pull-to-refresh

The Wall Street Journal published a piece last night that profiled influential app developer Loren Brichter of Atebits and Tweetie fame. The 28-year-old developer is the man behind several apps that were first to implement or help popularize well-known gestures and UI features that have since become design standards for many popular apps and developers. Perhaps the best example is “pull-to-refresh”—a feature that Brichter built into his Tweetie app before selling to Twitter:

Mr. Brichter got his start in the mobile industry while at Apple from 2006 to 2007 as part of a five-person group working out early kinks in technology that made the iPhone’s graphics hardware and software communicate… In 2008, Mr. Brichter built Tweetie to have a better way to use Twitter and eventually included the “pull-to-refresh” feature. After selling the app to Twitter for what he says was “single digit millions” in 2010, he stayed on at Twitter working remotely on the company’s apps for about a year and a half. He left to keep experimenting.

Other features Brichter helped to popularize include the slide-out panels that we see in apps such as Facebook and a feature described as “cell swipe” that’s popular in Twitter apps for revealing lists of hidden functions by swiping. WSJ was quick to point out that Brichter has filed for a patent on at least the “pull-to-refresh” gesture (now owned by Twitter), but Brichter explained that he allows most developers to implement the features freely:
