In a continuation of it’s I/O conference, Google held a session on how to make money on the Andriod operating system. It shared some statistics on why its app store is worth investing in, and they were truly impressive: in-app purchase revenue growth jumped 700% in one year, which is reflected in the top apps as listed by highest grossing titles in the Play rankings. Subscriptions – introduced just a year ago – is showing revenue that’s doubling every quarter. Google, then, is suggesting in-app purchases are a great way for companies to make revenue while also advertising their product. As well, Google noted that there is a 1.7x higher purchase rate on tablets than on phones for apps, and updated apps that take advantage of new operating systems and capabilities perform at almost double the rate of monetization.
