Great app, above average in accuracy

Nice app, one I've been using for quite some time now, probably close to a year if not a year. In my last visit to my primary care at the VA a couple weeks ago I asked if we could check the accuracy against their calibrated devices. This came in within a point or two if being dead on. We did the test 3 times and averaged it to come out with our results.
My triage nurse was so impressed that she downloaded the app on her phone as well. With checking the accuracy of this app I was surprised at how accurate this app really is. So there ya go, this has been checked against calibrated medical devices and this app comes in very, very close. So no worries you can use this app and not worry about how accurate it really is!

All around awesome

I found out in June/July of last year that I was tachycardic, so I downloaded this app to keep track of my heart rate as we started new medicine. One night I was having chest pain and a hard time breathing and went to the doctor the next morning. I sent a screen shot of the EKG the app gives to a friend who is a nurse and he said I looked like I was in VFib. When I showed my doctor the strip, she immediately hospitalized me and my EKGs showed I have chronic VTach. This app in a sense saved my life, because without it I would have just continued on and my doctor said I could have gone into cardiac arrest or stroked out.

Very accurate

For someone like me that has a heart disease history, this application can be a life saver.

I was driving out of town and started feeling very tired and weak. Tried checking my pulse, and it felt very slow, so I figured I wasn't doing it right. Did a search on the Apple Store and this app came up. Downloaded, and tested myself. It was showing my heart rate at 30 bpm. I knew that wasn't right, so I drove to the nearest ER, and in fact, my heart rate was 30. Spend the night in the hospital after they gave me s medication to bring my heart rate back to normal. Told the ER Doctor what I did, and he said it probably saved my life.
