Facebook is offering to pay people who download a new app that tracks what they do on their phones.
The company on Tuesday announced the new app, called Study, which will collect data about its users. Study will report back to Facebook about the apps that users have on their phones; how much time they spend on those apps; what they do on them, the country they live in, and the type of device they use.
Facebook said it will use the information it collects to help develop its own products.
