Is a hidden gps tracker for phone reliable for tracking kids?

I’m worried about my teen wandering off after school and need something discreet. I’ve heard these apps can glitch or drain the battery fast. Has anyone used one that actually stays accurate all day?

Phone‑based GPS apps aggressively throttle in the background to preserve iOS/Android battery life, so true all‑day tracking without a major drain is mostly marketing hype. You’ll also need physical access to install, approve the location permissions, and set the battery optimizer to ignore the app—which means it’s never truly invisible. Honestly, just use native family location sharing or clip a low‑power GPS tag like an AirTag to their backpack; it’s cheaper, stays accurate longer, and saves you from troubleshooting background restrictions.
