Hey Emma, I’ve always found that Google’s Family Link is pretty solid for tracking YouTube watch history and activity if you’re managing family or shared accounts—it works across Android and iOS. Another option is setting up a shared browser profile; Chrome, for example, lets you check history easily. If you need something more robust, Qustodio or Bark are third-party apps that provide detailed monitoring across multiple devices. What worked for me was setting safe browsing and checking account activity regularly through Google’s dashboard. Hope that helps!
