Heart Rate App

This is very helpful for people who have any issues with their heart rate, skips, palpitations, heart issues, bc at the very moment you feel a difference or discomfort you can take your heart rate, see the live read out of the skips or palpitations, & generate a report that you just print off & take to your DR. There’s also a “stress test”, tho that name isn’t exactly a medical grade stress test in which either a pt is put on a treadmill & made to go to their carefully calculated highest HR for age & wt, while they’re heart is monitored before during & after., or a pt is given a med IV that raises the BP & HR to this calculation. This stress test monitors only HR while you’re sitting then beeps for you to stand for about 15 secs. It then shows the HR on a graph, & another bar shows where you fall as far as at rest, less fit, all the way to fit. This confuses me bc you’re sitting/standing, not being active to tell if you’re fit. Then it gives a % from 0 to 30% which it doesn’t explain your score or even what the % means, & I’m an RN who’s worked in cardiology testing!
I wish it included an 02 sensor, so if there’s an issue, that would be a solid piece of information, since lung probs can cause or be effected by the heart. Overall I find it very helpful for my Afib. And it’s free!;)

Does exactly what it says, and for an unbeatable price!

I use this app all the time and have been using it for going on 4 years. I like to monitor my pulse in different mental states and under the influence of different substances. I know, I’m odd. Without upgrading it takes fairly accurate readings, you can create custom tags to apply to your readings, add notes to your individual readings for more specificity, and it saves the actual chart from every reading. My only complaints are minor to the point of almost being negligible. For the chart there seems to be some accelerometer involvement instead of being purely based on the cameras readings, and the result it gives you after the 15 second reading is your final pulse at the end of the test and not an average of the 15 seconds. Anyone who is curious about how different variables alter your physiological state and want an easy way to test, notate, categorize, chart, and compare, then this is the app for you. Did I mention that it does all of this for free? Yea, that’s a pretty big deal for all of this functionality.

Great App!

I am a 38 yo female with Sarcoidosis. I also have a vascular defect in my heart. One of my coronary arteries is basically nonfunctional because it didn’t grow with my heart as I got bigger. I have runs of SVT and LOTS of palpitations/PVCs. So I have to take a beta blocker twice a day to keep myself from going into SVT and subsequent VT or VFib. Rapid ventricular or even supraventricular arrhythmias tend to eventually deteriorate into lethal ones because our hearts aren’t supposed to beat at those rates for very long. While this app doesn’t give you an EKG reading, it does accurately measure your pulse rate and you can see when there are irregularities. For instance, when I have palpitations, it is seen as a dip or a pause on the screen. It just confirms the irregularities. I am a registered nurse so that’s how I know what is going on with my heart, but this is definitely useful for anyone who needs to monitor their pulse for whatever reason. The best part is that it’s completely FREE! You can pay for other features if you want them, but I am very appreciative of this free service that helps me to monitor my condition. Thank you!
