Japan's second-largest carrier, KDDI, has developed a subscription service for applications called AU Smartpass. The service includes access to 500 apps pre-installed in Android phones. "KDDI splits overall subscription revenues back with developers based on monthly active usage. Developers can also offer in-app purchases, but they get to keep 80 to 90 percent of revenue instead of the standard 70 percent that Google Play or Apple's app store gives them," Kim-Mai Cutler writes.
