*** Featured on The Doctors (CBS), ABC News and more ***
MEASURE YOUR HEART RATE:

Blood absorbs light. Every time your heart beats, the blood flow to your finger increases, causing more light to be absorbed. In between beats, less light is absorbed. By using your smartphone camera to capture tiny changes in reflected light from your finger, Cardiio can calculate your heart rate.
**IMPORTANT TIPS FOR BEST RESULTS
• ALWAYS hold your phone steady, keep still, and don’t talk during a measurement.
• Make sure your fingers are not cold.
• Cover the entire back camera lightly with your finger; Don't press too hard to avoid restricting blood flow to your finger.

Ratings and Reviews
I tried several deferent apps , some ridiculously expensive, asking for yearly subscription (Don’t know what for). None of were as accurate as this Cardiio app. and I am using the FREE VERSION. For ONLY A ONE TIME FEE OF $9.99 you can add 6 or 7 more useful features, but if you decide to have the free version, that would be good enough, There would be No pop ups of advertisement or anything like that. I really like the fact that makers of this app are very honest people. Thank you.
I READ AMOUNG SOME REVIEWS THAT THE PULSE READER ONLY WORKS LIKE 5 PERCENT OF THE TIMES. TO ME, THAT IS A GOOD THING, BECAUSE IT WANTS TO MAKE SURE THAT THE READING OF PULSE IS ACCURATE . SPECIFICALLY IF YOUR FINGERS ARE COLD OR DIRTY OR THE CAMERA LENS IS DIRTY. BUT ON MY CASE IT WAS THE COLD FINGERS. JUST PLACE THE FINGER UNDER YOUR ARM FOR FEW SECOND TO GET WARM AND TRY AGAIN . FOR ME, IT WORKED EVERY TIME.
Doesn’t work with iPhone 11 Pro Max
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.
Paid 7.99 for the waveform measurement
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.
