Quickly, it can be said that Twitter has updated their official Twitter app for iOS and Android. The changes? Improvements to discover, search and notifications, allowing users to view “Activity” — described by the social network as a “stream of updates that shows which tweets are favorited or retweeted by the people you follow and which accounts those people follow or add to lists.” Very nice definition, indeed. It’s available as an update on both the App Store and Google Play Store for download right now. Your call, humans.
