Color App for Android and iPhone can be downloaded by calling a certain number (call **COLOR (**26567)). How exactly it works? I'm interested in both the way it redirects the user on the UI level as well as the technology used.
I understand that "**" is some kind of special prefix used it US - can it be done without this prefix (i.e. by calling an typical cellphone/stationary number)?.
I am posting this question here because I believe it is related to programming. I also cannot check it as I live outside US.
The answer below is from the Developers website: http://support.color.com/home
I guess the computer-based answering machine records your number when you call it, and then sends out a text message with a direct link to the app. Quite simple and elegant solution.
The easiest way is to call *COLOR (*26567) from your device. You will instantly receive a text message with a link to download the app from the Apple App store or Android Market.
