Apple announces contingent pricing for subscriptions →
source: developer.apple.comContingent pricing for subscriptions on the App Store — a new feature that helps you attract and retain subscribers — lets you give customers a discounted subscription price as long as they’re actively subscribed to a different subscription. It can be used for subscriptions from one developer or two different developers. We’re currently piloting this feature and will be onboarding more developers in the coming months. If you’re interested in implementing contingent pricing in your app, you can start planning today and sign up to get notified when more details are available in January.
Parts of this should have been made available to developers years ago. I believe the ability for two separate developer accounts to create discounts together will be especially popular.
