📝 About this app
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.
If you’re having issues with Cardiograph, check out the “More” section within the app or contact us at our support e-mail and we’ll help you out.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
