Loren Brichter is a legend amongst iOS developers. The 28 year old developer is the creator of Tweetie, which eventually became the official Twitter app. He’s the guy behind fan favorite word game Letterpress. He’s the creator of ‘Pull To Refresh’, cell swipe and slide-out panels that have become synonymous features in mobile app development. Yet few people who aren’t app and design junkies even know who he is.
