NOTE: Works best on iPhone 4/4S/5/5S/6/6S because it has flash. On iPhone 3GS and iPod touch the app has to be used in good lighting.

NOTE: Make sure that your fingertip completely covers the camera lens. Press gently, since pressing too hard reduces blood flow in your finger and it's harder to get a result. Make sure that your fingers are not cold. This app is for recreational and fitness use only!

Used to be better

I have an electrical malfunction of my heart. My heart will speed up to over 300 beats a minute without warning. Sometimes, the only way to stop it is to call 911 and get help. I have used this app for years. As soon as an episode starts, I grab my iPhone and keep track. If it does not slow down within a 10 minute period I call for help.
Recently, the app changed. Now, it takes more steps to start recording. Then, there is another page that pops up wanting to know what you were doing when you checked your heart rate. I have trouble quickly getting back to monitoring my heart again. I find it very frustrating now, especially when I am in a stressful situation already.
The monitor used to be way easier and less burdensome. Wish I had the old app. For me, it was way better and was a huge help. This app was such a convenience for me for a long time.

Great and ingenious!

I been riding my bike a lot and using my elliptical, I've been reading a lot about heart monitors, as a watch, or with a chest strap, they are expensive and I would prefer not to wear a chests trap while doing anything actually, when I stumble on this app, I was skeptical of course but as I read how it works I found it to be so ingenious! And used right is very accurate! I wish it did not have the ads that interrupt so much, and I wish they had an in app purchase to get read of them one that wasn't a subscription, but as it is the app works well enough for me, and it adds to the bag of tricks that my phone performs, I recommend this app!

A Must Have Health APP

I've tried all of the free heart pulse monitoring apps and this is by far the best. It is accurate every time. It even shows arrhythmia on the charting. I have a large range in my pulse ranging from 39 beats per minute to 180 when vigorously exercising and it always counts and charts it in an easy to read graphic interface. I like the continuos read option so I can get a true resting pulse over several minutes. I use this app while biking and any time I'm curious about my pulse. It confirms episodes of arrhythmia visually and with an audible beep. It allows me to show my pulse pattern to my doctor.
