### 1/5 — Buhnda

*2022-12-01*

The app is straight trash. Just bad. On da guys

### 2/5 — for outside

*2017-12-04*

Not loud enough

### 1/5 — Doesn't work properly

*2015-03-31*

I purchased this app for my iPhone 6 Plus to help a young child do the HPVT. Every little sound in the room made the whistle go off. Blowing, however, did not.

### 2/5 — Basic

*2014-05-20*

No animation on the whistle and it only has one pitch. You can't blow harder or softer.

### 2/5 — Control whistle control

*2013-11-09*

To be a five-star app if I can control how many blows of the whistle there were or the decibel loudness of it aside from just the volume but you cannot control how many blasts is for whistle blasts no matter what and I just want one

### 1/5 — Crap!

*2013-07-20*

Whistle starts and then won't stop no matter how many times you hit the silence button.  I imagine that was meant as a joke??? Why is it no one can just make a simple app that will allow you to push a button and make a whistle sound that stops when you release the screen button??!!!

### 3/5 — It ok

*2013-03-15*

It's not the best thing on the earth but don't waste your money

### 3/5 — Just ok...

*2012-08-29*

This app would be great if you had the option to turn off the "blow" choice as well... Just holding the phone caused it to constantly whistle, which wasn't helpful when using it to start a PE race! Even with the sensitivity bar, it was either all or nothing.

### 3/5 — Not very loud

*2012-05-13*

Works fine but wish it would be WAY louder. Didn't help outdoors

### 1/5 — Annoying

*2012-03-18*

This app is just an annoying sound maker.
