App Description
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.
✓ Wear OS support
Cardiograph is specifically designed with Wear OS 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).

Frequently Asked Questions about Cardiograph - Heart Rate Meter APK
This is the universal variant — a single APK that contains native libraries for every CPU architecture. It installs on any Android device but is larger than per-architecture variants.
Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.
Android 23 (API level 36) or newer. Older devices will refuse the install.
Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.
All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
