Meta's AI Companion Muse Hits 10M U.S. Downloads in 40 Days
Meta's AI companion Muse has surpassed 10 million U.S. downloads within its first 40 days, making it the fastest-growing app since Threads. According to Sensor Tower, it reached about 10.9 million global downloads, with 10.2 million from the U.S., accounting for 94% of total downloads. Meta significantly boosted its visibility by allocating 39% of its ad budget to Muse in October, up from 23% in September, making it a top advertiser. Muse shows strong retention, with a 30% 7-day retention rate in the U.S., outperforming rivals like ChatGPT, Grok, and Claude, though it loses more users after the first day. Daily active users peaked at 2.5 million on October 16. Despite rapid growth, monetization faces hurdles due to banks and brokers blocking AI agents. The app has held the No. 1 U.S. App Store rank except for one day.
Meta's Muse achieving 10 million U.S. downloads in 40 days demonstrates Meta's powerful app distribution and advertising strategy, which could reshape the AI assistant landscape and intensify competition among AI chatbots.

Meta's AI Agent Muse Reaches No. 2 US App Store Rank
Meta's new consumer AI agent app, Muse, has climbed to No. 2 on the U.S. iOS App Store Top Charts since its launch on September 8, 2026. According to Sensor Tower data, Muse has been downloaded over 83,000 times on iOS in the U.S., though this lags behind the debut numbers of Meta's previous apps like Threads and Meta AI. The app's Android version ranks lower at No. 338 in the Productivity category on Google Play. The launch compares to competitor ChatGPT, which saw over 500,000 U.S. downloads in its first week. Meta faces competition from other agentic AI apps, notably Instinct, which recently raised $350 million and is valued at $2.5 billion. Muse's launch comes amid privacy concerns and follows Meta's $18 billion multistate settlement over social media harms.
Meta AI App Hits No. 5 After Muse Spark Launch
Meta launched Muse Spark, a new multimodal AI model, and updated its Meta AI app and website. Appfigures data show the Meta AI app jumped from No. 57 to No. 5 on the U.S. App Store immediately after the Muse Spark release, suggesting a large increase in installs. Appfigures reports 60.5 million total installs across App Store and Google Play (25 million in 2026) and a 138% download increase over the app’s first five months. Muse Spark accepts voice, text and image inputs, can spin up multiple subagents, and is designed to help with tasks such as health education, complex reasoning, and visual coding. Meta plans to roll the model out to WhatsApp, Instagram, Facebook, Messenger and its AI glasses in the coming weeks. Meta positions Muse Spark as an upgrade to Llama 4 and a step toward competing with OpenAI, Anthropic and Google.
Meta's Muse AI agent sees rapid adoption, shifts AI trade focus
Meta's AI companion app, Muse, launched on September 8, 2026, and achieved explosive adoption, surpassing 3.4 million downloads by late September and reaching 5 million in 22 days, outpacing ChatGPT's early growth. Available in the US and Canada across mobile, web, and WhatsApp, it offers a free tier with ~100M tokens weekly, plus Power ($20/mo) and Max ($100/mo) tiers. Promoted via house ads contributing only 6% of impressions, it topped app stores and shifted Wall Street's focus to consumer AI agents, with Morgan Stanley estimating $30 trillion in digitizable spending. However, friction emerged, including Amazon blocking the agent, a privacy incident, and high compute costs. Meta also launched the Meta Enterprise Platform, hired MongoDB's CEO, and partnered with Shopify and Expedia, while facing financial risks from a projected $180 billion cumulative spend on PSIA by 2027.
