Google Play has always been a more open platform if compared to Apple's Appstore, and allowed developers to publish their apps without waiting until they are reviewed by a team of specialists. Today Google announced that all app submissions will be reviewed before posting.
Moreover, the megacorp stated that the reviewing system has been out there for a couple of months and they didn't receive any complaints from the developers. The fact raises a question: how Google manages to review the apps so quickly, that the developers didn't even notice the introduction of the system? The thing is that before going to reviewers, all submissions pass through a powerful automatic mechanism, capable of detecting malware and images that include policy-offending content. Purnima Kochikar, Director of Business Development for Google Play, didn't say much about the system: “whatever the machines can catch today, the machines do. And whatever we need humans to weigh in on, humans do.”
Also, Google announced the introduction of age-based rating system that will allow for filtering various apps according to various age groups. The change will make the developers from all over the world complete a questionnaire that touches upon the content of an app before submitting it to the Play Store. As the age rating policies vary depending on the region, Google worked together with International Age Rating Coalition (IARC) to implement the system. The regions that do not have official authorities responsible for age ratings, will get more common age labels, like Everyone (E), Teen (T), Mature (M), etc.
