iHeartRate allows your apple watch to send and stores your beats per minute in to a database. The web application will then grab the heart rate information from the database and display it in a table in a graph. This way you can have more interaction with the information of the apple watch.
Your Apple Watch will start a workout as an out door walk in order to read your heart rate more frequently
Your Apple Watch will send the heart rate data through secure channels in order to store the informaiton on our servers.
From our servers the iHeartRate website will be able to display the information to you and will give you an interactive dashbaord.
