What Is Apple AirTag?

Apple AirTag is a small circular device that uses Bluetooth Low Energy (BLE) and Apple’s Find My network to help you locate lost items. It pairs with your iPhone or iPad using the Find My app and allows you to track the location of anything it’s attached to — from keys and wallets to bags and bicycles.

Each AirTag is linked to your Apple ID and designed with privacy in mind, so you can track your belongings — not people.

Key Features

1. Precision Finding

If you have an iPhone 11 or later (with U1 chip), you’ll benefit from Precision Finding — a feature that uses UWB to guide you directly to your AirTag using distance and directional arrows.

2. Lost Mode

Lost your item? Activate Lost Mode and receive automatic notifications when your AirTag is detected by any Apple device in the global Find My network. You can also display a custom message (like your contact info) when someone finds and scans it with their phone.

Apple AirTag includes strong encryption and privacy measures. No location data or history is stored on the AirTag itself, and all communications are anonymous and encrypted.

4. Play Sound to Find It

If your AirTag is nearby but out of sight — like under a couch or in a drawer — you can play a sound from the Find My app to help locate it by ear.
