    Simultaneously display multiple Heart Rate Monitor (HRM) belts values using the ANT+ protocol. Useful for Cardio-Fitness, Spinning class and Gym fitness workouts, to easily display and control the training activity of up to 8 persons. HR reading of each trainee is displayed as relative % and absolute value.

    If supported by your device, all readings can be output to TV via HDMI

    The training instructor can at once see all the HR values, and suggest better and personalized training activities accordingly.

    This is a DEMO, with only up to 2 simultaneous channels, with limited functionalities and without registration of channel settings (such as Device ID, Name, Age and gender, useful to determine the relative % of Heart Rate). Use this version only to check your Hardware works.

    Full version is available, with up to 8 channels, settings storage (association of channel to a specific belt) and record to file with data available in CSV format for email/sharing. Experimental 18 HRM belts is available now!!! Please go to the full version download page.

    You MUST have an Android Device with ANT embedded chip and install the Dynastream ANT+ Service available at:

    See the link also for ANT+ native support devices!! See my working setup in the screenshots!

    As alternative, you should plug a ANT+ compatible USB key to you Android device using an USB adapter, and in addition install also the USB Service from Dynastream available at:

    All HRM belts used MUST be compatible with ANT+ fitness and endorse the ANT logo. More info at

    A typical setup consists of a KM802 Android TV pen, with an ANT+ USB pen supporting up to 8 HRM ANT+ belts. The MK802 has HDMI output to display data on a large TV (see the screenshot and video: a picture of the flat TV displaying live data via HDMI) in the Gym workout room.

    For problems installing the USB support service see:
