Threads' user base has plummeted more than 80%. Meta's app ended July with just 8 million daily active users.

• Threads closed July with 8 million daily active users, down 82% from its peak, according to Sensor Tower data.
• Meta's Twitter clone, which launched July 5, had 44 million daily active users on July 7.
• Mark Zuckerberg has acknowledged the decline, but has said he's "quite optimistic" about the app.

Meta released Threads in early July to fanfare across the social media landscape — but most of those fans haven't stuck around.

Data from the market intelligence firm Sensor Tower showed Meta's Twitter clone ended July with 8 million daily active users. That's about an 82% drop from its peak daily active user count of 44 million just days after Threads launched, Sensor Tower reported. 

The data presents a clear picture of where user engagement with the app stands nearly a month after it debuted and gained 100 million users in its first five days.

But this isn't the first sign of declining activity on Threads. 

Last Thursday, CEO Mark Zuckerberg talked with Meta employees about Threads' sagging user engagement, reportedly admitting the app lost over half its users since its launch.

Sensor Tower pointed to the fact that Threads still lacks popular features, like direct messaging and content produced by buzzy influencers, as a potential reason behind the dwindling user base.

When asked for comment by Insider, a Meta spokesperson pointed to Zuckerberg's remarks during Meta's earnings call last Wednesday, during which he shared that he was "quite optimistic" about Threads' trajectory.

"We saw unprecedented growth out of the gate, and more importantly we're seeing more people coming back daily than I'd expected," Zuckerberg said. He added that Meta will prioritize "retention and improving the basics" of the app before shifting to growth and monetization.

Instagram CEO Adam Mosseri has made similar comments on gradually adding new features to Threads. On July 11, Mosseri assured users that his team would add what he called "obvious missing features" to the app, such as tools to edit posts and a feed that allows users to see content just from accounts they follow.

"We're clearly way out over our skis on this, but the team is pumped to start shipping improvements this week," Mosseri wrote, referencing the speedy production and launch of Threads.

Since then, Threads has added a following tab on its feed, among other features, Threads programmer Cameron Roth wrote in a Threads post.

It's still to be determined if that will be enough to keep Threads from unraveling.
