Cardiograph is a fast and reliable way to measure your heart rate on iPhone and iPad. Using only your device’s built-in camera — with no additional hardware required — allows you to keep track of your heart’s rhythm anywhere and at any time. The detailed history records and ability to sync, tag, share and print individual measurements make it a versatile tool for monitoring your cardiovascular health.

Accurate Results, Almost Instantly
Having a quick and easy way to know how fast your heart is beating has many uses — from improving your exercise regime to keeping regular track of your heart’s condition, or even just for fun. Cardiograph makes that easy, with precise results that appear within a few seconds.

Clean, Simplistic Design
The minimalistic and intuitive design shows you everything at a glance and makes Cardiograph approachable and easy to use for everyone.

Detailed History
Save your measurements (including every individual heartbeat!) for future reference or for sharing with your family or health care professional. You can also add a label to each measurement depending on the intensity of your exercise or your activity level.

Export & Share Your Measurements
Each measurement can be shared, exported as a PDF file and even printed on paper directly from within the app. If you have our previous app, Cardiograph Classic, you can transfer all of your measurements to the new app with a couple of taps.

Designed for iPhone & iPad
Cardiograph is a native app that takes advantage of the iPhone & iPad’s distinctive features like the excellent cameras, 3D Touch (where available) and support for syncing with the Apple Health app (where available).

IMPORTANT: This application, although sufficiently accurate, is not meant as a replacement for professional medical equipment and qualified care. If you have any concerns about your heart’s condition, please consult your physician or general practitioner.

I love this app. I just walked 2.497 miles around our complex and came in the house after a breather and took my test.

No está actualizada

incardenas on

La aplicación no está actualizada, ni funciona bien con los dispositivos de doble y triple camara.

Fake waveform

Gary W Martin on

I also have the Kardia 6L EKG device. The waveform is totally fake. At least the CARDIIO app does not pretend to be EKG. That app shows actual blood flow variations more like a sine wave but real

Too short

From East Bay on

Too short to be able to see if the heart rhythm is irregular

Great pulse and cardiograph app

MarlinSheesley on

Very easy to use and record health data!

Not a real ekg

Regena111111111 on

This app is bound to give people anxiety. Folks this is not a real ekg and can not tell you anything about your rhythm. Get a Kardia or an Apple Watch if you want an ekg.

Measures well, save a poorly

HBH Mom on

I love the tracing and rate capture. It has been a great help managing heart rate. It is incredibly variable as to whether it saves a reading. Very frustrating!

Major flaw

PippinSays on

It show the heart rate ok, but it will only save it if the heart rate is regular and normal rate. I want to show my doctor when rate was irregular and jumped from fast to slow. It is worthless at this point.

Loud and inaccurate

BlooCube on

What’s with all the beeping when the volume is off? Took 4 resting readings in a row and they increased from 68 to 85. Used a real monitor and got a consistent 70. If you have heart issues and/or need to check your heart in public, this is not the app for you.

Interpretation 😧

Wish it did an interpretation
