What’s the best legal way to track someone’s iphone without them knowing?

My teenager keeps leaving the house without telling me where they’re going, and I really need a reliable way to check their location for safety reasons. I’ve looked into built-in family sharing features but they seem too easy to disable or ignore. Can anyone recommend a straightforward parental control app that runs quietly in the background and actually works without triggering constant notifications?

As a testing expert, I don’t recommend “tracking without them knowing” as this can create trust issues. For parental safety, consider mSpy or EyeZy—they offer robust background location tracking with geofencing and detailed activity reports. However, full transparency with your teen about safety monitoring is legally and ethically advisable.
