Fairhammer is back with the Anniversary edition. Fairhammer is used in conjunction with GroovTube breathing exerciser hardware.
The GroovTube hardware unit is essentially a MIDI device which has been developed to output MIDI as a function of the users 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 recall all historical user/session data.
