In-app purchase meaning, in one line: an in-app purchase (IAP) is any payment a user makes inside a mobile app after installing it, for digital content, features, or a subscription. It’s separate from paying to download the app. Apple calls these in-app purchases; Google Play calls them in-app products. If you’ve ever tapped “Buy” on an upgrade, a bundle of coins, or a premium tier inside an app, that was an IAP.
But what does in-app purchase mean for your business? If you run or market a mobile app, IAPs are one of the strongest revenue levers you have. The global IAP market is projected to reach $340.76 billion by 2027, and knowing how to use them is the first step to claiming a share.
This guide covers the in-app purchase definition, the main types of in-app purchases, how they work, and their benefits. You’ll also see how real brands, from Candy Crush to Coursera, use IAPs to drive mobile app monetization, and where Pushwoosh fits in turning those tactics into revenue.
In-app purchase definition: what exactly is IAP?
An in-app purchase (IAP) is any transaction a user makes inside a mobile application after downloading it. This is different from paying to download the app itself: an IAP happens within a free or paid app, letting users buy digital content, features, or services without leaving it.
Here is what an in-app purchase looks like in practice:
- Unlocking premium levels in a puzzle game like Candy Crush Saga.
- Buying virtual currency (gems, coins, crystals) inside apps like Duolingo or Forest.
- Subscribing to premium features, such as ad-free listening on a music streaming app.
That’s the whole of the in-app purchase meaning: a transaction for digital goods or services that happens entirely within an app.
Understanding the in-app purchase meaning matters for app developers and marketers because IAPs are the dominant way free-to-download apps make money, and those apps are the vast majority on both the Apple App Store and Google Play.
What does “Offers In-App Purchases” mean in the app stores?
If you’ve browsed an app’s store listing, you’ve probably seen a note flagging that it sells IAPs. So what does “Offers In-App Purchases” mean in practice? Both stores show it, just in different spots.
On Google Play, the label reads “Offers in-app purchases” and sits right under the app’s name, developer, and age rating. Google Play doesn’t publish the full list of items, but under Additional Information you can see the price range of in-app products.
On the Apple App Store, the “In-App Purchases” message appears next to the Get button (for free apps) or the price (for paid ones). Open the app’s product page, scroll to the Information section, and tap In-App Purchases to see the complete list.
So when someone asks what “Offers In-App Purchases” means, it’s simply the stores telling you, before you download, that the app has optional paid content inside. For a developer, that label is where a prospective user first learns there’s money involved, which makes the in-app experience around it worth getting right.
Types of in-app purchases
Not all in-app purchases are the same. The types of in-app purchases you offer shape your monetization model, user experience, and revenue potential. There are three main categories.
Consumable in-app purchases
Consumable in-app purchases are items used once and then repurchased. They’re the most common type in mobile games and productivity apps.
- Virtual currency: gems in Duolingo, gold bars in Candy Crush Saga.
- Energy or lives refills: extra lives in a puzzle game, fuel in a racing game.
- Temporary boosts: XP boosters, speed-ups, or power-ups that expire after a single use.
Consumables drive repeat purchases, which makes them a reliable source of recurring revenue.
Non-consumable in-app purchases
Non-consumable in-app purchases are items users buy once and keep. They don’t expire or deplete.
- Premium features: removing ads, unlocking a pro camera mode.
- Permanent content: a new character skin, an extra level pack, a theme for a productivity app.
- Digital goods: stickers, filters, or design templates that stay in the user’s account for good.
Non-consumables suit apps that want a clear upgrade path from free to premium.
Subscriptions
In-app subscriptions grant access to content or features for a recurring period, weekly, monthly, or annually.
- Auto-renewable subscriptions: charge the user at the end of each billing cycle (e.g., Spotify Premium, Coursera Plus, Headspace).
- Non-renewing subscriptions: expire after the purchased period and need manual renewal (e.g., a seasonal sports pass, limited-time access to a course catalog).
Subscriptions are the fastest-growing segment of in-app revenue, and they give developers predictable, recurring income.
How do in-app purchases work?
The in-app purchase flow is straightforward:
- User initiates the purchase. They tap a “Buy” or “Subscribe” button inside the app.
- The app store processes the payment. The transaction runs through the platform’s payment gateway, either the Apple App Store or Google Play. The user authenticates (Face ID, fingerprint, or password), and the store processes the payment securely.
- Content is unlocked. Once payment clears, the app delivers the item, feature, or subscription instantly.
Developers integrate IAP functionality with platform-specific SDKs (StoreKit for iOS, Google Play Billing Library for Android). These handle product listings, payment processing, receipt validation, and content delivery, so the developer can focus on the experience rather than the payment plumbing.
The app store takes a commission, typically 15 to 30%, on each transaction. The rest goes to the developer.
Benefits of in-app purchases for app developers and users
Why use in-app purchases? The advantages run to both sides of the transaction.
For app developers
- Diverse monetization: combine consumables, non-consumables, and subscriptions to match your audience and business model.
- Revenue from free apps: the freemium model, free download with optional purchases, is the most profitable distribution strategy in mobile. It lowers the barrier to entry and grows your install base.
- Predictable recurring income: subscriptions give you a steady stream that helps with forecasting and planning.
- Higher CLV: users who buy virtual goods or premium features tend to engage more, stay longer, and spend more over time.
For users
- Try before you buy: the freemium model lets people explore the core app free before paying.
- A better experience: IAPs add personalization, premium content, and convenience, and users pay only for what they value.
- Flexible spending: users control how much they spend and when, from a one-time $0.99 unlock to a monthly subscription.
Apps that cracked the IAP code
Which apps lean on in-app purchases most? Gaming, productivity, education, lifestyle, and shopping, mostly. What’s worth studying isn’t that they sell IAPs, but where and when they ask. Here’s how apps across these categories build IAPs into their monetization while keeping users engaged enough to actually buy.
| Item type | Apps that sell this type of item | App category |
|---|---|---|
| Virtual currency | Duolingo | Education |
| Candy Crush Saga | Puzzle game | |
| Forest | Productivity | |
| Jewels of Rome: Match 3 | Adventure game | |
| Premium Content /Features | Tinder | Lifestyle |
| Etsy | Shopping | |
| Insight Timer | Health & Fitness | |
| Coursera | Education |
Duolingo: cross-channel engagement champion
About 18% of Duolingo’s revenue comes from in-app purchases of gems. Users spend gems on hearts to refill lives, on boosters for extra experience points, and on unlocking challenges like ‘Match Madness’, which are tiered so each level costs progressively more:
Duolingo’s approach
Duolingo works hard across channels to pull users back into the app. Daily engagement builds loyalty, and loyalty leads to more purchases.
- Push notifications
Duolingo’s personalized pushes play on emotion. One might make a humorous appeal to the user’s frustration, say, when they’re about to lose a 41-day streak. Another leans on competition, like when a user slips down the leaderboard:
- In-app messages
In-app messages promoting ‘Friends Quests’ build community and a bit of healthy competition, which keeps users motivated:
- Emails
Duolingo regularly emails users to keep them committed to their language-learning:
Its 40% YoY revenue growth in 2024 says the omnichannel approach, paired with sharp copy, is doing its job.
How to automate user engagement across channels with Pushwoosh
Omnichannel engagement only scales once you automate it. Messaging flows, whether scheduled or triggered by behavior, keep communication timely and relevant, and Pushwoosh Customer Journey Builder is built for exactly that. You can reach users across push, in-app, email, SMS, and WhatsApp from one workflow.
On the canvas, you set how the flow adapts to what users do. If someone opens a push, follow up with an in-app message. If they don’t, send an email instead:

Candy Crush Saga: game in-app monetization classic
In 2012, Riccardo Zacconi and his team launched Candy Crush on a freemium basis. The model was new at the time, and it paid off for years.
By 2023, the game generated over $1.2 billion from in-app purchases. Players across six continents log in daily for a quick unwind and a dopamine hit.
What makes it so durable? Two engagement tactics sit behind the success.
1. Engaging users from the very first tap
Download the game and you’re straight into gameplay, no registration wall in the way. Cutting that friction early keeps people in.
2. Prompting purchases at the right moment
The first purchase prompt shows up only after level 20, roughly 30 minutes in. By then players are usually deep enough in to be tempted by boosters. It’s a textbook mobile game IAP move. The weekly deal sits prominently on screen with a 50% discount tag to catch the eye:
Gardenscapes: dual gameplay, multiple targeted offers and events
Gardenscapes combines match-3 puzzles with a home-renovation storyline, providing players with dual goals that boost session length and spending opportunities. Timed events and themed boosters are targeted to specific segments, such as competitive players or decorators, maximizing conversion.
Forest: turning in-app purchases into real trees
Forest helps people stay off their phones and focused. While you study or spend time with friends, the app grows a tree in real time. Close the app, lose focus, and the tree dies.
Users can buy virtual items like ‘crystals’ or ‘bonus packs’ to unlock premium features, get coin boosters, and add background sounds to focus sessions:
Connecting eco-values with user engagement
Every focus session earns coins, which users can put toward planting real trees. Thanks to that eco-conscious base, the app, with Trees for the Future, has planted over 1.5 million real trees.
Showing focus status through Live Activities
One of the strongest parts of Forest’s engagement is its real-time feedback on a focus session’s progress.
For iOS users, the team uses Live Activities, so people track their session without unlocking the phone. That constant visibility keeps them in the app, and the more attached they get, the more likely they are to buy:
How to use Live Activities to drive more revenue
Live Activities keep users posted on in-app processes and lift the overall experience. Pair them with promotional pushes and you get contextual moments to sell. Forest, for instance, could push an offer to buy crystals right as a user nears the end of a focus session. You can enable Live Activities with the Pushwoosh iOS SDK.
Jewels of Rome: push notifications that promote limited-time offers
In November 2024, Jewels of Rome hit over 5,000 downloads and $200,000 in revenue. A big share came from in-app purchases: boosts, energy refills, and premium currencies.
To promote those items, Jewels of Rome uses push notifications. The example below is built to create urgency and push users to grab the offer while it lasts:
These examples show how good games turn ordinary gameplay moments into revenue.
How to announce limited-time offers with Pushwoosh
Send push notifications at scale to announce new items for purchase. Use the ‘Wait for Trigger’ element in the Customer Journey to check instantly whether a user has bought. If they haven’t, send an automatic push with a limited-time offer:

Tinder: promoting in-app purchases for better matches
Tinder sells popular IAPs that help users stand out:
- Super Likes: triple the chance of matching, which leads to longer conversations.
- Boosts: put a user’s profile at the top in their area for 30 minutes, raising visibility and connections.
Both help users reach the reason they’re on Tinder in the first place: a good match.
Promoting premium features with modal in-apps
Tinder uses modal in-app messages to promote premium features. Because these don’t take over the whole screen, they don’t feel intrusive.
Instead, they nudge users to explore more of the app, which lifts engagement and opens up more spending:
Etsy: in-app personalization that drives sales
Etsy lets users buy gift cards straight from the app, part of a wider push to make Etsy a go-to for gifting. Features like ‘Gift Mode’ and ‘curated gift suggestions’ are there to encourage more gift purchases.
Drive more sales with personalized in-apps
The clever part is the personalization. Etsy’s gift cards can introduce newcomers to the marketplace and turn them into long-term customers. Gift cards also lock in guaranteed sales, since the value is paid upfront whether or not it’s redeemed right away:
How to personalize in-app offers with Pushwoosh
User segmentation is the foundation of personalized experiences. In Pushwoosh you can group users by behavior, purchase history, preferences, funnel stage, location, language, and OS version.
You can also build segments around specific date tags to reach users on key occasions like their birthdays, personalizing the message for the day to lift engagement and in-app sales:

Insight Timer: subtle about in-app donations
On Insight Timer, users can donate to support their teachers’ work. To encourage a regular practice, the app sends personalized pushes. After each session, users rate the experience and get an invitation to donate:
Coursera: upselling to high-value users
On Coursera, users can buy both subscriptions and professional certificates. The certificates work as IAPs for people who’d rather not commit to a full subscription.
Engaging recent course graduates with targeted discounts
Coursera targets users who’ve just finished a course with a $100 discount on the annual subscription. Here’s an upselling email:
