Twitter has changed the way the Explore tab works in its official iOS app, with entries now organized based on topic and divided up into separate navigable sections. Twitter says the update should make exploring the platform easier than ever, with users able to find trending tweets on specific topics by tapping the designated tabs for news, sports, fun, and entertainment. The searchable Explore section, introduced early last year, gives users one-stop access to trends, search, Moments, and live video, with ads also showing up there in the last few months. Users in the United States can start accessing the new Explore tabs today, with availability likely to roll out gradually to other regions and territories, all being well. Earlier this month, Twitter added a new compose button to its official mobile app for iOS, with the aim of enabling one-handed scrolling and tweet composing. Twitter is also testing an option to quickly access a classic reverse chronological timeline, as promised back in September.
