About this app

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.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
