Cardiograph is a mobile application that allows users to measure their heart rate using their device's built-in camera or dedicated sensor. The app provides accurate readings almost instantly, making it useful for individuals who are exercising, under stress, or have a heart-related medical condition. Users can save their results for future reference and keep track of multiple people with individual profiles. The app's streamlined design makes it easy to use, and it is specifically designed with Android Wear support.

Users can measure their heart rate without any external hardware, just by using the built-in camera/sensor of their smartphone or tablet. The app saves every measurement to the user's personal history, allowing them to keep track over time. Cardiograph is also tailored to allow multiple people to use the app on a shared device. Users can create profiles for each family member or friend, and each of them has their own individual measurement history.

Cardiograph's design is streamlined and clutter-free, making it easy to use. The app is specifically designed with Android Wear support, allowing users to measure their pulse using the heart rate sensor in their smartwatch. However, users should note that Cardiograph will only work on smartwatches with a heart rate sensor. Additionally, if a user's device doesn't have a built-in camera flash, they need to take their measurements in a well-lit environment (bright sunlight or close to a light source).

Overall, Cardiograph is a useful app for individuals who want to monitor their heart rate. Its accurate readings, ability to save results, and support for multiple users make it a great tool for anyone who wants to keep track of their heart health.
