Facebook confirmed to Engadget that it's working on the feature. "We're always working on new ways to help make sure people's time on Facebook is time well spent," a spokesperson told TechCrunch. It's unclear when the tool will arrive on Android or any additional platforms.
This makes Facebook the latest tech company to start working on a tool to inform users of how much time they spend on the service. At its I/O conference in May, Google introduced several features in Android and YouTube to help folks track and manage their time spent in apps and services. A month later, Apple introduced similar features for iOS to assist users in controlling their and their children's screen time. (Whether those tools aren't effective enough or end up just nagging are other questions.)
It's one thing for device makers to see the change in public opinion (or from their investors) and help users wean themselves away from overdosing on their screens. It's another for a platform like Facebook, which needs people staying engaged and clicking on ads. Yet its Q4 2017 report released in January showed that users are spending less time on it than in previous years -- yet it's making more money than ever.
