The Fairhammer App is used in conjunction with GroovTube breathing exerciser hardware, as an aid to breathing exercises.

The GroovTube hardware unit is essentially a MIDI device which has been developed to output MIDI as a function of the User's breathing/airflow.

The Fairhammer App detects breathing strength, speed and duration and uses these parameters to move "mercury" toward the top of a thermometer-style graphic.

Users may sign in and use the App regularly, and the App can be used to show all historical User/Session data, providing a useful tool for therapists to monitor progress.
