True to making things just a little simpler and easier for all, Google has officially enabled in-app subscriptions in its Play Store. While in-app billing brought developers “more ways to sell and engage users over the lifetime of their apps”, subscriptions will now give developers the ability to charge a monthly fee in order to have premium content in a product. The good thing is that in-app subscriptions aren’t just limited to games as you might imagine— Google has confirmed that there is the ability to subscribe to items such as a publications too.
Google also makes it simple to allow users to not only use, but extend their subscriptions to whatever service it is they are using. It has confirmed developers can offer users the ability to carry their subscriptions across multiple properties, services, or campaigns by introducing a useful API. This API can extend access from their Android apps to their web properties, based on subscriptions that are purchased on Google Play. Pretty cool indeed.
As of now, the addition is limited to Play Store version 3.5 users only. Also, there’s a small number of titles supporting this with Glu Mobile and its Frontline Commando property to start off with— but you can bet you’ll be seeing your favorite news publication or magazine or app take advantage of this service as well.
