Facebook is launching an app that will pay users to share information with the social media giant about which apps they're using. The company previously rolled out two similar apps. But both were shut down after drawing criticism for infringing on privacy, and one was cited for violating Apple's App Store terms of agreement.
Facebook said the new app, called Study, is different than the previous two and was built from scratch. And it is only available on the Google Play Store, though Facebook said it might work to expand it to iOS in the future.
