Discord
Discord Family Center
For the gaming chat app many teens live in, this is the tool that works without breaking trust. Your teen generates a QR code in Family Center, you scan it with the Discord mobile app, and the link only starts once your teen accepts it, so nothing is shared without their consent.
The dashboard and weekly email cover the past week: the servers they have joined or taken part in, the friends they have recently added and who they have messaged or called, never the conversations themselves. That is enough to notice a sudden flood of new contacts or an unfamiliar server and ask about it, which is the conversation that actually keeps teens safe.
