About Whistle Blow

Blow Whistle is a beautifully designed application which allows you to blow into your device in order to create the sound of a whistle.

No need to carry a real whistle when you have one on your iPhone, iPad or iTouch. You can use it to annoy your friends, parents and co-workers, or just use it as a useful whistle for whatever purpose you have in mind. You can adjust the sensitivity of the whistle for noisy or quiet environments.

You can also activate the whistle by shaking or tapping your device.
