A Heart Rate Monitor application focused on finding the right 'pace' of an individual or even a group of people exercising together.

Once the application is connected to a Heart Rate Sensor (Polar, Garmin, etc.), the app discovers other users nearby (10m). It will notify the whole group if the pace, and therefore the current heart rate of certain participants, is too high.

This application can be used as a companion with other activity-tracking apps like "Adidas Running" or "Strava". Those apps however will not be able to detect the external heart rate sensor if it was already connected to the 'Pacemaker App'. It is recommended to first open such an activity-tracking app, connect to the sensor, then launch 'Pacemaker'.
