Free apps make money four ways — subscription paywalls, one-time in-app purchases, advertising, and affiliate or referral fees — and in our data the first one carries almost all of the income. Across 96 indexed consumer mobile apps, 34 disclose a clean monthly figure, median $60K/mo, with a full range of $29/mo to $2.2M/mo.
The ranking matters more than the list. Most articles present the four models as equal options; they are not, and treating them as equal is how people spend a year building an ad-supported app that earns like a hobby.

How do free apps make money?
Ranked by how much money they actually carry: recurring subscriptions sold behind an onboarding paywall, then one-time in-app purchases, then advertising, then affiliate and referral fees. In our index of 96 consumer mobile apps, 34 disclose a clean monthly figure and the median is $60K/mo — and the apps at that median are almost all subscription businesses.
The app is free to install. It is not free to use in any way that matters, which is the entire mechanism. Install cost is zero so the funnel can be wide; the money is made on the small percentage who convert on a paywall they saw within sixty seconds.
Whatever the model, the platform takes its cut before you do. Apple publishes its rates in the App Store commission terms and Google publishes its in the Play service fee schedule. Every figure below is post-hype but pre-platform-cut unless the founder said otherwise.
The revenue models, and which one actually carries the money
Subscriptions dominate. Of the disclosing apps in this group, the large figures — $2.2M/mo, $2M/mo, $500K/mo, $440K/mo — are all recurring-revenue businesses, while advertising shows up mostly in the failures section of our index. Here is the honest comparison.
| Model | What it pays | What it costs to run | Where it shows up in our data |
|---|---|---|---|
| Subscription paywall | Highest and recurring — the $60K/mo median and everything above it | Constant install volume, aggressive onboarding, churn management | Gravl $440K/mo, Author AI peak $300K/mo |
| One-time in-app purchase | Real but flat — you re-earn every month from zero | Same acquisition cost, no compounding | Common in portfolio apps |
| Advertising | Lowest per user by a wide margin | Enormous session volume before it means anything | The offerwall audit: about $0.33/hour of user time |
| Affiliate / referral | Narrow but cheap to bolt on | Depends entirely on someone else's product | Rare as a primary model in this group |
The advertising row deserves the honesty. Our audit of offerwall apps measured $0 withdrawn after roughly 40 hours and an earn rate of about $0.33/hour — from the user's side. That number is also a mirror: it tells you what a human hour of attention is worth as advertising inventory, and it is why ad revenue needs scale that a small team will not reach.
What this looks like at real businesses
Named businesses, exact figures, evidence class, and the model each one runs on. Note how the class changes what the number is worth.
- ·[The Viral App Monetization Machine (100 Apps Dissected)](/projects/paywall-machine) — Cal AI and Lerna at $2M/mo each; LazyFit, CoinSnap and Impulse at $700K/mo each. Third-party verified. All subscription paywalls, all small teams.
- ·[App Portfolio Studio Model](/projects/app-studio) — peak $2.2M/mo across 15 apps combined. Founder-reported. Portfolio subscriptions, run by a marketing operator with a technical co-founder.
- ·Gravl — $440K/mo and 70,000+ subscribers. Third-party verified. A subscription fitness app that grew from three people to 13–14.
- ·Author AI — peak $300K/mo, solo. Founder-reported. One person, one subscription product.
- ·[Retake AI Selfie Editor](/projects/retake-ai-selfie-editor) — roughly $2M/mo, creator-relayed via third-party Sensor Tower data. Letterly — $250K/mo, creator-relayed, from a founder with 7 failed attempts over the prior 15 years.
Two more worth knowing: Quitter, a quit-vaping app at roughly $500K/mo (creator-relayed, secondhand from an interview), and the "no-name app army" list running $40K–$300K/mo per app. None of these are household names. That is the point.
How much is each of these numbers actually worth?
The evidence split in this group is 18 third-party verified, 49 founder-reported, 19 creator-relayed, 10 unproven — 70% verified or founder-reported. This is the best-evidenced group we index, and it still means 29 of 96 entries rest on hearsay or nothing.
| Evidence class | Count | What it means |
|---|---|---|
| Third-party verified | 18 | Confirmed outside the founder's own telling |
| Founder-reported | 49 | The operator's own claim |
| Creator-relayed | 19 | Repeated by someone who does not run the business |
| Unproven | 10 | Stated, with nothing behind it |
Gravl's $440K/mo is verified. Retake's roughly $2M/mo is creator-relayed — a real analytics estimate, repeated by someone outside the company. Those are not the same claim, and publishing them in the same breathless list is the standard failure of app-revenue content. We grade every entry before it enters the index; the method is public in how we grade the evidence.
One caveat we will not bury: this index over-represents apps that worked and whose operators then chose to publish numbers. Nobody films a revenue dashboard reading $29/mo. Use the $60K/mo median to judge claims you read elsewhere, not to forecast your own.
Where the money actually comes from, versus where people think it does
Advertising is the over-discussed model and subscriptions are the one quietly producing the $60K/mo median. Ask a room how free apps make money and most people say ads; in our 96-app group, ads appear mainly in the documented failures, while every disclosed figure above $250K/mo comes from recurring subscriptions.
There is a second misplacement. People credit the app and ignore the distribution. NaturalWrite did $100K in 3 months — about $33K/mo average — by validating a keyword TikTok had already proven, shipping in two weeks, and posting one copycat-of-a-hit video a day from a single account. The product was downstream of the traffic.
And the risk nobody prices: platform dependency. Adam Lyttle's portfolio shows $1M+ in lifetime App Store revenue and 2M+ downloads across a sixth consecutive year of building apps (founder-reported) — alongside an account-termination wave that ended other developers with no warning and no second chance. Your developer account is the asset. See the App Economics hub for the full breakdown.
How to use this without fooling yourself
Four things you can check this week. Each one traces back to a number above.
- 1.Choose subscriptions or accept a hobby. If your monetization plan is ads, compare it against $0.33/hour of user attention before you build. The $60K/mo median in this group is a subscription median.
- 2.Read the platform's own fee page before you model anything. Apple's and Google's published schedules set your real gross margin; pair that with the SBA's guide to planning a business for the rest of the plan.
- 3.Prove the traffic before the product. NaturalWrite validated a keyword first and shipped in two weeks. If you cannot name the channel that brings the first 10,000 installs, you do not have a business yet.
- 4.Label every benchmark you collect. Mark it verified, founder-reported, creator-relayed or unproven. Only 18 of 96 entries here are verified — treat the other 78 accordingly, and browse all indexed ideas with the same filter. If apps are not the right vehicle, Free Make Money Online and Ways To Make Money Online For Women cover lower-capital routes.
Frequently asked questions
Do I earn money from creating free mobile apps?
Only if you monetize inside the app. Of 96 indexed consumer mobile apps, 34 disclose a clean monthly figure, median $60K/mo, ranging from $29/mo to $2.2M/mo. That range is the honest answer: the same "free app" label covers businesses earning less than a coffee per month and businesses earning millions.
How can I make $100 a day on my phone?
Not through offerwall apps. Our hour-by-hour audit measured $0 withdrawn after roughly 40 hours and an earn rate of about $0.33/hour, despite FreeCash ranking #2 in the US App Store with 22,000 ratings. Building and selling an app is a different question — 59 of the 96 businesses in this group are one-person operations.
How much money do free apps make?
The median disclosing app in our group of 96 makes $60K/mo. The range runs from $29/mo to $2.2M/mo, so the median describes the middle of a very wide spread, not a typical outcome. Only 34 of 96 disclose anything at all, and 5 entries in this group are documented failures.
How reliable are these how do free mobile apps make money figures?
Mixed, and labelled. This group splits 18 third-party verified, 49 founder-reported, 19 creator-relayed, 10 unproven — 70% verified or founder-reported. Index-wide the split is 57 verified, 184 founder-reported, 121 creator-relayed, 44 unproven across 406 businesses. We publish the class beside every figure.
How many of the 96 indexed businesses actually disclose a monthly number?
Thirty-four. Their median is $60K/mo. That disclosure rate is higher than our index as a whole, where 106 of 406 businesses across 22 countries publish a clean monthly figure at a $27K/mo median, alongside 38 documented failures.
