Sensor Tower

Sensor Tower’s data increasingly frames the mobile market’s AI-era shift, from ChatGPT’s falling share to a surge in AI-assisted app launches on Apple’s App Store.

Who they are

Sensor Tower appears in coverage as a mobile-app intelligence and measurement source, supplying download, revenue, market-share and usage estimates that reporters use to assess app launches, platform economics and competitive shifts across the App Store, Android and major consumer apps.

The recent arc

Recent coverage has concentrated on AI apps and the accelerating supply of mobile software. In 2026, Sensor Tower data tracked ChatGPT’s share falling to 46.4% as Google’s Gemini reached 27.7% and Anthropic’s Claude 10.3%, while Bloomberg and TechCrunch used its download estimates to compare Muse’s early uptake with Meta AI and then chart Muse passing 10.9 million downloads after its September debut.

The focus has broadened from individual app launches toward market structure. Sensor Tower reported that India generated a record $345 million in mobile consumer spending in 2026’s second quarter, with ChatGPT leading downloads, and that roughly 560,000 apps reached Apple’s App Store in the first half of 2026, nearly matching the approximately 600,000 added during all of 2025 as vibecoded apps flooded the store. Its 2025 figures also placed global app spending at $85 billion and identified non-game apps overtaking games, which it attributed to GenAI demand.

The tension

The recurring tension is whether AI is redistributing power within mobile rather than merely enlarging it: ChatGPT faces rising Gemini and Claude shares, Muse’s launch is measured against Meta AI, and Apple’s App Store is absorbing a sharp influx of vibecoded apps. Sensor Tower’s reporting turns these contests into comparable indicators of downloads, spending and engagement, alongside its established tracking of TikTok, Instagram Reels and YouTube Shorts.

Why it matters

If the pattern holds, mobile-market analysis will increasingly hinge on whether AI demand produces durable consumer spending and usage, or simply a larger, noisier app catalog. Sensor Tower’s measures of store supply, revenue and adoption offer a common way to evaluate that question across Apple’s distribution ecosystem, fast-growing markets such as India, and the contest among leading AI products; early download momentum alone remains an incomplete test of staying power.
