Apple’s new device, the AirTag, can help you keep track of items like your backpack or keys. After attaching the device to an item, you can use Apple’s Find My network to track it via your iPhone, iPad or Mac. The AirTag is built with the same U1 chip that the iPhone 11 and iPhone 12 are equipped with — together, the chips give you a more precise estimate of where your item is located. iPhone 11 and 12 owners also have access to the AirTag’s Precision Finding tool, which gives you AR overlays to direct you towards the item you’re tracking. Those who own a different iPhone model can connect to the AirTag via Bluetooth LE, and all users can track their AirTags in Apple’s Find My app. If you need to locate an AirTag, you can also prompt it to make a sound. The Airtag is sold individually or in a pack of four, and they’re built with a user-replaceable battery (Apple says it should last about a year). The AirTag is currently shipping.
