The chronological feed option can be accessed by tapping on a sparkle-shaped icon at the top right of the Twitter app, which changes the view between latest tweets and the current top tweets option.
Twitter originally used a reverse chronological feed, showing the newest tweets at the top of the app before switching to a timeline that places a selection of top tweets first.
It's been years since Twitter switched to the top tweets timeline style, and many Twitter users have missed being able to view content chronologically.
New on iOS! Starting today, you can tap ✨ to switch between the latest and top Tweets in your timeline. Coming soon to Android. pic.twitter.com/6B9OQG391S— Twitter (@Twitter) December 18, 2018
Twitter in September introduced an option to turn off the "Show the best Tweets first" feature, but today's new toggle goes further and makes it easier to get a chronological timeline view.
Twitter says the chronological feed toggle is available on iOS today and will roll out to the web and Android devices soon.
