Which app categories are growing fastest now?

Is there actually one fastest-growing app category today?

Generative AI is the fastest-growing major app category overall today, while short-drama apps are growing faster if we look only at downloads.

That distinction is important because app categories can grow in completely different ways. Downloads tell us how quickly new users are arriving. Sessions tell us whether people are coming back. Revenue tells us whether an app is turning attention into money. A category that performs well on all three deserves more weight than one posting a huge percentage on a single metric.

Generative AI currently clears that test better than anything else at meaningful scale. Sensor Tower found that Gen AI app revenue grew 232% year over year between Q2 2025 and Q1 2026, adding more than $4.4 billion of incremental revenue. Its State of AI report then projected global time spent in Gen AI apps at 36 billion hours in H1 2026, versus 17.2 billion a year earlier.

Short drama is the obvious challenger. Global downloads passed 850 million in Q1 2026, up 140% year over year. Revenue reached about $750 million in the same quarter, up 20%. Short drama is arguably the fastest user-acquisition category, but its spending is rising much more slowly than its audience.

For now, we rank Gen AI first overall because its growth is both extremely fast and unusually broad.

Category	Where it is growing fastest	Our read today
Generative AI	Revenue, usage and users	Fastest overall
Short drama	Downloads	Fastest acquisition growth
Finance	Sessions	Strong mature-category growth
Casual gaming	Sessions	Fastest major gaming rebound
Health & fitness	Revenue	Strong monetization growth
Shopping	Regional installs and sessions	Growing, but uneven

Has the whole app market started growing fast again?

The global app market is growing again, but nowhere near fast enough to explain what is happening in AI, short drama or the hottest subcategories.

Adjust measured worldwide app installs up 13% year over year in H1 2026, while sessions increased 5%. Those are healthy numbers for such a mature market. They also give us a useful baseline: anything growing 30%, 50% or 100% is moving far faster than mobile as a whole.

The longer-term picture is even more useful. Sensor Tower estimated roughly $167 billion of global in-app purchase revenue in 2025, up 10.6%, while users spent 5.3 trillion hours in apps. Non-game app spending grew 21% and overtook game spending for the first time.

Downloads, however, barely moved during 2025. More money and more engagement are coming from roughly the same enormous installed base.

The breakout categories really are breakouts. Their growth cannot be explained by a rising mobile tide.

Are generative AI apps still the biggest growth story?

Yes. Generative AI is still producing the strongest mix of revenue growth, usage growth and user growth of any large app category we can find.

Sensor Tower measured Gen AI mobile revenue rising from less than $60 million in Q1 2023 to around $1.9 billion in Q1 2026. That is more than 32 times larger in three years.

The latest usage numbers are just as striking. Sensor Tower projected 36 billion hours spent in Gen AI apps during H1 2026, more than twice the 17.2 billion recorded a year earlier. AI-app in-app purchase revenue was also on track to exceed $4 billion during the half, 36% above the previous six months.

This is happening after AI has already reached mainstream scale. ChatGPT became the first AI assistant to pass one billion monthly mobile users, while Gemini and Claude were also increasing their usage intensity. Sensor Tower measured Gemini at roughly 100 minutes per monthly user and Claude at roughly 120 minutes, both sharply higher than their earlier levels.

The unusual part is the combination. A young category can easily double from a tiny base. Gen AI is still growing at those kinds of rates after becoming one of the largest new consumer-software markets on mobile.

Are short-drama apps growing faster than AI apps?

Short-drama apps are growing faster than AI in downloads right now, but AI is still growing much faster in money.

Sensor Tower counted more than 850 million short-drama downloads globally in Q1 2026, a 140% increase from the previous year. Six short-drama apps entered the worldwide top 40 by downloads, and FreeReels alone passed 100 million quarterly installs after growing 123% from the previous quarter.

NetShort was moving even faster, with downloads up 196% quarter over quarter. These are extraordinary numbers for a format that was still relatively niche outside China only a few years ago.

Revenue tells a calmer story. Short-drama in-app spending reached roughly $750 million in Q1, with DramaBox and ReelShort each close to $140 million. Yet category revenue grew about 20% year over year, far below the increase in downloads.

Short drama is adding viewers at a spectacular pace. AI is doing a much better job of turning its additional usage into additional consumer spending.

Is AI app growth still real now that ChatGPT is already huge?

Yes. AI-app growth is still very real, although the next phase is spreading across several products instead of coming almost entirely from ChatGPT.

ChatGPT becoming enormous could have marked the beginning of saturation. Instead, Sensor Tower found that ChatGPT's share of the Gen AI audience fell below 50% as Gemini, Claude and other competitors gained users.

That is a healthy sign for the category. If the leader loses share while total usage keeps rising sharply, competitors are expanding the market rather than simply fighting over a shrinking pool.

We can see that in engagement. Sensor Tower measured ChatGPT at around 215 minutes per user per month, while Gemini and Claude were both increasing time spent rapidly. More than 200,000 apps now mention AI in their store descriptions, and those apps were on track for nearly 10 billion H1 downloads, 25% more than a year earlier.

AI is therefore becoming broader even as the general-assistant market matures. The next wave is showing up in image and video tools, companions, agents, productivity apps, education, health and other vertical products.

Are finance apps quietly becoming one of the fastest-growing mature categories?

Yes. Finance apps are currently one of the clearest examples of an old app category suddenly getting much more usage.

Adjust measured global finance-app installs up only 5% in H1 2026, while sessions jumped 29%. Session growth stayed above 21% every month of the half and reached 36% in March.

That gap between installs and sessions is useful. Finance apps are not depending mainly on millions of first-time downloads. Existing users are opening them more often.

The pattern was already visible before that. Global finance sessions increased 21% in 2025, payment-app sessions rose 22%, and Latin America recorded much faster expansion, with finance installs up 76% and sessions up 57%.

Crypto helped restart some of that activity. Earlier Adjust data showed crypto-app sessions jumping 45% during the recovery in digital-asset markets. But the latest finance growth reaches well beyond crypto: payments, wallets, brokerage and banking are all part of it.

For a mature category, repeated usage growing this quickly is more interesting than a short-lived download spike.

Are casual games actually growing fast again?

Yes. Casual games are having a surprisingly strong engagement rebound right now, even though mobile gaming overall remains a mature market.

Adjust measured global gaming sessions up 6% in H1 2026. Casual-game sessions rose 55%.

Other genres were growing too, but at much lower rates: arcade gained 19%, match games 18%, hyper-casual 17%, sports 15%, hybrid-casual 14% and strategy 10%.

The previous year had already produced some strong genre-level movements. Casual-game installs grew 19%, strategy sessions 57% and hyper-casual sessions 31%. The winners keep changing, which makes the broader “gaming is booming again” claim hard to defend.

Global mobile-game revenue has also looked much flatter than non-game revenue. In India, for example, Sensor Tower measured game revenue rising 10% year over year in Q2 2026 while worldwide gaming revenue fell 6.2% quarter over quarter.

So we put casual gaming high on a list of fast-growing app subcategories today, but gaming as a whole does not belong near the top.

Is health and fitness still a fast-growing app category?

Health and fitness is growing strongly in revenue, although its user base is expanding much more slowly.

Sensor Tower estimated that Health & Fitness apps generated a record $4.5 billion of in-app purchase revenue in 2025, up 13%. Downloads were roughly flat, rising only 0.8% to around 3.96 billion.

Health apps are getting better at monetizing an already-large audience.

RevenueCat's 2026 subscription data backs that up. Health & Fitness had a 6.9% median download-to-trial conversion rate, while median trial-to-paid conversion reached 37.7%, one of the strongest results among the categories it measured. Its best performers converted more than 23% of downloads into trials.

Health apps also fit particularly well with subscription pricing because the underlying jobs recur. People come back for workouts, nutrition tracking, sleep, meditation and coaching instead of completing one task and leaving.

We would therefore call Health & Fitness one of the stronger monetization-growth categories today rather than one of the fastest categories for new-user acquisition.

Are shopping apps growing fast again?

Shopping apps are growing again in several markets, but the global numbers still look modest beside AI, short drama and finance engagement.

Adjust found global e-commerce sessions up 5% in 2025 and marketplace/classified sessions up 7%. Latin America was much stronger, with e-commerce installs rising 17%.

H1 2026 brought another encouraging sign. Install-day engagement improved across every major region Adjust tracks. North America moved from 1.31 sessions on install day to 1.34, APAC from 1.41 to 1.42, Europe from 1.36 to 1.37, MENA from 1.36 to 1.38 and Latin America from 1.38 to 1.40.

India shows how much faster shopping can grow locally. Sensor Tower reported more than 6.6 billion total app downloads in Q2 2026, with e-commerce and quick commerce among the categories pushing acquisition higher. Meesho was the country's most downloaded shopping app, while Blinkit also reached the overall top-download rankings.

We see a healthy shopping market rather than a global breakout. Geography makes the difference here: local commerce can be expanding extremely quickly even while the worldwide category grows at single-digit rates.

Are social media apps still growing fast?

Social media still dominates mobile attention, but it is no longer one of the fastest-growing categories by percentage.

Sensor Tower estimated that users spent close to 2.5 trillion hours in social-media apps during 2025. Gen AI was around 48 billion hours over the same period, so social was still more than 50 times larger.

The trajectories are very different. Gen AI time spent was growing several times over, while social media was adding usage from an already enormous base.

Scale can confuse this comparison. Instagram, TikTok, Facebook and other social platforms remain among the biggest apps on earth. Their sheer size makes another 100% growth year practically impossible.

Social therefore belongs near the top if we rank app categories by total attention. It drops much further down when we rank them by current growth rate.

Does the fastest-growing app category change depending on the country?

Absolutely. AI and short drama are strong globally, but local growth rankings can look completely different once we move from one country to another.

India is the clearest example right now. Sensor Tower measured 6.6 billion app downloads in Q2 2026, the country's highest quarterly level since early 2024, while in-app purchase revenue reached a record $345 million, up 35% year over year.

Gen AI, entertainment, e-commerce and quick commerce were all major contributors. ChatGPT ranked first among non-game apps by downloads, while cumulative short-drama downloads in India passed 800 million. Story TV reached a record monthly audience and became the country's leading short-drama app.

The speed of short-drama adoption there has been extraordinary. In the previous quarter, category downloads had risen 403% year over year. FreeReels had also increased its digital advertising spend more than fivefold while downloads jumped 520% quarter over quarter, showing how aggressive the acquisition race had become.

Latin America produces another mix. Finance and e-commerce have both posted much faster growth there than globally. Southeast Asia has become central to short drama. Mature markets such as the US generate a much larger share of AI and subscription revenue.

Anyone asking which app category is growing fastest therefore needs both a global answer and a geographic one.

Market	Categories standing out now	What is driving the growth
India	Gen AI, short drama, e-commerce, quick commerce	Huge download base plus rising monetization
Southeast Asia	Short drama, commerce	Mobile-first acquisition
Latin America	Finance, e-commerce, short drama	Rapid digital-service adoption
US	Gen AI, subscriptions	High spending per user
Mature global markets	AI, health, productivity	Monetization more than download expansion

Which fast-growing app categories have the best chance of keeping their growth?

Finance looks unusually durable, AI has the biggest upside but a real retention problem, and short drama still has to prove that its huge download growth can turn into equally strong long-term economics.

RevenueCat's subscription data exposes AI's main weakness. AI-powered apps generated 41% more first-year realized lifetime value per payer than non-AI apps, with a median of $30.16 versus $21.37.

People also leave them faster. Monthly AI subscriptions retained 6.1% of subscribers after 12 months, compared with 9.5% for non-AI apps. Annual plans retained 21.1% versus 30.7%. Refund rates were 4.2% for AI apps and 3.5% for non-AI apps.

AI has exceptional monetization at the front of the funnel and weaker loyalty later on. That does not kill the growth story, but it is probably the biggest unresolved question around it.

Short drama faces a different issue. User acquisition has become extremely aggressive. FreeReels' expansion in India, for example, came alongside a more than fivefold increase in digital ad spending. The category can keep growing, but we need to know how much of that audience stays once publishers stop buying growth so heavily.

Finance has a less spectacular but reassuring pattern: sessions are rising much faster than installs. That usually points toward deeper usage among people already acquired.

If we are judging durability rather than raw speed, finance moves up the ranking.

Which fast-growing app categories look best for launching something new?

Vertical AI looks more open than general AI assistants, while health, productivity and creative tools offer better entry points than trying to build another broad chatbot.

The opportunity inside AI is becoming uneven. General AI assistants are already dominated by OpenAI, Google, Anthropic and other companies with huge distribution and compute budgets. ChatGPT's scale makes a direct copycat especially hard to justify.

The picture is much less settled in specialized AI. Sensor Tower has found more fragmentation in AI companions, AI agents, image and video generation and other vertical products. Those markets still allow new apps to reach meaningful scale without first displacing ChatGPT.

RevenueCat's data show where AI is spreading fastest among subscription products. Roughly 61.4% of Photo & Video apps in its dataset use AI, followed by 41.1% of Productivity apps. Penetration is far lower in Business at 19.1%, Travel at 12.3% and Gaming at 6.2%.

Those numbers do not mean Photo & Video is automatically the best market. They show how quickly AI has already become normal there. Less saturated verticals may offer more room if AI creates a clear improvement rather than another generic feature.

Health is particularly interesting because users already pay well for recurring value. Finance can be attractive too, although regulation and trust make it much harder to enter. Short drama offers explosive acquisition potential but requires a continuous content machine and often a large paid-marketing budget.

The better opportunity today is usually a fast-growing behavior inside an existing category, rather than simply choosing the category with the highest headline growth rate.

Which app categories are growing fastest now?

Generative AI is the fastest-growing major app category overall right now, short drama leads on new-user growth, and finance plus casual gaming stand out for engagement.

Gen AI takes the top spot because the category is still growing extremely quickly after reaching serious scale. Revenue, time spent, active users and the number of AI-powered apps are all moving upward together. We rarely see that combination once a consumer-software category is already worth billions of dollars.

Short drama comes second overall and first for acquisition. Its worldwide download growth is extraordinary, especially across India, Southeast Asia and Latin America. The weaker part is monetization: audience growth is currently running far ahead of revenue growth.

Finance deserves more attention than its download numbers suggest. As seen above, installs increased only modestly while sessions grew several times faster. That is the kind of growth we would expect from a category becoming more deeply embedded in people's routines.

Casual gaming is the surprise entry, with session growth far above gaming overall. Health & Fitness follows because users are spending more even though downloads are barely growing. Shopping remains stronger regionally than globally, while social media is simply too mature to match the percentage growth of these newer categories.

So the answer today is fairly clear: Gen AI is growing fastest across the metrics that matter most, while short drama is the category adding users at the most extreme pace.

Rank	App category	Fastest-growing part	Our current judgment
1	Generative AI	Revenue + usage + users	Fastest overall
2	Short drama	Downloads	Fastest audience growth
3	Finance	Sessions	Strongest mature-category engagement growth
4	Casual gaming	Sessions	Strong gaming subcategory rebound
5	Health & fitness	Revenue	Strong monetization growth
6	Shopping	Regional installs and sessions	Fast in selected markets
7	Social media	Absolute usage	Huge, but comparatively mature
