It is not for everybody, that's for sure. But if you want to run a giveaway of iOS promo codes on Twitter then you'll see that it is kind of a tedious task. You need to constantly check who retweeted your tweet, get a new promo code from the list, send a message to the person, delete the promo code from the list of available.. I was so bored doing that, I decided to build this service. :) Also, you get extra exposure every time when your tweet is retweeted by one of your followers.
