I compared it to a monitor I have for my fingers to measure my heartbeat and I done old fashion pulse check and count method. Both times I tested and compared, it was dead on." HOW IT WORKS ▸Place and lightly hold your forefinger on the back camera lens and stay still. The heart rate is shown after few seconds. ▸Do not press too hard when you measure your pulse heart rate, otherwise blood circulation will be altered and the results in your pulse app could be affected. ▸Make sure there is a bright background, otherwise the app won't be able to detect your heartbeat. ▸The camera flash can help to create a bright background. It will get hot, don't burn yourself. NOTES ▸Heart rate monitor is not a medical device. Measurements and statistics are intended for informational and educational purposes only, to support general health and wellness. ▸For some devices, heart rate monitor may make the LED flash very hot.
