What it means
Many apps are free to download but charge for extra value inside the experience, and the payment is separate from installing the app. Apple distinguishes consumables, non-consumables and two subscription types: a consumable can be used up and purchased again, while a non-consumable remains available after one purchase.
A fictional game sells 100 coins that players spend on new levels, and after the coins are used a player may buy more, which is a consumable purchase. A non-consumable might remove advertisements or open a permanent level, and access and restoration rules depend on the store and product setup, so a developer should describe what the buyer receives.
A fictional drawing app charges once for a set of brushes, and users keep the brush pack after closing the app, so the seller treats it differently from a monthly plan. Subscriptions provide access for a period, with some renewing automatically and others ending unless purchased again, so clear renewal terms and cancellation instructions are important; a fictional language app offers a monthly premium plan where the customer pays for ongoing lessons, not ownership of every future course.
In-app purchase does not mean every transaction on a phone, since a delivery app can take payment for a physical meal and that is different from buying digital app content. Google Play's payments guidance distinguishes digital goods and subscriptions from physical goods and services, and store requirements and exceptions can change by market, so check the current platform terms before designing a checkout.
A fictional app sells both virtual recipe lessons and grocery delivery, so the developer checks which checkout rules apply to each offering because one label does not settle both cases. A freemium business uses a free core app to attract users and offers paid extras, and the free experience should still make sense while the premium offer explains the added value.
Useful measures include paying-user conversion, average revenue per paying user and cancellations, with active subscribers tracked separately from one-time buyers, and refunds and failed renewals affect realised revenue. A fictional budget app lets everyone record expenses while a paid tier adds team reports, and another fictional app gets 10,000 installs and 400 first purchases, so its first-purchase conversion is 4% of installs for that period, and repeat purchases need their own measure.
Gross purchase value is not necessarily the developer's cash receipt, because platform fees, taxes, refunds and payment timing may matter, so the store settlement report should be reconciled to the accounts. A fictional developer sees $1,000 in customer purchases and does not book $1,000 as cash received without checking deductions and the transaction's accounting treatment.
A subscription sale is not always immediately earned revenue, since access delivered over months may need revenue recognition across the service period; in a fictional annual plan paid upfront the app must keep providing access for the year, so cash collection and revenue recognition may occur on different schedules. Users should see the price and what they get before agreeing, since hidden costs and confusing renewal screens can hurt trust, and a fictional parent opening a child's game should see clear purchase prompts with controls and explanations of paid items, because the goal is informed choice, not accidental spending.
Purchases also require support processes, because a user may change devices, need access restored or request a refund, and a fictional subscriber who changes phones and cannot see premium access should have the account and entitlement checked before a new purchase is suggested, to avoid charging twice. Price tests should include customer value and retained users, not merely immediate conversion, since a promotion may lift purchases but worsen refunds, and an in-app purchase is a product and a payment journey, so define the entitlement, platform rules and customer promise before treating sales as sustainable income.
In practice
Real-world examples.
Example
A game sells virtual coins that can be used up. A player spends them on new levels and buys another bundle later, so the developer tracks repeat purchases separately from first purchases.
Example
A design app sells a brush pack once, and the buyer keeps access to it permanently. The developer explains clearly on the listing what is included, and support can restore the pack if the user changes devices.
Example
A learning app sells monthly premium access. The renewal date and cancellation steps are shown before the user agrees, and finance tracks active subscribers separately from one-time buyers.
Formula
Calculation
First-purchase conversion = first-time purchasers / eligible app users in the same defined period x 100.
Worked example with fictional figures: an app gets 10,000 installs in a month and 400 of those users make a first purchase. Conversion is 400 / 10,000 x 100 = 4%.
If each first purchase is $5, gross purchase value is 400 x $5 = $2,000. At an illustrative store fee of 15%, the fee is $2,000 x 15% = $300, leaving $1,700 before taxes, refunds and payment timing. The real fee, tax and settlement terms come from the platform agreement and the store report, not from this illustration.Case study
Seen in the real world.
In this fictional case, Cedar Learning launches a free study app with a paid monthly library. It observes many installs but few paid upgrades. The team improves the free-to-paid explanation and checks trial cancellations.
It reviews purchases, refunds and retained subscribers rather than judging success by downloads alone. After two months the team compares cohorts of users who saw the new explanation with those who did not. It also reconciles the store settlement report to its revenue records, so that fees and refunds are visible, and it reports net receipts to the owner instead of gross checkout value.
Watch out
Common mistakes.
- Assuming every mobile payment is a digital in-app purchase.
- Treating gross checkout value as cash received.
- Hiding renewal or entitlement terms.
Questions
People also ask.
Does an in-app purchase always renew?
No. It may be a consumable, one-time item or subscription.
Does buying a physical product in an app count?
It is an app transaction, but store rules distinguish physical goods from digital in-app products.
What is freemium?
A model with a free app experience and optional paid extras.
