BioBreathing

Biofeedback breathing is a breath pacer that allows the user to keep count of Inhale and Exhale breathing cycles. The user can set the lengths of the Inhale and Exhale phases independently. One tone is used for the Inhale phase and another tone is used during the Exhale phase, allowing the user to use the app without having to look at it. Different tones can be selected for each phase

The lengths of each phase can be increased to a maximum of 10 seconds.
