Cardiograph is an application which measures your heart rate. You can save your results for future reference, keep track of multiple people with individual profiles, add notes and locations, and even print out your measurements for sharing or safe keeping.

Cardiograph uses your device's built-in camera to take pictures of your fingertip and calculate your heart's rhythm - the same approach used by professional medical equipment!

"I know you have the disclaimer on the screen but I don't care, Cardiograph saved my life. Your app was key to understanding what was going on and help the doctors understand too."
Bob Spadafora - *****

"Comparing heart rates with family over the holidays is fun."
Txyak – ****

"Wanna impress a friend with a cool app. This is the one to get."
Mattyray – *****

"After having two heart valve replacements and a by-pass, I feel it is not only smart - but also necessary - to have such a reliable heart rate monitor with me everywhere I go."
Dantv – *****

"I am an EMT and it helps me actually see what is going on. It is by no means definitive like a monitor but it is a great indicator of problems I would not see otherwise."
Granniem – ****

"I had a pulse oximeter on one hand, medical quality, and my iPhone app in the other and the app was dead-on accurate."
Like it but hate it – *****

• Measure your heart rate

It's never been easier to know what your heart rate is! Without any external hardware, just using the built-in camera of your smartphone or tablet, you can get accurate readings almost instantly.

Knowing how fast your heart is beating can be very useful when exercising, if you're under stress, if you have a heart-related medical condition, or even just out of curiosity.

• Track your results

Every measurement you take is saved to your personal history, so you can keep track over time. In addition to the date and time of the measurement, you can also save the location at which it was taken (and see them on a map), and even add a quick note to effortlessly organize your history.

• Multiple profiles

Cardiograph is perfectly tailored to allow multiple people to use the app on a shared device. You can create profiles for each of your family members or friends, and each of them has their own individual measurement history.

• Export & Print

Each measurement can be exported in full detail to a portable format that you can later send via e-mail, upload on the web or even print right from the app itself (with an AirPrint™ compatible printer).

• Clean and intuitive design

Inspired by real-life medical equipment, Cardiograph is a pleasure to use. The streamlined and clutter-free design makes it seem instantly familiar, so you can focus on using the app instead of navigating through series of confusing screens.

• Built-in user guide

If you're having trouble with the app, or you want to make the most out of it, you can access the comprehensive help manual right from within the app itself.

• Universal application with iCloud® sync

Cardiograph is an universal application - it runs on the iPhone, the iPad, and the iPod touch.
Install Cardiograph on multiple devices with iOS 5.0+, and all your profiles and measurements will be in sync! Manage your profiles and measurements on one device, and the changes are instantly reflected on all the others.

Please note: If your device doesn't have a built-in camera flash, you need to take your measurements in a well lit environment (bright sunlight or close to a light source).

Reads 20-30 higher heart rate than actual. Used BP Cuff to get actual heart rate. Not worth the 99cent I paid.

Very good


Cubhole on

This App worked very easy on pre-iPhone 13. I was stumped at first and then found the App works very well with one of the new photo lenses. You will have to move your finger around until you find the correct lens.

It’s what I need!

The best design! It stands out!

scott.forstall on

Really hate the flat design. This skeuomorphic design is outstanding, keep it alive!

Not a happy camper

need a pulse checker on

This doesn’t work. I paid for it and it never has worked consistently. When you pay for something, I expect it to work !

Will not show arrhythmias!

Frcalky on

App will only record a regular rhythm. This is not beneficial if trying to document issues to show your physician. Only gives you a 0 for rate and no rhythm strip. Needs button to allow you to accept strip if not perfect regular heart rate.

Fake graph

Gary W Martin on

Pulse number is probably correct but the waveform is a phony animation lol that has nothing to do with the camera’s flash whereas cardiio waveform actually relates to changes in blood flow.


jpierclay on

Does work anymore

@$&2344990 on

I lord this and it worked for literally four days. Them suddenly no matter what I do it doesn’t seem to work. Bummer
