Other Comments: 

This is a very interesting little utility. The app itself is very accessible.

To completely grasp in what is going on will take some time to adjust to fully understand how it works. I highly recommend in reading the Manual and the Tutorial that comes with this app.

One thing to note about the color identification is that I believe it can recognize up to 192 different colors. The one thing that it doesn't have is the ability to turn on your Torch. I find that Color Identifications with devices that has the Torch does a better job of recognizing it. So for this app you really need to have a good lighting for a more accurate reading.

The other options to sense things like the walls and objects is quite fascinating. I almost feel like a bat or it would seem like that this is what bat's must hear when they use their sonar kind of like mechnisim to detect things. As this may not be used reliablely in an everyday situation it is fun to play with.

The other feature that it also provide is the light detection. As you would keep in mind that when focused on to a bright source the louder that the device will sound and the ability to go away or left/right of the source that it will be heard by the direction on your headphones. Very much like the Light Detector but this app isn't as annoying as you would find in the Light Detector.

So you really get three functionality in this one single app that is FREE. However, there is an in-app purchase if you want the refreshing rate to be faster and more accurate. Plus, of course you would be helping the developer in making this app possible for us and supporting him for the effort.
