Differences Between Product Types<br />
Differences Between Product Types<br />
Each product type is designed for a particular use. The behavior of different product types varies in certain<br />
ways, as summarized in Table 1-1 and Table 1-2.<br />

Products that expire or get used up—consumable products, auto-renewable subscriptions, and non-renewing<br />
subscriptions—can be purchased multiple times to get the consumable item again or extend the subscription.<br />
Non-consumable products and free subscriptions unlock content that remains available to the user indefinitely,<br />
so these can only be purchased once.<br />
Consumable products and free subscriptions appear in the receipt after being purchased but are removed the<br />
next time the receipt is updated, as discussed in more detail in “Persisting Using the <strong>App</strong> Receipt” (page 26).<br />
All other types of products have an entry in the receipt that is’t removed.<br />
Consumable products, by their nature, aren’t synced or restored. Users understand that, for example, buying<br />
ten more bubbles on their iPhone doesn’t also give them ten more bubbles on their iPad. All other types of<br />
products are made available across all of the user’s devices. They’re also restored so users can continue to<br />
access their purchased content even after buying a new device. Store Kit handles the syncing and restoring<br />
process for auto-renewable and free subscriptions and for non-consumable products.<br />
