A surge in mobile app users is no longer the only factor driving global growth. Why? This tale concerns spending, artificial intelligence, and attention. According to Sensor Tower, consumer spending inside apps has surpassed that of mobile games in 2025, despite low downloads over the past few years.

 

The meaning of "market size" differs depending on the individuals assessing it, including founders, developers, investors, and marketers. The instructions in this booklet keep three lenses separate:

 

Consumer spending is the amount paid by individuals for in-app purchases, subscriptions and paid apps on app stores (Sensor Tower).

 

The revenue figures of research firms, which are largely proprietary, are used to estimate the size of the analyst market.

 

The Ecosystem billings for all App Store app purchases, including physical goods, were commissioned by Apple.

 

The article does not merge the two, and it excludes mobile app development services, standalone mobile gaming and smartphone hardware, which are distinct markets.

 

Worldwide mobile app market size and growth? 

By 2025, what would be the market size? 

Consumer spending on iOS and Google Play apps is set to rise 10.6% year over year, with Sensor Tower reporting $167 billion in global spending from last decade. The revenue estimates for the mobile application industry published by research firms suggest that it will be around $242 billion to $298 billion in 2025. 

 

 

The public summaries do not provide a complete breakdown of what revenue is included in these vendor estimates. According to a secondary article, MarketIntelo's projection for 2025 is significantly lower at $156.0 billion (128% CAGR to 2034).

Historical Growth of the Mobile App Market

The mobile app industry growth story has three phases.

Pandemic surge (2020–2021). Sensor Tower reported first-time downloads up 24% to 143 billion in 2020 across the App Store and Google Play. In early 2021 it forecast consumer spending would reach $270 billion by 2025.

The pause (2022). Downloads slipped 0.9% to 142 billion, and mobile game spending fell to $79 billion from $86 billion in 2021. Data.ai, now part of Sensor Tower, described a roughly 2% dip in consumer spending.

Monetization era (2023–2025). Data.ai reported $171 billion of 2023 spending (up 3%), including third-party Android stores in China. Sensor Tower then reported $150 billion on iOS and Google Play for 2024 (up 13%, downloads down 1.0% to 136 billion) and $167 billion for 2025, with time in apps up 3.8% to 5.3 trillion hours.

Key Factors Driving Mobile App Market Growth

Monetization beats installs. With downloads flat, publishers are earning more per user through subscriptions, premium tiers and new revenue models.

Attention. Users spent 5.3 trillion hours in apps in 2025, about 3.6 hours per day.

Subscriptions. Fortune Business Insights projects its subscription segment to grow at 17.4% CAGR, faster than its overall market. This is a vendor forecast, not a measurement.

Generative AI. AI app downloads doubled to 3.8 billion in 2025 and in-app revenue nearly tripled to more than $5 billion.

Connectivity and incomes. Grand View Research cites lower internet costs, smartphone adoption and rising disposable income.

Apps as commerce rails. An Apple-commissioned study estimated $1.3 trillion in App Store ecosystem billings and sales in 2024, of which $131 billion was digital goods and over $1 trillion physical goods. It is a broader measure, not comparable with consumer spending.

Mobile App Market Growth by Region

Regional answers depend on the metric.

Downloads (2025): India, the United States and Brazil led.

Revenue: The US led with nearly $60 billion in consumer spending. China ranked second at $22.1 billion, but Sensor Tower counts only iOS there, so that figure understates the real total.

Time spent: India was first, Indonesia second and the US third.

Analyst revenue shares: Fortune Business Insights credits Asia Pacific with 52.9% in 2025, an older Grand View edition gave it over 32% for 2023, and Growth Market Reports puts North America near 23.5% (about $56.8 billion). The wide spread reflects differing definitions.

Forecast growth: In a forecast made around 2024, Sensor Tower and data.ai expected the US, China, Japan and South Korea to make up about two-thirds of consumer spend in 2030, while Central America, South America and Africa posted the highest seven-year growth rates (12.0%, 10.9% and 10.8% CAGR).

Asia Pacific is the largest region in most analyst reports, while emerging markets show the fastest growth. In generative AI apps, Asia's downloads rose 80% from the second half of 2024 to the first half of 2025, ahead of Europe (51%) and North America (39%).

Fast-Growing Mobile App Categories

Generative AI: the second-largest subgenre by downloads in 2025, behind social media, with ChatGPT alone generating about $3.4 billion in in-app revenue.

Social media, streaming and dating: the biggest in-app revenue sources among non-game apps in 2025.

Short-form drama apps: the fastest-growing by downloads, up 278%.

Credit and lending: downloads up 18%, even as investing and crypto apps declined.

Health and fitness: 3.6 billion downloads in 2024, with medical tracking apps up 43%.

Food and drink: downloads up 8.5% in 2024 as brands built apps into the buying process.

Games are tracked separately: about $81 billion of spend in 2024 (up 4%), and game downloads fell 7.2% to 50.4 billion in 2025 per a summary of Sensor Tower's 2026 data. Grand View Research still gives gaming the largest share (over 40% in 2023) of its market, a reminder that definitions change the ranking.

Emerging Mobile App Market Trends

AI moves from feature to default. Sensor Tower says more than 200,000 apps now mention AI, on track for roughly 10 billion downloads in the first half of 2026 (up 25%). It expects AI app in-app revenue to pass $4 billion in that half-year.

Changing platform economics. On August 18, 2026, Apple announced EU terms effective October 1, 2026: 5% on digital transactions in apps distributed via alternative marketplaces or the web, 26% for App Store apps using Apple's payments and 20% with alternative payment processing. This follows a €500 million Digital Markets Act fine in April 2025. The terms apply to the EU only; Apple's US fee dispute is still being litigated.

Digital fatigue. Sensor Tower noted rising engagement fatigue in streaming and growth in apps that connect to real-world experiences such as fitness, grocery and restaurants.

Challenges Facing the Global Mobile App Industry

Saturated acquisition. Flat downloads make acquisition costlier and retention vital.

Platform dependence and regulatory uncertainty. Commission structures now differ by region and are still shifting.

Concentration in AI. OpenAI and DeepSeek accounted for nearly half of generative AI downloads in 2025.

Forecast risk. Sensor Tower's 2021 forecast of $270 billion for 2025 consumer spending compares with $167 billion reported. Methodology may explain part of the gap, but forecasts remain assumptions.

Inconsistent data. Market sizes for the same year differ by more than $50 billion between publishers.

Future Outlook for the Next 5–10 Years

Mobile application market forecast: what the numbers say

Research-firm forecasts imply roughly $726 billion to $1.2 trillion by 2033–2035, depending on definition and horizon. Endpoints cannot be averaged. A cautious reading: every publisher expects double-digit annual growth, but none agree on the base.

Future of mobile applications: where opportunity sits

AI-native subscription apps with clear utility, not novelty.

Emerging markets, where download growth and ad-supported models remain strong.

Web-to-app and alternative payments, which may improve margins where regulation allows them.

Vertical apps in finance, health and local services that tie digital to real-world use.

Investors should track consumer spending, time spent, and retention rather than headline market-size claims; developers should favor engagement depth and monetization over install volume. None of these projections are guarantees.
