Breathing Pattern is a free iPhone app developed by Andrew Hodgson in the Lifestyle category, specifically under Health & Fitness. The app aims to assist users in improving their breathing patterns through guided exercises. Users can customize the duration and speed of the exercises to suit their needs.

In addition to the breathing exercises, the app offers a questionnaire to help users become more aware of their breathing patterns. It also provides information on achieving 'Good Technique' for efficient air movement in and out of the chest using the correct muscles. By enhancing lung effectiveness and balancing the body's physiology, users can experience improved well-being.
