According to top tech blogger Jane Manchun Wong, the micro-blogging site have started trialling the new update on some accounts.
Wong has explained that it works by shutting down notifications for three set times of one hour, three hours and 12 hours, ideal for those who want to take a small break from social media.
The app has only just launched it's "shiny" new desktop site.
As well as a new "updated look and feel" and the introduction of Dark Mode, the micro-blogging site also has a Bookmarks feature and they've moved Trends to the right hand side of the page.
You can also change the display colours around and an Explore feature has been added which has videos and local content defined by the user's location.
They said: "We are starting to roll out a new Twitter.com - a refreshed and updated website that is faster, easier to navigate and more personalised.
"The site has an updated look and feel that is more consistent with the Twitter you see on other devices."
One feature which still hasn't been implement by Twitter, but which many people have called for is an edit button.
The update came after new features including a new swipe gesture to allow people to like - or reply to - tweets, and thread labels to clearly identify the original poster and a way to view profiles while keeping you in your timeline were teased.
Twitter's Sara Haider said: "Our goal is to make conversations easier to understand, and with the new threaded layout, people told us they found conversations easier to follow and liked seeing more of the conversation.
"Hiding engagements in replies resulted in the most mixed reviews: While some found themselves focusing more on the conversation as opposed to the metrics, others felt that the extra step to tap made it harder to Like and Retweet replies.
"Some felt that replies can get crowded, especially in long conversations. Lengthy threads become harder to read due to indentation and too many "Show more" buttons.
"Most people prefer the twttr reply highlighting, but also expressed visibility issues in dark mode. There was overall support for replying on twttr, specifically with the ability to reply in one place within a conversation; yet at times, it was confusing who you're replying to."
