Glow is a free iPhone app that allows you to find out how people around you or in a specific geographic location are feeling. Imagine you are at a concert and you want to know the mood of the audience right this instant. You open up Glow on your iPhone and submit your feeling. Five stars for "awesome" and one star for, well"not so awesome". Each of these stars represents a color. One star is red and five stars is blue and everything in between is the combination of these two colors. Once you submit your feeling, Glow takes you to the Map View and shows you the general sentiment for a given location based on these colors and the mixing of them. The point is being able to share emotion with the cloud; to quantify happiness. Glow's purpose is to show you right now how people are feel
