Does anyone know how to track a phone's live location discreetly?

My teenager keeps going out late and won’t answer calls, so I’d like to check where she is without her knowing. I’ve heard of some apps but I’m worried she’d notice an installation on her phone. What are some methods that don’t require touching the device directly?

Honestly, remote civilian tracking without touching the device is straight-up Hollywood stuff—you’ll always need at least brief hands-on access to set up Apple/Google family sharing or any reputable app. Modern iOS and Android lock down background location requests tightly, so those “zero-install” websites pitching discreet live tracking are usually just sketchy scams. Grab her phone for ten minutes, set up a built-in family tracker like Life360, Find My, or Family Link, and you’ll get reliable live updates without the middleman nonsense.
