Pasadena-based mobile application and advertising developer Ubermedia said today that it has integrated social sharing tool Buffer with its latest version of its Twitter client software, Echofon. UberMedia said the integration allows users to share any Tweet inside the software to be socially shared by Buffer, with tracking of clicks, re-tweets, favorites, and mentions in a comprehensive dashboard. Financial details of the integration effort were not announced. UberMedia's Echofon client works on both the iPhone and Android. UberMedia is backed by Idealab. Buffer develops social sharing applications and tools. UberMedia has most recently been shifting its business model away from the Twitter client business, and more towards mobile advertising.
