About this app

Cardiograph is an application which measures your heart rate. You can save your results for future reference and keep track of multiple people with individual profiles.

Cardiograph uses your device's built-in camera or dedicated sensor to calculate your heart's rhythm - the same approach used by professional medical equipment!

✓ 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/sensor of your smartphone or tablet, you can get accurate readings almost instantly.

✓ Know how fast your heart is beating

It can be very useful while 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.

✓ 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.

✓ Clean and intuitive design

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 screens.

✓ Android Wear OS support

Cardiograph is specifically designed with Android Wear support. You can measure your pulse using the hear rate sensor in your smartwatch. Please note that Cardiograph will work on smartwatches with a heart rate sensor only.


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).

I have an irregular heartbeat. Most apps stop their testing when they pick up my irregular pattern. I needed an app that would not only tell me what my heart rate was, but actually show me the historical cardiographs so I could show my doctor. This app does it all. It lets me monitor as long as I want and saves an actual picture of what it monitors. Thank you!

Best! Ive used many... I suffer from mental and physical health issues. When my anxiety shoots up, I have to do breathing exercises, and I have to monitor my heart rate. So I know what, and when things are happ. This app really is incredible that works immidiate, and you can print/Share out your own cardiograph!!! That is huge for me I mean huge! You can go back to different dates, whatever you want to do if you're looking for something to monitor your heart rate I absolutely recommend this!

Very frequently double counts pulses: when counting pulses by hand shows ~60 BPM the app will show ~100, with double pulses right next to eachother, then the next will be normally spaced. Then, because it only attempts to read a pulse for a few seconds if it reads anything, it will report a pulse around 90 in the scenario above. Another pulee app on my phone does not have these flaws, so this is an issue with the app, not the hardware.
