There are indications that Google may launch a new paid subscription service called Play Pass for Google Play which essentially bundles apps into a subscription. This may be because mobile app payment is not the most popular option for people, and bundling in a subscription could simplify things.
This year in June XDA Quinny899 discovered the above-mentioned development following an APK teardown in the Play Store. Code references of a Play Pass app subscription service have been discovered.
Also on October 25, the site found a survey about the Google Opinion Rewards program mentioning the service.
The survey asked a question about a service that "offers a subscription that offers paid apps and games in the hundreds of dollars for a monthly fee." He went on to ask how well "passport" describes the names of such a service.
The monthly rate is currently unknown. There is also no information about when the feature goes live. There is also no official communication from Google about the same.
That sounds like Apple's "App Bundles" that allow customers to buy up to 10 apps in a single purchase. It could be a great way to save money, especially for people who play a lot of games. Bundles contain several apps that can be purchased together at a reduced price. The feature was first introduced with iOS 8.
Recently, Apple first extended its App Bundles feature to Mac apps and free apps with a subscription.
Apple App Bundles have an app limit, we do not know if apps work in the Play Store.
