## A–440 Reviews in United States

### **--- "Good for a while"
Stopped working, right in the middle of a church service when I needed it. Nice while it lasted.
-- Chilean Angry bird lover, 2023-03-06

### ***-- "Developer email fails"
Developer email fails. Therefore there is no support for this app.
-- OnlyMyRatings 72, 2022-11-24

### *---- "Not actually free"
Stop doing this people
-- cmcgeeman, 2021-05-25

### ***** "Finally a tuner for real musicians"
This app is exactly what I’ve been looking for! No ugly sustained tone; no superfluous pitch selection or—worse yet—insulting frequency measurement. Just an adjustable A4 with a well-measured decay. Love it!
-- puente de paja, 2020-01-09

### *---- "thumbs down"
Much better apps available for free. They should not charge money for such cheap app.
-- misharaj, 2019-03-22

### *---- "It’s bad"
It doesn’t work and needs to get a life
-- the critic of things, 2018-08-05

### *---- "Don't annoy me if I paid for your software"
I paid money for the app.  In return I'm harassed repeatedly to give a review.  If you want one here you go.
-- Unreal Yorik, 2017-07-29

### ***** "Simple effective tuning"
A simple tuning fork. 
A 440. 
If you know how to tune your instrument, this should be all you need.
-- Christ!, 2016-10-26

### *---- "Used this for years but now crashes"
Used this app for years with no problems on iPhone 4S but on new 6S with latest OS it crashes on launch. Have re-installed to no avail.
-- Will DC, 2016-03-21

### ****- "Mostly Works"
Freezes when you hit "unlock".
-- LiveJazzLives, 2015-09-20
