Meta's latest AI app, Muse, may be the social giant's next big thing, according to new estimates from market intelligence provider Apptopia. In its first twelve days on the market, Muse was downloaded more times on mobile than ChatGPT was in its first twelve days. The comparison covers the U.S. and Canada markets only, because comparing things globally would be far too sensible.

Muse also has more daily active users than ChatGPT had at the same point, Apptopia found. Until now, an exact apples-to-apples comparison was difficult, since the two apps pursued different launch strategies: ChatGPT arrived on mobile globally but only on iOS, while Muse is available on both Apple's App Store and Google Play, but only in the U.S. and Canada. To align the numbers, Apptopia looked only at iOS data for the U.S. and Canada for both apps during their first twelve days. In that subset, Muse saw 1.8 million downloads to ChatGPT's 1.3 million.

Overall, Muse has seen 2.8 million total installs globally in its first 12 days, the firm said. Its growth hasn't stagnated, either. Muse moved from its original position as No. 2 overall on the U.S. App Store immediately after launch to now No. 1, as Business Insider reported on Friday. That jump put it higher than ChatGPT, the outlet noted. Another firm, Appfigures, said at the time that Muse had then crossed 1 million downloads.

Apptopia's data also indicates Muse's U.S. daily active users are now higher than ChatGPT's were at the same point after its launch. Comparing just U.S. mobile app daily active users, Muse comes in higher with 642,000 daily users compared with 231,000 for ChatGPT at the time.

To be fair to the fact that Muse is available across both iOS and Android while ChatGPT launched on iOS only, Apptopia narrowed the comparison to iOS alone. Even there, Muse comes in higher with 359,000 daily active users on iOS, still above ChatGPT's figures from that period.

Apptopia can only provide third-party estimates about an app's downloads and active users; it doesn't have direct access to Meta's internal figures. But even if these numbers are only correct from a general "ballpark" perspective, they indicate Muse could have a shot at becoming Meta's newest top app.

Meta already perfected its cross-promotion strategy when it launched Instagram's Threads, which now has 500+ million users, thanks to heavy marketing and integrations in Meta's largest apps, including Instagram and Facebook. Muse is likely to get a similar push, given that the AI app can connect with both of those platforms. It also works inside WhatsApp, so that could give it another boost.

While Apptopia doesn't have visibility into Meta's cross-promotion efforts or ads directly, it did note that over 95% of Muse's users are also Facebook users and 63% are Instagram users.

Meta, which has been asked for comment, has not yet shared public figures related to Muse's early adoption.
