CaMeasure -- use your camera to measure size or distance

I'm always amazed by all the novel uses of the camera on iOS devices — from taking your pulse to helping those who are colorblind determine colors — and wrote an article about that in a recent issue of the magazine. And I just received a press release for another. CaMeasure lets you use your camera to measure size or distance. It does this in one of two ways. For smaller objects such as furniture, the app asks you to put an object of known size, such as a sheet of paper or a credit card, by the object. The app then uses that to calculate size. Or for large objects, such as a building, a virtual object is superimposed on the building, and you scale this item in relationship to the object you want to measure. Interesting app, and always great to see yet another practical camera tool.
