Heart rate app

This is my averaged heart rate over the day from the data of 67 days.
So you can see pretty clearly when I am sleeping from eleven to about seven in the morning.
Then I am cycling to work, where you can see the biggest peak.

The heart rate data was captured with an heart rate monitor, which sends the heart rate to my phone and this data is recorded by my app.

After the data gets collected on the phone it is sent to my homepage, where you can see my actual pulse.
