Breathe On is a portable breathing exercise game that runs on batteries and connects to a smart device. It has 15 games of varying difficulty levels that encourage users to breathe in a way that improves their breathing capacity. While breathing is a natural process, athletes know that training on how to breathe can improve their performance. Those with asthma, lung damage, or chronic obstructive pulmonary disease may have compromised breathing leading to poor health. Smoking can also restrict oxygen exchange in the lungs. Deep breathing can reduce stress, calm the mind, manage anger and improve health. Breathe On's game-based approach makes it easier for people to stay motivated and maintain a regular exercise routine. By breathing into the mouthpiece, users activate movements in the game that exercise their lung muscles. The scores and progress reports provide feedback to motivate users to improve and reach higher levels. Additionally, breathing exercises can also burn calories.
