Real apps earn through a handful of models, and the range is enormous: Spotify's freemium-to-subscription engine reportedly generates over $12 billion a year, Flappy Bird's ads reportedly peaked around $50,000 a day, and thousands of solo builders quietly clear a few hundred to a few thousand a month from niche subscription tools. The models are the easy part — subscriptions, ads, in-app purchases, one-time sales, commissions. What separates earners from the graveyard is distribution and retention, and this post is honest about both.
The question behind this question is usually "could that be me?" — so let's answer with real examples across the full range, not just the billion-dollar outliers that make the whole thing feel like a lottery.
The honest range
At the top: Spotify (freemium into subscriptions, reported revenue north of $12B/year), Duolingo (free with ads, Super subscription on top — a public company built on a streak counter). The famous middle: Flappy Bird, whose developer reportedly earned around $50K/day from banner ads at its peak — the canonical proof that free + ads can print money if you have astronomical usage. The realistic bottom, which is most of the market: solo-built niche tools — a habit tracker for climbers, an invoice app for tutors — earning $200 to $5,000/month on subscriptions with a few hundred paying users.
That bottom tier is the interesting one. It's unglamorous, achievable, and it compounds — and it's where almost everyone who "makes money off apps" actually lives.
Real examples, by model
Subscriptions — the dominant model for a reason: predictable, and it survives small user counts. Calm and Headspace built nine-figure businesses on it; a solo builder needs ~150 users at $10/month for a serious side income. The catch is earning the renewal, monthly, forever.
Freemium — Spotify's and Duolingo's engine: free forever for most, paid for the committed few. Conversion rates run low single digits, which is why it needs volume — at 2–5% conversion, a thousand free users is 20–50 paying ones. Fine math for products with organic spread; brutal without it.
Advertising — Flappy Bird's model, and the most misunderstood: ad revenue per user is tiny (a few dollars per thousand impressions), so it only works at huge scale or with unusually high daily usage. If your app idea has 500 users, ads will buy you coffee, not rent.
In-app purchases — the games economy: consumables, cosmetics, level packs. Outside games it works where purchases map to real moments — extra exports, one-off reports, boosts.
One-time purchase — the quiet comeback story. Buy once, own it. Simpler psychology, no churn treadmill; the trade is you must keep finding new buyers forever.
Commissions and transactions — the marketplace model: take a cut of value flowing through. Hardest to start (two-sided cold-start), best economics once running.
Most successful apps stack two: freemium + subscription, free + ads with a paid ad-free tier, marketplace cut + subscription for power sellers.
Why most apps never make a dollar
The uncomfortable stats first: the large majority of apps earn effectively nothing, and it's rarely because the code was bad. Three real causes:
Nobody found it. Distribution isn't a launch task; it's the product's second half. The builders earning quietly all picked niches where they already knew where the users were — a subreddit, a professional community, their own customer base.
Everybody found it once. Downloads without retention monetize nothing; a subscription app with 20% monthly churn is a leaky bucket wearing a business model.
The costs ate the margin. The old version of this failure was $50K of development before the first user. That one, at least, has been largely fixed — which changes who gets to play.
Got an idea? Build it now!
Just start with a simple prompt. No coding required — Greta.sh turns your idea into a working app in minutes.
Getting from idea to something that can earn
The build barrier is the part that collapsed. Describing the app to Greta — including the paid tier, since Stripe payments and auth are built in — gets you a deployed product with a working subscription in days, on the free plan (30 credits a month, 5 a day) to start and $20/month (currently $5 with the welcome offer) after. Which means the modern playbook is validation-first: ship the niche tool this month, charge from week one, and let real payment data tell you whether the idea earns before you invest a year in it. Our monetization models guide goes deeper on choosing the model, and the make-money FAQ in our app-building guide covers the tooling side.
One honest constraint to carry: the model math above doesn't change because building got cheap. Ads still need scale. Freemium still needs volume. If you're one person with a niche, subscriptions or one-time purchase remain the arithmetic that works at small numbers.
FAQ
How much money can you realistically make from an app? The honest distribution: most apps earn nothing; a solo builder with a well-chosen niche and real distribution commonly reaches $200–$5,000/month; venture-scale outcomes are real but rare. The variable is rarely code quality — it's whether you had a path to users.
Which app monetization model makes the most money? At scale, subscriptions and commissions dominate. At small scale, subscriptions and one-time purchases are the only models whose math works with hundreds (not millions) of users.
Can free apps make money? Yes — through ads at large scale, or as the free half of freemium. Flappy Bird's reported $50K/day is the famous ad example, and its lesson cuts both ways: the model worked because usage was extraordinary, not because ads pay well.
How much does it cost to build an app that makes money? Historically five to six figures; with AI app builders, a working product with payments now costs a subscription and your evenings. Our app cost breakdown has current numbers.
