In-App Purchases (IAP) are a method of App Monetization 应用商业化 where something can be bought within a mobile app. This is any fee paid to the app developer in addition to the cost of downloading an app.
How can IAPs can be implemented within my app? #
There are different types of IAPs that mobile developers can implement within the mobile app:
- Consumable: This is the most common type of IAP, and is often used in gaming apps. The user pays for a specific item and uses it, after which this item is depleted from the user’s account and a new purchase is made.
- Non-Consumable: With this kind of IAP, certain mobile app features and products can be purchased once, but can be used repeatedly without depleting. An example for this is access to premium features or a new photo filter available for the user account.
- Subscriptions: This type of IAP provides users with continued access to app features, products or services. The user is charged at regular intervals (weekly / monthy / annually) until they choose to cancel their subscription. There are, however, some non-renewing subscriptions as well, which are typically for a specific season or a limited period of time.
What are the most important IAP metrics? #
Some IAP metrics can give you valuable insights into how your app is performing are:
- Customer Lifetime Value (LTV) for e.g. X-day IAP LTV/user
- Average Revenue per Paying User (ARPU)
- Daily Active Users (DAU 日活跃用户)
How to track IAP #
At Tenjin, you can measure your IAP revenue by sending the receipt data through the SDK (or S2S). It’s very simple to integrate this event, and you can find the documentation with instructions for this 这里. With Tenjin, you can also track fraudulent purchases separately in your app, and this data is available on the Tenjin dashboard.
What is IAP revenue per DAU? #
IAP revenue per DAU is the average amount of in-app purchase revenue per daily active user.
How is IAP revenue per DAU calculated? #
At Tenjin, we calculate this using the following formula:
IAP Revenue / Number of users
