think is dearly missing is a way to export the signals measured to a file (like csv). Taking pictures is great for qualitative comparison but this tool would be way more valuable if it could be quantitative.
-- Dasjing, 2019-08-20

### ***** "Favorite fee app"
As a studio engineer who has to run live sound a few times a year, this app saves me a lot of trouble. I can ring out mics in a heartbeat and solve problems more quickly on the fly. No more sweeping for the exact frequency to notch, or for where to center the de-esser! It’s especially handy on an iPad with its larger display.
-- Elvenmimstrel, 2018-11-20

### ***** "Performant and accurate."
Fantastic! Apps like this are the reason we don’t need to buy a stupidly overpriced bespoke piece of gear for every little niche... unless we want to! Keep up the great work!
-- Nerds Limited®, 2018-11-01

### ***** "Great app"
The averaging function works really well.  It would be nice if I could figure out how to use an accelerometer with it
-- unenigma, 2018-05-24

### ***** "Great respect for the app developers"
I use it to show my kids what music looks like in the frequency spectrum.  Given how much time is required to learn and program an FFT analyzer, I am glad to support the developers efforts.
-- Retina.doc, 2018-05-05

### ***** "Very nice"
Very nice app. It hasn’t been updated in quite a long time but it works just fine in iOS 11. I’d like to see an update with more robust features (hi developers) maybe a spectrum analyzer too or more info on the frequency graph etc. 
But as it stands it works very well.
