Apple AirTag 4 Pack Review: Four Trackers That Only Make Sense Inside An iPhone Household

Three ways to find a tag, and the network that costs nothing

An AirTag has three finding modes and they cover different distances. Up close, the Items tab in Find My plays a sound through the built-in speaker, which Apple rates as 50% louder on the second generation so it can be heard from up to twice as far.

In the same room or the same car, Precision Finding uses the Ultra Wideband chip to show distance and an arrow. The longer range, up to 1.5 times the original tag's, needs an iPhone Air or an iPhone 15 or later, and Apple excludes the iPhone 16e and 17e. Precision Finding also works on the wrist with an Apple Watch Series 9 or Ultra 2 or newer running watchOS 26.2.1.

Everywhere else, the Find My network takes over. The tag broadcasts a rotating Bluetooth identifier, any of what Apple describes as more than a billion iPhones, iPads and Macs that pass by relays its position to iCloud, and the owner sees a map pin. Apple stores no history on the tag, encrypts the relay so it cannot see the location itself, and charges no fee for any of this. Lost Mode adds a notification when the tag is next seen and lets a finder tap it with an NFC phone to get your contact details, and a lost item's location can be shared with more than 50 airlines for up to seven days.

Setup needs an iPhone or iPad, and Android gets alerts only

Apple's setup is a one-tap pairing sheet that appears when a new tag is held near an iPhone; you name it, attach it and you are done. The requirements behind that sentence are strict: an iPhone on iOS 26.0 or later, or an iPad on iPadOS 26.0 or later, signed into an Apple Account with iCloud. There is no Mac, no web page and no Android app that can pair an AirTag, so a household where the phone that will do the searching is not an iPhone has no way to use this pack at all.

Android phones are in the picture only on the safety side. If someone else's AirTag travels with an Android user, that phone can raise an unwanted-tracking alert, and after a while the tag itself starts chirping. Apple's instruction page puts the limit plainly: a Find My network accessory "should not be used to track people, and should not be used to track property that does not belong to you". Within an iPhone household the reach is wider: a tag can be shared with up to five people, so the family car keys or the shared umbrella show up in everyone's Items tab and anyone can ping them.

A CR2032 you swap yourself, in an IP67 disc with no loop

The battery is the ordinary CR2032 3 V lithium coin cell, installed in the box and rated by Apple for more than a year of typical use, defined as daily sound playing and Precision Finding. When it runs low, Find My puts a Low Battery line under the tag's name. Replacement is a press down and a counterclockwise turn of the polished steel cover until it stops, a fresh cell dropped in positive side up, and the cover turned back until its three tabs line up with three slots. Apple adds one caution: some bitterant-coated cells, sold to deter children from swallowing them, might not work with AirTag, so look for packaging marked compatible with it.

The disc measures 1.26 inches across, 0.31 inch thick, and weighs 0.42 ounce, with an IP67 rating for one meter of water for 30 minutes, tested in a lab and not guaranteed for the life of the tag. Apple's own spec notes that resistance can drop with wear. There is no keyring hole, which is the design's one recurring annoyance: every tag needs a loop, a sleeve or a pocket, and Apple's FineWoven Key Ring adds $35 per tag. The second generation keeps the original footprint, so third-party holders made since 2021 still fit, and the enclosure is 85% recycled plastic.

$17 saved over singles, one year of coverage, 14 days to change your mind

Apple lists $29 for one AirTag and $99 for four, the same prices as the 2021 model, so the four-pack saves $17 against buying singly. The shop page carries both figures next to the free engraving of initials or an emoji, which exists only on apple.com and in the Apple Store app; a box picked up elsewhere arrives plain.

AirTag falls under Apple's one-year accessory warranty, which runs from the original retail purchase and lets Apple choose between repair, exchange for the same model or a refund; normal battery depletion is excluded, which for a device with a user-replaceable cell is unlikely to matter. Apple's US retail policy allows a return or exchange with a receipt within 14 days of delivery, in original condition with all parts and packaging, and refunds the difference if Apple lowers the price within 14 days.

Skip it if the finding phone runs Android

The hard stop is the platform. If the phone that will hunt for the keys is an Android device, the four-pack is $99 of discs that cannot be paired, and the only thing they will ever do on that phone is warn its owner that someone else's tag is nearby. An iPad on iPadOS 26 can set them up, but nobody wants to carry a tablet through a parking garage, so treat this as an iPhone accessory and choose a tracker built for Android's network otherwise.

Pass on the pack, too, if the job is tracking a person or an animal; Apple designed the anti-stalking alerts to defeat exactly that, and a tag on a dog will start beeping when the dog wanders off with a stranger. And if you lose one thing and one thing only, a $29 single is the honest buy. The pack only earns its price when at least four objects deserve a tag and a holder each, which for most people means the luggage, the keys and whatever they leave in cafes.
