Heart Rate Check is a free Android app developed by Plus One Health that measures your heart rate by using your mobile's camera. This app offers unlimited records and measurements, and all the heartbeat data are saved and displayed to you. It is suitable for people who care about their health condition or need to monitor their heart rate regularly. It can also be used by people who want to measure their workout intensity, such as running, gym, or any kind of training.

The Heart Rate Check app detects your pulse by using the camera of your phone. When your heart beats, the volume of the blood flowing through your finger tip changes. This app uses the camera to capture the image and uses algorithms to recognize the heartbeat. It suggests fitness level information, and shows your exercise intensity level calculated based on your personalized maximum heart rate zone. However, please be noted that irregular heartbeat information cannot be identified because it may be a fault trigger due to the poor steadiness of the finger putting on the camera.
