Google today announced that it will follow Apple’s lead in lowering the amount of money app developers must pay for mobile subscriptions processed through the Play Store. Back in June 2016, Apple introduced a new policy for its App Store to encourage developers to sell subscriptions as in-app purchases within iOS. That involved reducing the standard App Store transaction fee from 30 percent to 15 percent. It took effect in September of last year.

Now, Google is doing the same. Similar to Apple’s approach, an Android developer selling a subscription service will be eligible for the cut so long as the customer in question has been subscribed for more than a year. The company plans to put it into effect starting January 2018.
