Heart Rate Cardio Monitor is a free lifestyle app developed by Mauze Soft for Android. As the name suggests, it measures your heart rate using your phone camera. All you need to do is place your fingertip on the back camera lens to start measuring. The app uses your phone camera flash to improve lighting quality for accurate measurements. It supports a wide range of devices and can use either the main or front camera. Additionally, the app includes a built-in measurement log for convenience.

The app uses a unique principle of measurement based on the change in skin permeability to daylight due to blood pulsations in the capillaries. These minor changes are recorded on the mobile device's camera and measured with special detection and filtering algorithms in real-time. If the app fails to measure your heart rate the first time, simply try using another finger or switch to the front camera.

In summary, Heart Rate Cardio Monitor is a simple and fast way to measure your heart rate using your phone camera.
