## Key Detect Reviews in United States

### *---- "Not accurate - waste of time."
Title says it all.
-- MusicForMySoul, 2022-08-08

### ***-- "Not working"
I’ve had this app for a good year or 2 and it all of a sudden stopped working today. It won’t pick up any sound and the mic is enabled.
-- DraeToo200, 2021-05-29

### ***-- "Works just fine"
It took some time to figure out the way the app runs, but it’s fairly easy to use and pretty accurate for musical purposes. Tbh, it’s suitable to use and have if you don’t have mixed in key.
-- GEE5IVE, 2021-03-03

### **--- "Not accurate"
I analyze all of my music with Mixed In Key and tested Mixvibes ageist their analysis (which is the best in the industry). Mixvibes was close, it was plus or minus 1 step consistently. If this is the only thing you use for key detection it will probably work fine, but it was disappointing in contrast with real key detection that relies on the actual files instead of the mic.
-- miker619, 2020-10-22

### ***** "This actually works"
I took the reviews with a grain of salt bought for myself anyway and it seems to work just fine.
-- gxdthh775, 2020-09-27

### *---- "Bad interface."
I didn’t think I was using the app correctly. 
The start button only changes color. It is not clear when the device is listening and analyzing the music. 

I can’t tell if the display is updated or stuck in a setting mode. 
I don’t trust this app and regret buying it.  

I couldn’t find instructions. The description only promises that it is easy. 

Too bad it is not as described. It would have been nice to have this app working.
-- KevinPingers, 2020-09-04

### *---- "Terrible"
Does not work at all.... do not pay for this. I want a refund ASAP.
-- Brye0000001, 2020-01-19

### *---- "Complete waste of money."
Cannot use to detect song key. Useless.
-- fiddleplay, 2019-11-14

### *---- "SAVE YOUR MONEY"
This is actually trash.
-- AvtheSav, 2019-05-29

### *---- "Don’t buy"
Wouldn’t recommend, didn’t work good at all.
