HRV tracker 1.1 Description:
HRV tracker is a free and open-source utility designed to log R-R intervals from an ANT-compatible heart rate strap. HRV tracker can receive data from either a serial-port ANT receiver device (e.g.: the SparkFun ANT USB stick) or the ANT USB receiver stick that ships with many ANT-compatible heart rate monitors and GPS units (e.g.: Garmin ForeRunner series). HRV tracker is cross-platform and it works on Mac OS X and Windows. Binaries for the Windows platform are available on the project's homepage.
