Heart Rate - Free

Amazing Camera Apps

Add barcode readers, augmented reality, fax, language translation, heart rate monitor, and more to your iPhone or 4th gen iPod touch

The range of creative and practical apps that use the camera in unusual ways is astonishing. Who would have thought that you could use it as a heart rate monitor or a business card reader? There's even an app for those who are colorblind, to show them the colors present in any object you photograph.

Apple made a brilliant decision when it let developers create apps that access the camera input and use it in non-traditional ways. In this month's column, I offer a roundup of some of these apps.

Heart Rate - Free -- app uses camera to measure your heart rate

image

Heart Rate - Free is a newly released app that actually measures your heart rate using the iPhone 4 camera. (The app only works with iPhone 4.) You simply put your finger over the camera lens, and the app measures the minute changes in skin color caused by the ebb and flow of blood in your finger. They say that the app isn't intended for medical use (standard disclaimer) but that it provides an accurate measure of your pulse. This is one more app for my forthcoming article on the innovative uses of the camera.
