Muse Spark Launches; Meta AI Jumps From No. 57 to No. 5 on the App Store
Meta launched Muse Spark on April 9, 2026. The Meta AI app was ranked No. 57 on the U.S. App Store. By April 8 it was No. 5, behind ChatGPT at No. 1, Claude at No. 2, and Gemini at No. 3.
The Numbers
U.S. iOS downloads hit approximately 46,000 on April 8, an 87% day-over-day increase. Android U.S. downloads rose 3% the same day. Daily U.S. web visitors rose more than 450% day-over-day and landed more than 570% above the prior 30-day average.
The app has 60.5 million total installs across App Store and Google Play. 25 million of those came in 2026. Downloads over the first five months of this cycle are up 138% compared to the equivalent earlier period. India is the top market by downloads, followed by the U.S., Brazil, Pakistan, and Mexico.
What Muse Spark Does
Muse Spark accepts voice, text, and image input. It supports visual coding, meaning users can describe a website or mini-game and receive a working result. It can spawn multiple subagents to handle a single query in parallel.
Rollout to WhatsApp, Instagram, Facebook, Messenger, and Meta AI glasses is scheduled for coming weeks. Meta's distribution advantage over standalone AI apps is obvious on paper. Whether engagement follows installs is a different question.
The Wang Factor
Muse Spark is the first model release under Alexandr Wang. Meta recruited Wang from Scale AI to overhaul its AI efforts and put him in charge of Meta's Superintelligence Labs. Meta has also invested $14.3 billion in Scale AI. Recruiting the founder of a company you've already bet heavily on to run your AI division is a clear consolidation of strategy.
The launch spike is real. One day of App Store movement does not establish whether Muse Spark holds attention beyond the announcement. That data takes weeks to emerge.
