Another market intelligence firm, Sensor Tower, estimated that Meta AI saw around 46,000 U.S. iOS app downloads on April 8, 2026, an increase of 87% day-over-day. On Android, U.S. downloads of Meta AI rose just 3% day-over-day on April 8.

Meta says its new AI model, which is available on both the web and mobile, is a significant upgrade over its earlier Llama 4 models. It’s also the company’s latest attempt to catch up to rivals like OpenAI and Anthropic, an effort that’s already cost Meta billions in recruiting AI talent, in addition to its $14.3 billion investment in Scale AI.

Currently, Muse Spark accepts multimodal input, including voice, text, and images, and has been designed to perform well on a number of tasks, like helping people learn about their health and reasoning through complex questions in areas like science and math. It can also aid in visual coding, letting users create websites and mini-games from prompts.

Plus, Meta AI is able to launch multiple subagents to handle users’ questions, the company said.
