I just checked the screen time report for my kids. My 16 year old averages 3 hours per day on her phone. My 12 year old
averages about 1.5 hours per day. The 16 year old uses apps for her theater group a lot but also spends some time on YouTube (we monitor that pretty closely). No social media.
The 12 year old’s top app was some horse game. Also no social media.
