NOTE: Works best on iPhone 4/4S/5/5S/6/6S/7/7+ 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!

Customer Reviews

Great for reviewing heart rate. However rate is slightly different than my oxygen saturation meter.

I am a 76-year-old physician in relatively good health and take my pulse and oxygen saturation at least twice daily.
My calcium score was high and I may have had a silent heart attack according to my EKG years ago. I strongly recommend people read the "China Study" and "the spectrum by Dr. Ornish" They both suggest you can reverse cardiac disease!! Pritikin was a good example of reversing atherosclerosis.
I am more than 90% vegetarian and walk up to two hours every day. Although I was raised on a dairy farm I avoid dairy products as much as possible because of the possibility "they can turn on cancer genes" as well as promote atherosclerosis.

Great - saved my life once

I was feeling OK, but I could tell that there was just something off somewhere, so I sat down, and I started this app and checked my pulse rate. I was shocked to see that my pulse rate was 190. So I dialed 911, and they RUSHED me to the hospital, where I had emergency surgery to relieve the pressure around my heart. I routinely use this and check it against my pulse meter, and they're always within one or two beats of each other.

But if it hadn't been for this app, which was the only thing I had to check my pulse at the time, I would be dead today, two years later.

Best is getting better!

Get it. Use it. It's accurate. Gives you an easily understood history of your pulse readings a child could understand. And it's pretty : )

I continue to use this app with great satisfaction and appreciation. Periodically I test it against taking a wrist pulse. It's always spot on. Convenient, easy enough for a tot to use, and accurate.

Of the many health apps I've tried over the past few years, there are only a handful I use. This is one. It's accurate to a fault and it keeps and shows the history of readings in a novel and very comprehensible way.
