Free apps can make money with affiliate marketing by letting external partners promote the app in exchange for commissions on any revenue those partners generate. This works even if the app itself is completely free to download and use, because the affiliate programme incentivises creators and influencers to drive users toward premium upgrades, in-app purchases, or subscription tiers within the app.
But there is also a second model that works purely for free apps with no paid tier at all: the app can earn affiliate commissions by recommending relevant third-party products or services to its users. Both approaches generate revenue without compromising the free user experience that attracted your audience in the first place.
The Free App Monetisation Challenge
Building a free app is a deliberate choice. You want maximum reach, minimum friction, and the largest possible user base. But free does not pay the bills. The traditional solutions — advertising, freemium upgrades, in-app purchases — each come with trade-offs.
Display ads interrupt the user experience. Banner ads generate fractions of a penny per impression. Interstitial ads frustrate users and drive uninstalls. Even well-implemented ad placements create a tension between revenue and retention.
Freemium models gate features behind a paywall, which works for some categories but alienates users in others. Not every app lends itself to a premium tier. Some apps deliver their full value for free and would lose their appeal if key features were locked.
Affiliate marketing offers a third path that avoids both of these trade-offs.
Model 1: Affiliates Promote Your App
If your free app has any form of monetisation — a premium tier, a subscription option, one-time purchases, or even donations — you can build an affiliate programme around it.
Here is how it works:
- Content creators, bloggers, YouTubers, and community members sign up as affiliates through your signup page.
- Each affiliate receives a unique referral link.
- When someone clicks that link, downloads your app, and eventually makes a purchase, the affiliate earns a commission.
- Commissions are paid in cash through Stripe.
The beauty of this model is that your app remains completely free to download. There is no paywall at the front door. Users discover the app through an affiliate's recommendation, try it for free, and some percentage upgrade on their own terms. You only pay the affiliate when that upgrade happens.
This is particularly powerful for freemium apps. Your free tier does the convincing. The affiliate does the distributing. The premium tier generates the revenue. Everyone wins.
Model 2: Your App Earns Affiliate Commissions
If your app is truly free with no paid features at all, you can still generate revenue by recommending products and services that are relevant to your users.
A fitness tracking app could recommend workout equipment. A recipe app could recommend kitchen tools or ingredient delivery services. A budgeting app could recommend financial products. A language learning app could recommend travel services or textbooks.
The key is relevance. The recommendations must feel like a natural extension of what the user is already doing in your app. If the suggestions are useful, users appreciate them. If they feel forced or irrelevant, users treat them like ads.
This model turns your user base into an asset. The larger your free audience, the more affiliate revenue you can generate, all without ever charging your users a penny.
Why Affiliate Marketing Suits Free Apps Better Than Ads
The comparison with advertising is important because ads are the default monetisation method for most free apps. Here is where affiliate marketing is different:
Revenue per user. A single affiliate-driven subscription or purchase can be worth more than thousands of ad impressions from the same user. If your affiliate programme pays you even a few pounds per conversion, that one conversion is worth more than months of ad revenue from a typical user.
User experience. Affiliate recommendations can be integrated naturally into your app's content and flow. They do not flash, pop up, or interrupt. They sit alongside the content your users are already engaging with.
No advertiser dependency. Ad revenue depends on advertiser budgets, seasonality, and ad network algorithms. Affiliate revenue depends on the value of your recommendations and the size of your audience — factors you control.
No minimum traffic requirements. Most ad networks require significant daily active users before they generate meaningful revenue. Affiliate marketing can generate income from day one, even with a small but engaged user base.
Setting Up an Affiliate Programme for a Free App
The technical implementation is the same whether your app is free, freemium, or paid. With Insert Affiliate, the setup involves three main steps:
Step 1: Integrate the SDK. Insert Affiliate provides SDKs for all major platforms — Swift, Kotlin, React Native, Flutter, Unity, and JavaScript. The SDK handles referral attribution, connecting the affiliate's link to the user's in-app activity.
Step 2: Connect your billing. Whether you use RevenueCat, Adapty, Apphud, Iaptic, direct App Store purchases, direct Google Play purchases, or Stripe, Insert Affiliate integrates with your existing payment infrastructure. You do not need to change how you handle billing.
Step 3: Set your commission structure. Decide whether to offer a flat fee per conversion or a percentage of revenue. Insert Affiliate supports both flat-fee and revenue-share plans. Commissions are paid through Stripe Connect, so affiliates receive real cash payments.
Once the programme is live, affiliates sign up through your signup page, get their referral links, and start promoting your app.
Choosing the Right Commission Structure
For free apps with a premium upgrade, your commission needs to make mathematical sense. Calculate your average revenue per paying user over their lifetime. Then set your commission as a percentage of that revenue that leaves you profitable.
For example, if your average subscriber pays ten pounds per month and stays for eight months, your lifetime value is eighty pounds. Offering a 20 percent commission on first-year revenue means paying up to 24 pounds per acquired customer, giving you a healthy margin.
For free apps earning affiliate commissions from third-party products, the commission rate is set by the partner programme. Your focus should be on maximising conversion rates by ensuring the products you recommend are genuinely relevant to your audience.
Real Revenue From a Free App
Thirty-five percent of apps now combine multiple monetisation strategies, and this number is growing. Affiliate marketing is emerging as one of the most accessible additional streams because it requires no changes to your pricing model, no disruption to the user experience, and no upfront investment.
Whether you use affiliates to promote your app's premium features or you earn commissions by recommending relevant products to your users, the result is the same: real revenue from a free app, paid in cash, with zero risk.
The days of choosing between "charge users" and "show ads" are over. Affiliate marketing gives free apps a third option that aligns the interests of the developer, the user, and the affiliate.
