Instagram is getting a new “Usage Insights” tool that helps users see how much time they’ve spent in the social media app, according to a discovery from app researcher Jane Manchun Wong who found the feature hidden in the code of Instagram’s Android app (via TechCrunch).

Instagram CEO Kevin Systrom later confirmed the original report in a series of tweets, commenting that the company is “building tools that will help the IG community know more about the time they spend on Instagram — any time should be positive and intentional.”
