From No. 57 to No. 5 on the US App Store in days. That's the chart jump the Meta AI app made after Meta launched Muse Spark, its new AI model.
The timing is precise. Just before the Muse Spark announcement, Meta AI was sitting well below the top 50 in free app rankings. After the launch, it climbed to No. 5 - and was still rising at time of reporting.
The standalone Meta AI app has historically struggled for downloads despite Meta's enormous user base. Facebook, Instagram, and WhatsApp have billions of combined users, but those users haven't been converting to Meta AI app installs at the rate ChatGPT and Gemini drive downloads. Meta AI has mostly lived as a feature embedded in apps people already use - not something they specifically seek out and install separately.
The Muse Spark launch changed that, at least briefly. App Store rankings are volatile - a No. 5 position can slip back within 48 hours once launch attention fades. But the speed of the move demonstrates something real: when Meta promotes a product across its own social platforms, it can drive installs at a scale most AI companies can't touch. The question is whether people who downloaded out of curiosity will stick around. Rankings spike on launch day; retention is where most AI apps actually struggle.
