## Frequency Meter PRO Reviews in United States

### **--- "Not very good"
I just need an app that accurately tells me the frequency of s tone played through a speaker. This one kind of does that, for the first note presented to it, but fails to change its output when the tone changes. It sort of works if I keep shutting it down and restarting it, but that’s not very convenient. Also, it would be nice to have some documentation as to what the controls are supposed to do and what the display is supposed to indicate.
-- TMD913, 2019-07-25

### *---- "DOES NOT WORK"
DO NOT BUY THIS APP! I was trying to determine if the frequency on my keyboard was accurate (I can change the frequency on my keyboard). I’ve done this in the past with other frequency detectors. Even though you can actually HEAR the difference, this app does not register this change. For instance at A=440, the app says 441.39. When my instrument is tuned to A=300, this app says 441.39. Only when I tune to A=190 it changed to 417. So absolutely useless.
-- rory0110, 2019-07-08

### *---- "Useless"
Cannot get repeatable date using a tuning fork. Do not purchase!
-- Macdyver60, 2018-12-16

### *---- "Crap"
Trying to use it as a pianotuner it is way off in the meqsurements !!!
-- sindrimar, 2018-08-23

### *---- "DO...NO.....BUY......J...U...N...K..."
useless
-- nothanxfgfhfbfhfhvhv, 2018-04-18

### *---- "Worst purchase on the planet"
Does not work
-- ZCakeGaming, 2018-02-25

### *---- "Absolute piece of garbage"
No guidance on how to get it to work. Doesn’t deserve any form of rating.
-- laraidh Mordhun, 2018-02-20

### *---- "Terrible"
It does not display accurate measurements.
-- Jocko4, 2018-01-19

### *---- "Useless"
I wish I read the reviews before I bought this. My own stupidity.
-- KimberlyHoffman, 2017-11-21

### ***-- "Limited and inaccurate!"
It does work as a frequency meter but is somewhat limited. It doesn’t work on frequencies below 150 HZ . I tested it on 150HZ then 120 HZ. It showed a harmonic of 120  HZ. 
99 cents would have been a fair price. Especially since it appropriated the fluke meter style to elicit confidence and imply compared results.
-- Jmikej, 2017-10-20

### ***** "Fantastic App"
Used this app for my AP Physics lab, worked fantastically
-- Joshakoqgwush1936, 2017-03-03

### *---- "Don&#039;t waste your $2.99 like I did"
This is a joke. I think it was designed by a 3rd grader. No features at all. I didn&#039;t read the reviews before I bought it and sure wish I would have. I never leave reviews but this time it&#039;s a must if that tells you anything.
-- Key Source, 2016-12-06

### *---- "Completely inaccurate"
Fancy looking junk
-- VOLTAGExDT, 2016-05-10

### **--- "Disappointed"
Seems to be inaccurate.  Reads a constant 10 hz higher when trying to get an A440 tone from both a MIDI keyboard and an accordion both of which are tuned precisely to exactly 440 hz . Meter reads 430.33, unimpressed and regret not reading previous reviews before spending $3 on this app
-- Papa Chris, 2015-03-27

### *---- "Crashes on open!!!!"
This does not work in the current version of iOS!  Every time I press the go button it crashes!
-- karldenton, 2015-03-16

### *---- "Junk"
No instructions are provided on how to use, making this $2.99 worth of garbage on my iPad.
-- BigTuna842, 2015-03-02

### *---- "Not accurate!!"
Don&#039;t get this. I just played 1k to this app. It is not accurate!!
-- Eminy55, 2015-02-20

### ***-- "Only shows certain frequencies"
2 problems that make me want my $2.99 back:
1) I can&#039;t analyze frequencies without recording a file. 
2) The frequency meter actually just shows you which note (A/A#/B/etc.) you are closest to, not the actual frequency of the note you are playing.
-- p!kupthepieces, 2015-02-17

### *---- "Piece of crap"
Does not work. Just a piece of &quot;art work.&quot; Useless
-- jmpoth, 2014-11-22

### *---- "Crashes"
Crashes ever since the update. Cant use it anymore
-- maxiblobataxi, 2014-11-19
