Apple AirTag

In an iPhone household, this is simply the default tracker for keys, a bag, or checked luggage. The second-gen AirTag taps the Find My network to locate what you've misplaced, and upgraded Ultra Wideband and Bluetooth chips push both ping range and Precision Finding farther — now with step-by-step directions on Apple Watch as well as iPhone. A 50% louder speaker makes the last few feet easier, and you can temporarily share an item's location with trusted contacts or over 50 airline partners. Battery lasts more than a year and swaps easily. The catch is obvious: it's built for Apple, so Android users should look elsewhere.
