AirTag

AirTag is a tracking device developed by Apple. AirTag is designed to act as a key finder, which helps people find personal objects such as keys, bags, apparel, small electronic devices and vehicles. To locate lost or stolen items, AirTags use Apple's crowdsourced Find My network, estimated in early 2021 to consist of approximately one billion devices worldwide that detect and anonymously report emitted Bluetooth signals.

AirTags are compatible with any iPhone, iPad, or iPod Touch device capable of running iOS/iPadOS 14.5 or later, including iPhone 6S or later (including iPhone SE 1, 2 and 3). Using the built-in U1 chip on iPhone 11 or later (except iPhone SE and iPhone 16e models), users can more precisely locate items using ultra-wideband (UWB) technology. AirTag has been available since 2021.

An updated model with the U2 chip, upgraded Bluetooth, and a louder speaker was released in January 2026. It has enhanced range for precision detection with iPhones equipped with a U2 chip such as the iPhone 15/Pro or later (excluding iPhone 16e), and also allows an Apple Watch with a U2 chip such as the Apple Watch Series 9 or later, or Apple Watch Ultra 2 or later (excluding Apple Watch SE), to precisely locate items. The second generation AirTag is compatible with devices running iOS/iPadOS/watchOS 26.2.1 or later.
