An in-app purchase is any digital transaction a user makes inside a mobile app.

Instead of paying upfront to download, users get the app for free and buy features, content, or subscriptions from within it.

It's the dominant monetization model in mobile, driving over $167 billion in global revenue in 2025.

This guide breaks down how in-app purchases work, the four types, what app stores charge, and how to optimize them for better conversion.

Key takeaways

• In-app purchases (IAPs) let users buy digital goods, features, or subscriptions inside an app.
• There are four IAP types: auto-renewable subscriptions, non-renewing subscriptions, consumables, and non-consumables.
• Apple and Google charge 15-30% commission on every in-app purchase.
• IAPs drove $167 billion in global revenue in 2025, roughly half of all app earnings.
• How you present purchases matters as much as what you sell. Purchasely helps teams optimize that experience. See how it works.

What is an in-app purchase?

An in-app purchase (IAP) is any transaction a user completes directly inside a mobile app to buy digital goods, features, content, or services. It's essentially an upsell from a free (or low-cost) download.

You've likely seen the label before. On the App Store, it says "In-App Purchases" near the Get button. On Google Play, you'll see "Offers in-app purchases" below the app name.

So why does this matter for app teams? Because in-app purchases are how most apps make money. According to industry data, IAPs account for roughly 50% of all mobile app revenue. About 95% of apps on both stores are free to download, which means the real monetization happens after the install.

Did you know? In 2025, global IAP revenue hit $167 billion, with non-gaming apps surpassing gaming revenue for the first time.

What are the four types of in-app purchases?

Apple and Google categorize in-app purchases into four types. The distinction matters because each one suits a different app monetization strategy.

Auto-renewable subscriptions

Users pay on a recurring schedule (weekly, monthly, or annually) for ongoing access to premium features or content. The subscription renews automatically unless the user cancels.

This is the most common IAP type for content and service apps. Examples include:

• Spotify Premium (music streaming)
• ChatGPT Plus (AI assistant)
• Strava (fitness tracking)
• Netflix (video streaming)

If your app delivers ongoing value that users want continuous access to, auto-renewable subscriptions are typically the strongest revenue model.

Non-renewing subscriptions

These work like auto-renewable subscriptions, but they don't renew automatically. When the period ends, the user has to purchase again manually.

Less common, but useful in specific contexts:

• A sports app selling a single-season pass
• An education platform offering fixed-term course access
• A news app with a quarterly access package

Some users prefer this because they don't worry about forgetting to cancel.

Consumables

Consumable purchases are items that get used up and can be bought again. Once used, they're gone. Users need to repurchase if they want more.

Common examples include:

• Coins and gems in games (Candy Crush, Clash of Clans)
• Swipes and boosts in dating apps (Tinder, Bumble)
• Credits or exports in design and productivity tools (Canva)

This creates a repeat-purchase cycle that can drive strong revenue when tied to a well-designed in-app experience.

Non-consumables

Non-consumable purchases are one-time transactions that give permanent access. Once bought, they don't expire and don't need repurchasing.

Common examples include:

• Ad removal
• Premium photo filters or editing tools
• Lifetime feature unlocks
• Extra levels in a game

Because non-consumables can only be sold once per user, they tend to be priced higher than consumables.

Good to know: Non-consumable purchases can be restored if a user switches devices or reinstalls the app. Consumables typically can't.

How do in-app purchases work?

From the user's perspective, it's simple:

1. Tap a "buy" or "subscribe" button inside the app
2. Authenticate the purchase (Face ID, Touch ID, or password)
3. The content or feature unlocks almost instantly

Payment comes from whatever method the user has on file with Apple or Google. That could be a credit card, digital wallet, or carrier billing.

Behind the scenes, the app communicates with StoreKit (iOS) or Google Play Billing (Android). These SDKs handle payment processing, receipt validation, and entitlement delivery. The app store manages global payment infrastructure, fraud prevention, tax calculation, and currency conversion.

For app teams, this means two things. The payment infrastructure is handled for you. But you pay a commission to Apple or Google for that convenience.

Tip: If you're running a subscription app, make sure your app handles failed payments, grace periods, and subscription downgrades. These details directly affect retention and revenue.

In-app purchase examples by industry

In-app purchases look different depending on the app category. Here's how the most successful apps use them across key verticals.

• Gaming is the original IAP powerhouse. Free-to-play games like Honor of Kings ($1.2B in 2025), Monopoly GO! ($1.58B), and Candy Crush Saga drive billions through virtual currency, power-ups, and season passes.
• Streaming and media apps rely on auto-renewable subscriptions. YouTube alone generated over $2 billion in subscription revenue in 2025. Disney+, Netflix, and Peacock follow the same model.
• Health and fitness apps like MyFitnessPal, Strava, and Calm offer premium plans, personalized coaching, and meditation libraries behind a subscription paywall. The health app market is projected to reach $14.7 billion by 2030.
• Dating apps use a mix of subscriptions and consumables. Tinder earned $1.2 billion in 2025 through Gold/Platinum subscriptions plus consumable boosts and super likes.
• AI apps are the fastest-growing IAP category. ChatGPT reached over $2 billion in 2025, and the broader GenAI app segment nearly tripled its revenue year-over-year.
• Education apps like Duolingo use subscriptions to unlock advanced lessons, remove ads, and add features like unlimited hearts.

Key takeaway: The most successful apps don't rely on a single IAP type. They combine subscriptions with consumables or non-consumables to capture value across different user segments and moments.

How much do app stores charge for in-app purchases?

Both Apple and Google take a percentage of every in-app purchase.

Here's the fee structure in 2026:

• Standard commission: 30% on the Apple App Store, 30% on Google Play.
• Small business rate (under $1M/year): 15% on both stores.
• Subscription rate (after year 1): 15% on both stores.
• Physical goods/services: no commission on either store.

These fees only apply to digital goods and services sold inside the app. If your app sells physical products (like an e-commerce store), you use your own payment processor and owe no commission.

Good to know: The EU's Digital Markets Act is changing the rules. Apple now allows third-party app stores and alternative payment methods in the EU, with reduced commission rates. App teams with a large European user base should monitor this closely.

What's the difference between in-app purchases and subscriptions?

This is one of the most common points of confusion. Technically, subscriptions are a type of in-app purchase. But in practice, the terms usually mean different things:

• "In-app purchase" typically refers to one-time transactions (buying coins, removing ads, unlocking a feature)
• "Subscription" means recurring payments for ongoing access

The distinction matters for your app pricing strategy. Subscriptions generate predictable, recurring revenue and tend to drive higher lifetime value. One-time purchases can deliver quick revenue but don't compound the same way.

Most successful apps in 2026 use a hybrid approach: a core subscription for ongoing access, supplemented by one-time purchases for specific features or consumable items.

Did you know? Purchasely works with hundreds of subscription apps to optimize their in-app experience.

Benefits and challenges of in-app purchases

In-app purchases are the most popular monetization model for a reason.

But they come with trade-offs that every app team should understand before deciding how to structure their pricing.

Why IAPs work:

• The freemium model removes download barriers, so anyone can try your app
• App store checkout is familiar and frictionless, reducing payment anxiety
• IAP behavior data tells you exactly what users value and what they'll pay for
• Once a user pays even a small amount, they're more likely to stay engaged

Where IAPs get tricky:

• Only about 1-2% of free users make a purchase, so volume and optimization matter
• App store commissions (15-30%) take a meaningful cut of every transaction
• Platform rules can change, and you're dependent on Apple/Google for payment infrastructure
• Balancing free vs. paid content is an ongoing challenge. Push too hard and you erode trust

Key takeaway: The apps that succeed with IAPs aren't just building great products. They're optimizing the entire in-app experience, from onboarding to paywall to retention.

How to optimize in-app purchases for better conversion

Most guides stop at explaining what in-app purchases are. But the way you present and optimize the purchase experience has a massive impact on revenue. Here's what the best-performing apps focus on.

Design paywalls that convert

Your paywall is the moment of truth. It's where free users decide whether to pay. The best apps don't use a single static paywall. They test multiple versions, personalize based on user segments, and iterate constantly.

Key elements that affect paywall conversion:

• Plan presentation and pricing anchoring (showing annual vs. monthly)
• Benefit-driven copy that answers "why should I pay?"
• Social proof (ratings, testimonial snippets, user counts)
• Trial transparency (clearly explaining what happens when the trial ends)

With Purchasely's Screen Composer, teams can design and deploy native paywalls without code or app store releases. Test a new variant today, see results tomorrow.

Personalize the offer

Not every user responds to the same offer. A first-time user might need a free trial. A returning user might respond to a discounted annual plan. A power user might convert on a premium tier.

Audience-based personalization lets you show different paywalls to different segments based on behavior, lifecycle stage, geography, or custom attributes. The more relevant the offer, the higher the conversion rate.

Test everything

Top subscription apps treat their IAP experience as a product in itself. They A/B test pricing, trial lengths, paywall designs, copy, and placement. Small changes can move conversion significantly.

What to test:

• Pricing (monthly vs. annual default, price points)
• Trial length (3-day vs. 7-day vs. 14-day)
• Paywall design (layout, imagery, copy)
• Placement (after onboarding vs. after a key action vs. on feature tap)

Connect onboarding to monetization

The path from first open to first purchase should feel seamless. If your onboarding flow demonstrates value clearly and quickly, users arrive at the paywall already understanding why the app is worth paying for.

Purchasely's Flows let teams build multi-step journeys connecting onboarding, feature discovery, quizzes, and paywalls into a single personalized experience. You can create paths based on user responses, so each user gets a journey tailored to their intent.

Reduce friction at the point of purchase

Every extra step between "I want this" and "I bought it" costs conversions. Ways to reduce friction:

• Enable native payment methods (Apple Pay, Google Pay) for one-tap purchases
• Use deferred paywalls that appear after value is demonstrated
• Be transparent about pricing and cancellation to build trust
• Minimize required steps between tapping "subscribe" and completing checkout

Final thoughts

In-app purchases are the foundation of how most apps generate revenue in 2026.

Understanding the types, mechanics, and fee structures gives you the baseline. But the real opportunity is in optimizing the experience around those purchases.

The apps that grow fastest treat every in-app interaction as a chance to demonstrate value and convert users at the right moment.

Purchasely helps teams do exactly that, building, testing, and personalizing in-app experiences without engineering bottlenecks. See how it works.

FAQ

How do I implement in-app purchases securely?

Server-side receipt validation is essential. Without it, purchases can be spoofed or pirated. Apple and Google both recommend validating transactions on your backend rather than trusting the client alone. Solutions like Purchasely handle this automatically, managing receipt validation, entitlement delivery, and store communication so your team doesn't have to build and maintain it in-house.

Why does Apple keep rejecting my app for in-app purchase issues?

Guideline 3.1.1 is one of the most common rejection reasons. It typically means your app is either offering digital content without using Apple's payment system, or your paywall doesn't meet Apple's requirements for clarity and transparency. Staying compliant means using the native store payment flow for all digital goods and making subscription terms, pricing, and cancellation options clearly visible.

Can I prevent unauthorized in-app purchases by children?

Yes. Both iOS and Android offer parental controls that require authentication before any purchase. As a developer, you can also reduce risk by designing paywalls that clearly communicate what's being purchased and how much it costs. Apps targeting younger audiences need to comply with COPPA and other child safety regulations, which include restrictions on how purchases are presented.

How do in-app purchase refunds work?

Refunds are handled by Apple and Google, not by the app developer. Users request refunds directly through the App Store or Google Play, and the store decides whether to approve them. As a developer, you can reduce refund requests by setting clear expectations during onboarding, offering free trials so users can evaluate before committing, and making cancellation straightforward. High refund rates can also signal friction in your paywall or pricing strategy.
