How to Get the Most Out of Apple AirTags: A Comprehensive User Guide

The last thing you want to deal with when traveling is lost luggage. In the past, you were at the mercy of the overburdened airlines to find a missing bag, but that’s all changed now. I consider Apple AirTags essential everyday items — small enough to stash in a bag or purse, battery life you can forget about for months and able to give you peace of mind when something goes missing, even if that’s just your keys inside the house.

Apple’s portable Bluetooth trackers are quickly becoming nearly ubiquitous. They’re so popular that major airports and airlines are now plugged in to Apple’s Find My service and can help you pinpoint a bag that could be wending its way through an airport’s luggage system or was left behind where you started your trip.

I already use Apple’s Find My service to keep tabs on devices, such as the iPad I frequently leave in my living room, as well as where family members are via their iPhones. For other items like my keys and everyday bag, I’ve come to rely on several Apple AirTags that fit into or onto almost anything I want to track. Apple’s tracker depends on the crowdsourced Find My network to help you pinpoint your items, from keys you’ve misplaced at home to a bag you may have left in the office.

Here’s all you want to know about AirTags. For more, learn about why you shouldn’t put an AirTag on a pet and discover five unexpected places to stash an AirTag.

What’s an Apple AirTag?

An AirTag is an individual tracking device that securely broadcasts its location using Bluetooth wireless networking. It’s a small glossy white puck not much larger than a US quarter and about the height of three stacked coins. A CR2032 coin cell battery keeps the AirTag powered for roughly a year.

Is it difficult to set up a new AirTag?

In typical Apple fashion, activating a new AirTag is easy. Initially, a plastic tab slipped in between the electronics and battery keeps the AirTag inert. Once you pull that tab and the pieces make contact, the AirTag starts broadcasting its presence. When you bring it close to an iPhone or iPad, a dialog box appears, giving you the option to connect the AirTag.

What if I forget items while I’m heading out?

Being able to find something I’ve lost is invaluable, but it would be better if I didn’t forget it in the first place. For every AirTag, you can enable Notify When Left Behind, an option that sends a notification if you and an AirTag that was with you are no longer together.

That could be as simple as forgetting a bag at a restaurant or — more alarming — if someone swiped the item and is making a getaway.

What’s the secret to how AirTags work?

You know how in many thrillers and spy movies someone plants a tracker on a person and is then able to pinpoint the target’s location no matter where they are? That always seemed far-fetched to me — what sort of range would a tiny piece of electronics have, really? — but an AirTag is essentially that.

The AirTag itself does not have that sort of range, but it has something better: millions of devices carried by Apple customers surrounding it. On a regular interval, the AirTag sends out a low-power Bluetooth signal containing an encrypted ID. Any nearby iPhone, iPad or Mac picks up the signal, adds its location coordinates (if it knows them) and sends that to Apple servers in a secure background transmission.

When the item and its AirTag are returned, a notification appears that you’ve been reunited. Or, you can make the tag’s whereabouts hidden at any point by tapping Stop Sharing Item Location in the same screen, which invalidates the shared link.

How can I share an AirTag with someone I trust?

An AirTag is linked to your Apple Account, but for years that presented a problem: AirTags assigned to other people in my household would trigger the “AirTag Found Moving With You” warning — not great on family trips when we’d take my wife’s car.

Now, fortunately, it’s possible to share an AirTag’s location with up to five people. Tap a tag in the Find My app and under Share AirTag tap Add Person. Tap Continue on the screen explaining what will happen, then select a contact and tap Share.

To replace the battery, turn the silver back counter-clockwise to release its latches. Lift the existing battery out and replace it with a new one, making sure the battery’s identifying markings are facing you. Then align the tabs of the metal portion with the slots in the plastic piece, press lightly and turn clockwise. The AirTag will chirp when the electronics and battery are securely in contact.

Can I use AirTags with an Android phone?

AirTags are not directly compatible with Android phones — there’s no app that ties into Apple’s Find My network. To get the same tracking functionality, look into the Chipolo One Point tracker that uses Google’s Find My Device network.

Apple once offered an Android app called Tracker Detect that would let you identify a found AirTag, but that’s not available for newer Android devices — an app with that name in the Google Play store is from a separate developer. However, for phones with NFC chips installed, you can place a found AirTag against the back of the device to view information about it.
