In an article posted to App Store Connect, Apple has detailed how iOS, macOS, and tvOS app developers will soon be able to offer discounted subscriptions to past subscribers in an attempt to win those customers back. 

As with introductory offers for new subscribers, there will be three categories of promotional offers for previous subscribers:

Free 

Customers access your subscription for free for a specific duration — for example, a 30-day trial for a subscription with a standard renewal price of $4.99 per month. 

Pay As You Go 
Customers pay a promotional price for each billing period for a selected duration — for example, $1.99 per month for three months for a subscription with a standard renewal price of $9.99 per month. 

Pay Up Front 
Customers pay a one-time promotional price for a specific duration — for example, $9.99 for the first six months of a subscription with a standard renewal price of $39.99 per year.

Developers will be able to offer up to 10 different promotions at once to test the waters. 

The promotional offers will also be available to existing subscribers, allowing developers to both retain and win back subscribers. A customer who has yet to subscribe to an app will not have access to the promotional offers, but may be presented with an introductory offer if the developer offers one. 

Using receipt validation, developers will be able to identify subscribers who have turned off auto-renewal so that they can act quickly with a promotional offer in an attempt to win them back before the end of their current subscription period. 

Once the promotional period ends, the subscription auto-renews at the standard price, according to Apple. 

Promotional offers for previous and existing subscribers will be available in iOS 12.2, macOS Mojave 10.14.4, and tvOS 12.2 and later. Developers can get ready now by creating offers in App Store Connect and by downloading the Xcode 10.2 beta and implementing the new StoreKit APIs into their apps. 

Apple first announced this change in its iOS 12.2 beta release notes. More information is available on the Apple Developer website.
