Last night The Iconfactory released Twitterrific 5, a completely new iOS version of the grandaddy of Twitter apps. I reviewed the new app in detail when it came out, and the releases seems to have been met with a lot of positive feedback.
One of the developers behind Twitterrific, Craig Hockenberry, has lifted the curtain to give a behind the scenes look at the making of Twitterrific 5. A lot of work goes into making a great app.
