Heart Beat Monitor

This application allows you to check your heart beat.
##HOW IT WORKS##
-----------------------------------
-This application uses camera of your android device as light detecting resistor or a photodiode.
-In this flash light is working as light emitting diode.
-Combination of both works as heartbeat monitor.
-It works by calculating level of oxygenated hemoglobin (hemoglobin is having oxygen in it) in blood.
-When large number of oxygenated hemoglobin in blood, It results in higher absorption of light.
-When Heart pumps blood that time level of oxy hemoglobin is high which reduces until heart pump again.
##USAGE GUIDE##
--------------------------------
-Just place your index finger on back camera near flash light(will act as light source)
-Don't press finger hard on camera, it results in harder for blood flow via finger, which makes difficult in reading pulse.
Rest of thing app will do.
