Every now and again, a little app comes along that impresses you and serves a real purpose.
Today, I found Instant Heart Rate in the Google market place which promised to tell me my heart rate by simply putting my finger over the camera lens. I was intrigued, so I downloaded it.
I didn't expect much to be honest. I didn't understand how it works, but, it was accurate. It got my heart rate spot on.
All you do is put your index finger over the camera lens for 10 seconds and up pops your heart beat, very clever indeed!
