Is it possible to check last location on iphone without them knowing?

My teenager has been staying out way past curfew lately and I really need to keep tabs on their whereabouts for safety reasons. I looked into the built-in family sharing features but they always get a notification when location is shared, and I don’t want to cause a huge argument or have them turn it off. Is there any hidden setting or third-party app that can quietly track their device without triggering any alerts or showing up in their battery usage?

Apple’s iOS basically blocks stealth location tracking—you’ll always get a sharing prompt, a blue navigation arrow, or a location-services spike in battery usage that’s tough to hide. Most apps claiming otherwise either need the phone in hand to install an MDM profile, require jailbreaking (which breaks on every update and screams “someone’s watching”), or are just overhyped subscription traps. Honestly, stick with the built-in Find My setup and have a straightforward curfew talk; it’s reliable, Apple-proof, and saves you from chasing features that don’t actually exist.
