Pulse Phone is an application that measures your heart rate by using the IPhone's built-in camera and flash. The application detects small variations in the opacity of your finger as blood flows through it. --- See a video of the app here: --- http://tiny.cc/pulsephone --- To use, go to the "Live" tab and lightly place the tip of your index finger over the entire camera. After a few seconds your pulse will be detected and an animation of the data displayed. You may save recordings and email them to yourself in the "History" tab. --- The app was originally programmed in March 2009 for the first iPhone. The current release is designed to run on iPhone 4 as it uses the built-in flash to illuminate the finger. The app will also run on iPhones and iPods that don't have a flash, so long as they have OS4.1 or higher, but then you will need to hold up the phone very steady to a bright light to get acceptable results. --- For tech support or inquiries please contact pulsephone@antimodular.com
