Programs will be able to use three discount models that allow customers to receive a free subscription for a certain period, pay a promotional price for each billing period, or pay a one-time promotional price to their own Apple Music subscribers. Developers will also be able to offer up to 1
0 active test subscription proposals that work best. This extra flexibility will be available with the latest beta versions of iOS 12.2, macOS 10.14.4 and tvOS 12.2, using the StoreKit API. Although now it's only in beta, these changes are likely to become available to everyone when these software updates are completely released. Apple for the first year has a 30 percent reduction in app revenue, but programs that keep customers signed up for more than a year have only 15 percent. Therefore, keeping connected connected to these additional incentives can be a boon for developers, even if they have to offer discounts in the short term.
