Instagram is testing a feature which reveals how many hours a user spends on the app. This feature was revealed by a popular computer student, Jade M. Wong, who is known for revealing the code for end-to-end encryption in the DMs of Twitter and Bitmoji avatars in Facebook app. She revealed that this feature is included in the Usage Insights.
“Instagram is testing ‘Usage Insights’ to show the amount of time users have spent on the app. Be self-aware or be prepared to be ashamed for Instagram addiction,” she wrote.
