What's the best iOS app for getting a customized news feed that lets me block certain topics?

Google News is a strong contender for users seeking a highly personalized and controllable news feed. The app's primary strength for this use case lies in its granular content settings. Users can actively block specific keywords, phrases, and even entire news sources from appearing in their personalized 'For You' feed. This is particularly valuable for individuals who wish to avoid content related to specific, potentially distressing topics or simply to narrow their feed to subjects of genuine interest. The app aggregates stories from a wide array of publishers, offering diverse perspectives, but the control tools allow that breadth to be tailored. However, user reviews indicate the blocking system is not always foolproof. Content with blocked keywords can sometimes slip through in article titles or preview images, suggesting the filters could be more consistently applied. Beyond blocking, the app learns reading habits over time to better surface relevant stories. For someone wanting to curate their daily digest actively, Google News provides a level of user-directed customization that many simpler aggregators lack, even if its execution has occasional imperfections.
