Even before the announcement, Apple's AirTags have gained a new feature: If someone tries to stalk you by hiding an AirTag in your clothes, car or bag, your iPhone will detect it and send you an alert.

AirTags are Apple’s long-awaited tracker tiles, tiny tags that appear in your phone’s Find My app, helping you locate lost keys or keep your checked bags secure. But are AirTags private? Could they leak private information and let other people find you? Probably not.

“I’ll use them if they’re not too expensive,” iOS app developer Graham Bower told Lifewire via direct message. “It can’t be worse than an Apple Watch.”

Apple’s Find My feature, built into all recent Mac and iOS portables, is a masterclass in clever design. Finding a lost phone is, in principle, easy. Thanks to GPS, the iPhone always knows where it is. And if it’s connected to the internet, it can tell you.
