We first heard in June that Facebook was working on a feature to help you track and manage the amount of time you spent in its mobile app. Following a delay after the company announced its rollout in August, it’s finally here.

Like the new ‘Your Activity’ feature that was introduced in Instagram last week, the ‘Your Time on Facebook’ dashboard displays a graph showing you how much time you’ve spent on the social network’s app over the past week.
