Awesome!

This is a great App for an exercise in remembering to take deep inhales and exhales. It is a starting point. I have read some of the reviews and this is not about yoga or any other breathing and is a good first step to begin to take diaphramic breathes. Most people only inhale in a shallow way and never truly expel the air in their lungs. You have to be cautious at first, if you are not used to taking deep breathes. You will be light headed and a bit dizzy because your body is not used to receiving that much oxygen unless of course you already do yoga, or perhaps are professionally trained as a signer.
