A consumable In-App Purchase must be purchased every time the user downloads it. One-time services, such as fish food in a fishing app, are usually implemented as consumables.
Non-consumable In-App Purchases only need to be purchased once by users. Services that do not expire or decrease with use are usually implemented as non-consumables, such as new race tracks for a game app.
- Automatically Renewable Subscriptions
Automatically renewable subscriptions allow the user to purchase updating and dynamic content for a set duration of time. Subscriptions renew automatically unless the user opts out, such as magazine subscriptions.
- Free Subscription
Free subscriptions are a great way for developers to promote their content in Magazines & Newspapers. After a user signs up for a free subscription, it is available on all devices associated with that user’s Apple ID. Free subscriptions don’t expire and can only be offered in apps that are in the Magazines & Newspapers category.
- Non-Renewing Subscription
Non-Renewing Subscriptions allow the sale of services with a limited duration. Non-Renewing Subscriptions must be used for In-App Purchases that offer time-based access to static content. Examples include a one week subscription to voice guidance feature within a navigation app or an annual subscription to online catalog of archived video or audio.
5. After selecting the type, enter a reference name and a product ID for this In-App Purchase.
The Reference name should be Show name and episode number: "Dexter season 1 episode 1".
The Product ID should be the bundle identifier followed by the show name and episode number: "Com.app.Dexter.1.1"
Click on Add Language. Choose the language from the drop down box and give it a display name and description. For example, just the word English for both the display name and description.
