Works great!

This app works great as a heart rate monitor. I am an anesthesiologist and have access to pulse oximeters at work. I compared the results from this simple heart rate monitor to the pulse oximeter at work and it was almost dead on. Although this one tends to drift a little bit up-and-down by one or two beats compared to a real deal pulse oximeter. So not as accurate but I was very impressed by the fact that the results from this free app were as precise as they were. So a nice app to quickly take a look at your heart rate.
