Everyone is building apps right now.
Your Twitter feed is full of it. Some 21-year-old vibe-coded a calorie tracker and made $20K in his first month. A guy on Reddit built an AI Excel tool during paternity leave and now makes $220K per month. People who've never written a line of code are shipping real products in a weekend and posting their Stripe dashboards for the world to see.
You've seen all of this. Hard to miss.
But what I kept asking myself was: why apps? Why not a website? Why not a SaaS dashboard? Why not a blog, a newsletter, a course, an agency? There are a hundred ways to build something online.
Why are so many people converging on the same answer right now?
So I did what an entrepreneur with experience does: went deep on it. Pulled some market data and VC funding trends. Well, the truth is: even just for iPhone, creating an app is the single best path for someone with a day job to build real recurring income on the side. Not someday. Now.
This is what I found.
The amount of money flowing through the App Store is absurd
Consumers spent $156 billion on mobile apps in 2025. This is 21% from the year before. iOS alone accounted for $117.6 billion, it is 75% of the market 🤪.
And for the first time ever, non-game apps made more money than games. Health apps, productivity tools, finance apps, AI utilities. That whole category hit $82.6 billion, growing 33.9% in a single year. Games brought in $72.2 billion.

Why does that matter for you? Because non-game categories are exactly where a solo builder competes.
You're not going up against Epic Games. You're going against other small teams building focused tools that solve one specific problem. And that market just grew by a third in twelve months.
iOS is where the money is.
It makes more than double what Google Play makes, even though it has fewer downloads. iOS users spend 2.1x more per app. If you're building a subscription app and picking one platform, it's iPhone. Always.
Now you might think "okay but the top of the charts is all TikTok and YouTube, how does any of this help me?" Fair. Calm down! You and I aren't competing with that.
We don't have to. An app ranked around #500 on the grossing chart earns roughly $76,000 per month. That's $912K a year. You don't need the next TikTok. You need one focused app somewhere in the middle of a $156 billion market.

Note: These are baseline estimates before category multipliers are applied. Actual revenue varies significantly by category — Games apps at the same rank will earn substantially more than Reference apps, for example. See the category breakdown below.
And one more thing. Only about 4% of apps worldwide use subscription models. But that 4% captures 45% of all app revenue. The average subscription price is $7.93 per month. Subscriptions are massively underused and massively profitable. The people who get this model right are playing a completely different game.
Remember when kids were becoming millionaires from apps?
Remember 2008, 2009, when every magazine and news site had a story about some random person who built a simple iPhone app and made a fortune? A teenager making a million dollars. A guy who built an app in his spare time and quit his job three months later. It felt like this wild moment where anyone could strike gold.
That was real. The App Store launched July 10, 2008 with 500 apps. Ten million downloads in the first three days. A billion downloads in nine months. Jobs had actually fought against letting third-party developers on the iPhone. He lost that argument, and it became the biggest wealth-creation platform for regular people since the internet.
Steve Demeter, 29, designed ATM software for a living. Built a puzzle game called Trism in his spare time. Made $250,000 in profit in his first two months.
Ethan Nicholas, engineer at Sun Microsystems, taught himself iPhone development while holding his baby on his lap. Built iShoot. Made $37,000 in a single day when it hit #1. Over $600,000 in one month.

IMPORTANT: $600,000 in 2009 would be equivalent in purchasing power to approximately $913,930 in 2026
Joel Comm released iFart on Christmas Day 2008. An app that made fart sounds. That was the entire product. #1 for 23 straight days. $10,000 to $13,000 per day. Close to $1 million total. Featured on The Daily Show. A fart app.
Dong Nguyen built Flappy Bird in a few days. Simplest game imaginable. Sat in the store doing nothing for eight months. Then it went viral, started making $50,000 per day from ads, hit #1 in 53 countries. Nguyen pulled it because he felt guilty about how addictive it was. Phones with Flappy Bird installed started selling on eBay for thousands.
Nick D'Aloisio started building a news app at 15. Sold it to Yahoo at 17 for $30 million.
Rovio was nearly bankrupt after 51 failed games. Game 52 was Angry Birds. Three billion downloads. Acquired by Sega for $776 million.
Apple ran "There's an App for That" in 2009 and that was the moment. By 2013 they'd paid developers $10 billion. By 2025, $320 billion.
Then the store grew from 500 apps to 2 million, discovery became impossible, and the gold rush faded.
But here's the thing. The economics didn't fade. They got way bigger. The apps that make money today make more money than anything from 2009. What faded was the accessibility. Building an app became expensive and technical again, so regular people stopped trying.
Until now.
The entire VC world is looking the other direction
"The stone the builders rejected has become the cornerstone."
This is the piece I believe people are missing. And it's the real reason the window is open and why it is a trending money machine now.
Consumer investment now accounts for less than 7% of total venture capital. Down from 30% a decade ago. Among the top 100 most active VC firms, consumer was just 6% of their investments in 2024. Half of what it was two years before.

Source: PitchBook Data, Inc. and SVB analysis.
Direct-to-consumer venture funding dropped 97% from the 2021 peak.
Ninety-seven percent.
Y Combinator's Winter 2026 batch was 64% B2B and only about 5% consumer. The ratio went from 2:1 a decade ago to nearly 10:1 today. Every founder, every dollar, every piece of infrastructure in Silicon Valley is pointed at selling software to companies.
Meanwhile, consumer spending is two-thirds of the U.S. economy. People spend $156 billion a year on apps. The demand is exploding. The funded competition has vanished.
Brian Chesky said it on TBPN earlier this year. He pointed out that 87% of YC companies are enterprise. Then said:
"Enterprise is awesome... but the biggest prize is consumer. That is what's going to reach daily life for billions of people."
Chesky knows what he's talking about. Multiple VCs rejected Airbnb because the market "didn't look big enough."
Right now the window is open. The institutional money is all in the B2B room fighting over enterprise deals.
The consumer room is nearly empty. And the money is on the table.
People with zero experience are already making serious money
Blake Anderson. Twenty-three. No coding background. Built apps with ChatGPT. His attractiveness-rating app Umax hit $500,000 per month at peak. His calorie tracker Cal AI reached $3+ million per month.
His playbook is almost stupidly simple: spot trending niches on TikTok, build a simple app solving one problem, pay micro-influencers $50 each to promote it.
Pieter Levels earns $250,000+ per month across Photo AI, Nomad List, Interior AI. Zero employees. 90%+ margins.
Danny Postma built HeadshotPro, an AI headshot tool. $300,000 per month. Solo. Marc Lou made over $1 million in 2025. Also solo.
But the one I keep thinking about is David Bressler. He built Formula Bot, an AI Excel formula generator, during paternity leave. Zero coding experience. Used Bubble.io. Invested $0. One Reddit post in r/Excel brought 100,000 visitors overnight. Hit $220,000 per month in recurring revenue. 5,000 subscribers at $6.99/month. 90%+ margins. Turned down Microsoft and Sequoia.
Zero coding. Zero investment. One Reddit post. $220,000 per month.
On the more accessible end, an indie developer named Max went from $130 to $25,000 MRR by building a portfolio of 30+ small mobile apps.
James Fleischmann turned a failed app into a 30-app portfolio earning $22,000 per month by targeting App Store keywords with high search volume and low competition.
That portfolio approach matters. You don't need one massive hit. Multiple small apps in related niches compound together, like rental properties. Each one is modest on its own. Together they add up.
And subscription revenue stacks. RevenueCat data shows apps launched before 2020 still generate 69% of all subscription revenue today. What you build now keeps paying.

Despite a 7× surge in new app launches since 2022, apps launched before 2020 still account for nearly 70 cents of every dollar generated. Apps launched in 2025 or later (aka, the vibe coding era) account for just 3%.
How to validate an idea without building anything
If you're convinced that apps are the move, the next question is: how do you make sure you pick the right one?
Here's how I'd do it. Takes a few hours. No code. No money.
And the first thing to understand is this: competition is good news. If competitors exist and make money, the market is proven. Facebook wasn't the first social network. Google wasn't the first search engine. You don't need a new idea. You need a better version of something people already pay for.
Search the App Store for your problem. Download the top 5 to 10 competitors. Screenshot their onboarding, features, and pricing. Check rating counts. Multiply the number of ratings by 40 to 80 and you get a rough download estimate. Apps with 1,000 to 50,000 ratings are the sweet spot. Proven demand, still beatable.
Read the 1-star and 3-star reviews. "This app is great but it lacks X." "I wish it did Y." Those complaints are literally customers describing the product you should build.
Check social media. Are TikTok and Instagram creators making content about this problem? If yes, there's demand and there's a distribution channel. Those same creators will promote your app later for $50 to $150. Check Reddit for complaints about existing solutions. One good post in the right subreddit can change everything. That's exactly how Bressler's Formula Bot took off.
Verify people pay. Check competitor pricing on the App Store. If they charge $9.99 to $49.99 per year and have thousands of subscribers, willingness to pay is confirmed. Browse Acquire.com and Flippa to see real apps for sale with verified revenue. Marc Lou's TrustMRR shows Stripe-verified numbers.
If you want extra confidence, run a smoke test. Simple landing page. Little bit of traffic from a social post or Reddit. If 50 people give you their email, you have something. If they don't, pivot. Dropbox and Robinhood both started this way.
Finding it difficult to choose a niche, well, here is a battle tested list of niches that is present in every country, every time in history.

If your niche passes these steps, you've validated the idea. Zero dollars spent. Zero code written. Real evidence that people want what you're about to build.
The honest part
I'm not going to pretend this is easy or guaranteed. The app economy is brutally unequal.
The top 1% of publishers generate 91% of revenue.
Only about 5% of new subscription apps ever reach $10,000 in total revenue.
The median first app will probably make less than $500.
That's real. I'm not going to sugarcoat it.
But that median describes the builder who doesn't validate, doesn't target a painkiller, doesn't study competitors, doesn't use subscriptions, and doesn't ship fast.
What makes right now different is that everything is pushing the same direction at once. Consumer spending is growing fast. VC money for consumer is at historic lows, which means less funded competition. AI tools cut the cost of building by 90%. Subscriptions compound month over month. And the big players are all looking the other way, obsessed with enterprise.
That convergence won't last forever. The VCs will come back. a16z already raised $1.7 billion for it. When the money floods back in, the window for bootstrapped builders shrinks.
The 2008 gold rush needed coding skills, luck, and perfect timing. This one needs taste, speed, and the willingness to ship.
The tools handle the rest.
So. You've seen the numbers. $156 billion in consumer spending. Less than 7% of VC attention. AI tools that turned a $150,000 project into a weekend build. Solo builders making $10K, $50K, $200K per month from apps they made alone.
The data isn't the hard part. The hard part is what you do with it on Monday morning.
Most people will read this, feel a jolt, and go back to their inbox.
This article will still be here when the next round of layoffs hits and the jolt comes back sharper.
But if you're reading this and already thinking "which painkiller niche am I going after"... you're who I built this for.
This is The Billion Person. Every week I break down one playbook, one case study, or one thing you can steal and use today. No AI tool roundups. No industry commentary. Just the path from $0 to $10K/mo in recurring revenue using the current available skills with AI, from someone who's already built and sold companies and is doing it again right now.
Do it this week: validate your app idea in 48 hours without writing a line of code or spending a dollar. The step-by-step process I told here. Then, come back with your doubts, you can do it this year. You can do it now!
See you next week. Go ship.
