Twitterrific is a macOS and iOS client for the social networking site Twitter created by The Iconfactory and was the first Twitter desktop client to come to macOS. It lets users view "tweets" or micro-blog posts on the Twitter website in real time as well as publish their own. Twitterrific is closed source software.
The program's main window uses a translucent black theme similar to certain palettes used in Aperture, iPhoto and other Apple Inc. software. Users may choose to view the full public timeline or just the friends feed. Users can also click on links to view the poster's profile or mark a tweet as a favorite.
Twitterrific also provides functionality to upload images and videos for posting on Twitter.
Version 3 changed Twitterrific into advertising supported shareware; every hour an ad is refreshed to the top of the list. Users who buy the program receive no ads. Other changes in version 3 mostly added compatibility with Mac OS X 10.5 and incorporated newer Twitter features like direct messaging.
On April 1, 2010, The Iconfactory released Twitterrific for iPad (Version 1.0), ready for the iPad's US launch on April 3. On June 24, a version of Twitterrific was launched (version 3.0) that was universally compatible with the iPhone, iPod touch and the iPad.
On October 10, 2017, the Mac application received a 5.0 update and was added to the Mac App Store.
On June 13, 2019, the iOS version 6.0 was announced. It disregarded previous in-app purchases. Users who had previously paid not to see ads were shown ads again. Iconfactory regards Twitterific 6.0 as a new app but does not give their existing users the option of staying on Twitterific 5.x.
