Beware - this app simply doesn’t work with the flagship Apple iPhone 11 Pro Max. The problem seems to be the three cameras built into the iPhone 11 Pro Max. I contacted the help desk who in turn simply replied that I should read the directions. Either the help desk people don’t realize their own app directions are no longer up to date for current versions of iPhone, or I hope I’m wrong but perhaps they simply don’t care about customers of this app any longer. The app directions only refer to iPhones with a single camera. If it was just experimenting with placing my finger over one of the three cameras of the iPhone 11 Pro Max, or some combination of cameras, I wouldn’t have had to see if the help desk could actually “help” a customer. If you’re using most any version of iPhone less than the iPhone 11 Pro Max, this app is fantastic and works well. I hope the developer decides to update this app for Apple’s flagship iPhone. I also hope the help desk procedures get updated to provide actual help to customers.

I paid for the waveform measurement thinking it would give a little more detail about what is seen in the heart rate, like maybe a missing p wave, or too long a length between certain parts of the waveform...you know, length of time to the T wave or whatever. I didn’t expect the only information shown after 7.99 (a lot by app standards) to only say: -.2 sec. <—-that’s it. That’s what you get for 7.99. Okay? How is that even remotely worth any money at all and how does that help me? I downloaded the app and would pay 50 bucks if it helped me figure out why I get breathless for no reason after never smoking and while just sitting. People downloading heart rate apps have heart rate questions. I don’t expect it to be a doctor in an app. But I do expect 7.99 to measure something resembling anything. I feel betrayed. I feel stupid for parting with that much money. I made an assumption that 7.99 meant the waveform was analyzed. It’s not.

If you want to measure your resting heart rate, this is a decent option, I found it works most of the time. However, it is totally unreliable in measuring heart rate after activity. I tried over 20 times to measure my heart rate after a run, and i was standing so still that my heart rate was shaking my body. The app starts to measure it and creates the beginning of a waveform but before a number is displayed it quits the process and you have to start over. My heart rate was 192 by the time the app actually measured it because I had to sprint for so long until I could get a reading. So just get a heart rate moniter from target or something if you want to get readings while exercising or after exercising.
