A free app for Android, by Zombie Soup.
Heart Rate is an app that lets you measure your heart rate using a finger tip pulse oximeter (FTO). This is a handy app for anyone who needs to check their heart rate regularly or for those who want to keep track of their physical condition.
The app is based on the same technology used by pulse oximeters, which are a kind of non-invasive blood pressure monitor.
How does a pulse oximeter work?
A pulse oximeter is a device that measures the oxygen saturation of the blood. This is done by using a light sensor and a color sensor to measure the blood oxygen level. The device is used to measure the oxygen saturation of the blood in the body, including the brain, the heart, and the lungs.
