### 5/5 — A-440

*2011-01-02, version 1.0*

Does exactly what it says it does. I prefer the "A" tone due to the fact it's easier to hear tuning my acoustic bass around a crowd. Straight forward no BS app! 5 stars here!

### 5/5 — ........

*2010-10-24, version 0*

### 1/5 — Not actually free

*2021-05-25, version 2.5.5*

Stop doing this people

### 1/5 — thumbs down

*2019-03-22, version 2.1*

Much better apps available for free. They should not charge money for such cheap app.

### 1/5 — It’s bad

*2018-08-05, version 2.1*

It doesn’t work and needs to get a life

### 1/5 — Don't annoy me if I paid for your software

*2017-07-29, version 2.1*

I paid money for the app.  In return I'm harassed repeatedly to give a review.  If you want one here you go.

### 1/5 — Used this for years but now crashes

*2016-03-21, version 1.0*

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.

### 1/5 — Doesn't work

*2015-11-01, version 1.0*

Crashes on launch on iOS9.

### 2/5 — Good for a while

*2023-03-06, version 2.5.7*

Stopped working, right in the middle of a church service when I needed it. Nice while it lasted.

### 3/5 — Developer email fails

*2022-11-24, version 2.5.5*

Developer email fails. Therefore there is no support for this app.

### 4/5 — Mostly Works

*2015-09-20, version 1.0*

Freezes when you hit "unlock".

### 4/5 — Indeed the best plain and simple tuning fork but->

*2011-12-27*

it causes the music player to stop, sometimes I'm using the work to determine a key of the currently playing song/chord.

Would be great to have it advanced so that it doesn't stop the music.

Thanks anyway.

*2026-04-16, version 2.5.12*

Works quite well

### 5/5 — The Lost Art Of Tuning By Ear

*2023-03-23*

Using tuner pedals for decades severely impaired my ability to tune by ear. But this great little app on my phone has brought it back up to snuff. Plus I now always have tuner in my pocket!

**Developer response:** Hallo VWorks user,
thanks for your feedback. It's great to hear that another pair of ears have been happily returned to service.

### 5/5 — Finally a tuner for real musicians

*2020-01-09, version 2.2*

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!

### 5/5 — Simple effective tuning

*2016-10-26, version 2.0*

A simple tuning fork. 
A 440. 
If you know how to tune your instrument, this should be all you need.

### 5/5 — Tuner

*2012-08-21, version 1.0*

VERY useful. VERY easy to use.

### 5/5 — This app saved me today.

*2012-08-18, version 1.0*

I'm a professional piano tuner.  Today I forgot my tuning fork.  I got out my iphone searched for A440 and downloaded this app.  It worked perfectly and allowed me to do the tuning work.

### 5/5 — Fantastic!!

*2012-02-07, version 1.0*

Simple and brilliant! Thanks :)

### 5/5 — Good

*2011-08-08, version 1.0*

All you need really. None of this fancy business. Thanks!

### 5/5 — Awsome

*2011-06-24, version 1.0*

Nothing complicated and a perfect a.

### 5/5 — Satisfied

*2011-01-21*

It's an A, and that's all I need.
