Dave's Heart Rate Monitor allows a user to easily measure their heart rate by placing a finger on the Camera.
The app uses two different techniques to extract heart rate data form the green channel of the camera.
The app allows a user to save the green colour channel data to a text file in the Files space of the app.
There is no advertising.
For best results keep finger and phone still and wait for the colour trace to settle.
The app does not communicate with the internet, all data is private.
