Apple AirTags: Everything You Need to Know

Apple AirTags are small, coin-sized Bluetooth trackers that help you find lost items like keys, bags, or luggage using the Find My network. You attach one to an item, pair it with your iPhone or iPad, and then locate it on a map, play a sound, or get directions when it’s nearby. This article covers how AirTags work, what you need to use them, common problems, and how they compare to other trackers.

Background and Purpose

Apple introduced AirTags in April 2021 as a direct answer to trackers like Tile. The core idea is simple: instead of relying on GPS (which drains batteries and needs cellular service), AirTags use Bluetooth to ping nearby Apple devices. Every iPhone, iPad, and Mac that passes within Bluetooth range anonymously reports the AirTag’s location to Apple’s Find My network. This crowd-sourced approach means the more Apple devices exist in the world, the more accurate and useful AirTags become.

AirTags are not GPS trackers. They don’t have a SIM card and can’t connect to the internet on their own. They only work when they’re within Bluetooth range of an Apple device (roughly 30-100 feet in open air) or when they’re in a lost mode and another Apple device detects them. For most personal items, this is more than enoughâ€”you’re rarely looking for something in a completely device-free area.

How AirTags Work

Each AirTag contains a Bluetooth chip, a U1 ultra-wideband chip (in the second generation), a speaker, and a replaceable CR2032 battery. The U1 chip enables Precision Finding on iPhone 11 and later models, which shows an arrow pointing to the AirTag and a distance readout in meters. This works only when the AirTag is within about 30 feet and in line-of-sight.

When you set up an AirTag, you place it near your iPhone and follow the on-screen prompts. The AirTag is then linked to your Apple ID. You can name it (e.g., “Keys” or “Backpack”) and assign an emoji. The Find My app shows the last known location and the time it was seen. If you lose an item, you can put it into Lost Mode, which notifies you when the AirTag is detected by the network and lets you leave a contact phone number that appears on someone’s iPhone if they tap the AirTag with their phone.

For nearby items, you can play a sound from the AirTag’s speaker. The speaker is intentionally quiet to prevent someone from finding a hidden AirTag easily, but it’s loud enough to hear under a couch cushion or in a backpack.

What You Need to Use AirTags

AirTags require an iPhone or iPad running iOS 14.5 or later. They do not work with Android phones (though Apple released an Android app for detecting unwanted AirTags, not for tracking your own). You also need to be signed into iCloud with two-factor authentication enabled. The Find My app must be turned on.

Here’s a quick checklist:

iPhone or iPad with iOS 14.5 or later
iCloud account with two-factor authentication
Find My app enabled
Bluetooth turned on

Precision Finding (the arrow and distance) requires an iPhone 11 or later with the U1 chip. Older iPhones can still use the sound and map features, but not the arrow.

How to Choose an AirTag Accessory

AirTags themselves are small and have no hole for a keyring. You need an accessory to attach them. Apple sells a leather key ring and a loop, but many third-party options exist. When choosing an accessory, consider:

Attachment method: Key rings, loops, adhesive mounts, or luggage tags.
Durability: For outdoor use, look for waterproof or dustproof cases.
Size: Some accessories add significant bulk; a flat adhesive mount is better for a TV remote or a bike.
Security: For luggage, a holder that hides the AirTag is better to prevent theft.

You can also buy a four-pack of AirTags at a slight discount per unit. The battery lasts about a year with normal use, and you can replace it yourself by twisting the back cover off and inserting a new CR2032 battery (positive side up). The AirTag plays a sound when the battery is low.

Common Problems and Misconceptions

One of the most discussed issues is the anti-stalking feature. AirTags are designed to alert people if an unknown AirTag is traveling with them. If an AirTag that isn’t paired with your Apple ID is near you for a while, your iPhone will show a notification and play a sound. On Android, Apple released a “Tracker Detect” app, but it requires manual scanning. This feature is good for safety, but it has made AirTags less useful for tracking stolen itemsâ€”a thief’s phone will alert them to the AirTag’s presence.

Another misconception is that AirTags work like GPS trackers for real-time location. They don’t. You see the last time the AirTag was seen, not a live position. If you’re tracking a moving car, you might see a location from 10 minutes ago, then nothing for an hour. For real-time tracking, you need a cellular GPS tracker with a subscription.

AirTags vs. Other Trackers

The main competitor is Tile (now owned by Life360). Tile trackers work with both iOS and Android, and they have a similar crowd-sourced network, but it’s much smaller than Apple’s. Tile doesn’t have Precision Finding with an arrow; it just shows a proximity bar. Samsung SmartTags work only with Samsung Galaxy phones and use a network of Samsung devices. Chipolo and other brands also exist, but they all rely on their own networks.

The biggest advantage of AirTags is the sheer size of the Find My network. With over a billion active Apple devices, the chance that a lost item is detected is very high, especially in urban areas. The biggest disadvantage is that they don’t work with Android, so if you have a mixed household, you might prefer a Tile or a Chipolo that works with both.

For pets, AirTags are not recommended. They’re not GPS trackers, and they’re too large for a cat collar. Dedicated pet trackers like the Whistle or Fi are subscription-based and use GPS/cellular. For a dog that might run off, a GPS tracker is more reliable.

Safety and Privacy

Apple has implemented several safety features to prevent AirTags from being used for stalking. If an unknown AirTag is detected moving with you, your iPhone will alert you. You can also scan for AirTags using the Find My app on iPhone or the Tracker Detect app on Android. If you find an unknown AirTag, you can disable it by removing the battery (twist the back cover counterclockwise).

Apple has also made the AirTag speaker sound louder in the second generation to make it easier to find hidden trackers. However, some privacy advocates have noted that the anti-stalking alerts are not always immediateâ€”it can take a few hours before you’re notified. If you’re concerned about being tracked, you can check your Find My app for unknown items.

Frequently Asked Questions

Do AirTags work with Android phones?

No, AirTags require an iPhone or iPad to set up and track. You can use Apple’s Tracker Detect app on Android to scan for unwanted AirTags near you, but you cannot use an AirTag to track your own items with an Android phone.

How long does the AirTag battery last?

About one year with normal use. The battery is a standard CR2032 coin cell, which you can buy at most stores. When the battery is low, the Find My app will show a low-battery warning, and the AirTag will play a sound when you remove the battery.

Can I use an AirTag to track my car?

Yes, but with limitations. AirTags are not GPS trackers, so you won’t get real-time location. You’ll see the last location where the AirTag was detected by an Apple device. If your car is in a parking garage with no Apple devices nearby, you won’t see it until you’re close. Also, if a thief has an iPhone, they’ll be alerted to the AirTag’s presence.

Are AirTags waterproof?

The AirTag itself has an IP67 rating, meaning it’s dust-tight and can survive submersion in up to 1 meter of water for 30 minutes. However, the battery compartment is not sealed, so after water exposure, you should dry it thoroughly before opening it. For heavy water use, consider a waterproof case.

Can I put an AirTag on my pet?

Technically yes, but it’s not recommended. AirTags are not GPS trackers, so you won’t know your pet’s location in real time. They’re also too large for small pets and could be a choking hazard. For pets, use a dedicated GPS tracker designed for animals.

Why does my AirTag beep randomly?

This is the anti-stalking feature. If an AirTag is separated from its paired iPhone for more than three days, it will play a sound to alert anyone nearby. If it’s your own AirTag and it’s beeping, it might be because it’s been away from your iPhone for a while. Move it near your phone to reset the timer.
