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?

As you point your camera at the scene around you, specific information related to your location appears on the screen — superimposed over the live image. Pretty amazing. There's a video demo on YouTube that gives you an idea how it works.
