Surprisingly accurate

I downloaded this HR monitor to track myself before and after my bike rides to monitor my progress. I noticed that my resting heart rate was in the low 50’s and that it was a little irregular. I figured that it was a flaw in a monitor that uses a phone app and it’s camera. I was satisfied with its operation and used it regularly. A few years later I was working at a job that was extremely stressful and not a healthy working environment. One morning getting ready for work I was stressing the day and passed out due to afib. My wife took me to the hospital and through every test all my numbers were beyond excellent and I was told that I was in excellent health and that the episode was brought on by stress. The relevance of this story is that while I was in the hospital on an actual heart monitor I was curious about my app. I took out my phone and checked it in reference to the hospital’s monitor and the irregularities were the same and it was about one or two beats off if that. My resting heart rate also matched. I was at that point thoroughly impressed. I have suggested it to friends and find it is a worthwhile tool to have.

Was Great

I first downloaded well let me say I purchased Azumio Heart Rate Checker when that was all you had to pay for; just the app. Of course they had a free version but I opted for the paid version because it had more features. Now this app has turned into one big in-app-purchase. Everything you click on; in an app you already paid for, opens up another screen wanting you to sign up for a premium subscription. There are thousands of similar free apps on the app store that offer the same services as this one but again I went with Azumio. Now I wish I would have never even downloaded this. Yes it will check my heart rate but then it jumps to screens you can’t even view unless you buy a subscription. I wanted this app because I have high blood pressure and have suffered numerous heart attacks and needed something to keep track of my heart rate. I don’t care about my weight nor do I care what Joe Blows heart rate is in another country. This use to be a straight forward heart rate monitor/tracker and greed has driven the developers away from what once made them great. If I was an athlete, weight lifter, or health nut then everything in the app would be fine. But not everyone is wanting everything thats offered in this app yet it’s constantly threw down their throat. I still monitor my heart rate and will do the Stand Up Test but then I close the app out just to forgo all the subscription pop ups. Sorry Azumio but this app just isn’t what it use to be.

This app is spot on the reading of my heart doctor!

I tested the accuracy of my heart rate while having an EKG at my PC and heart specialist. It was the exact same number. I personally have found that comforting knowing the rate is accurate. This week I needed a check up from my heart doctor but due to COVID-19 no one could go to the office without an emergency. He had seen this app work before and was confident that HEART RATE was properly monitoring my heart. I was able to report high numbers, low numbers and what I was doing! I told him I highly recommended this product! He agreed that I should. Some of his patients were even told about this app so they could find comfort but also to better know when to call his office! But!! Everyone should have this app. I am definitely going to upgrade mine for additional information.
