Accurate for me! (iPhone 4) – Heart Rate - Free Review

I just tried this for a minute but found it to be very accurate by holding one finger over the camera like it says and taking my real pulse at my neck with my other hand. The top green dot lit up every time I felt a beat and when it got off slightly, it would quickly fix itself to be right back on. It worked for me!
